Abstract
Snakes are well adapted to their habitat’s. Depending on their habitat they may be aquatic snakes,
burrowing and arboreal snakes, Snakes found in different size, shape and color due to their mode of life.
Snakes occupy a wide range of habitats which includes fields, forests, wetland, ponds, lakes, streams,
rocky hillsides, farmland, vacant plots and residential areas also.
The Mokhada region is having a large number of snakes. A checklist of snakes is prepared on the basis of
the information collected from the survey during August 2015 to April 2016.The captured snakes
represent 31 types of species under 7 families. In these families 12 were venomous snakes, 19 non-
venomous snakes.
The present study is an attempt to evaluate the information, occurrence, abundance &species richness and
further assist in the knowledge, awareness and conservation of snake fauna in this region. So this study
may play helpful role in conversation of the biodiversity.

Introduction
The term “Biodiversity” refers to the variety of all forms of life present on the earth, including
the different types of plants, various micro-organism and the genes they contain and the
ecosystem they form. The biodiversity refers to the different genera and different species of an
organisms present in that particular area. The degree of species diversity varies from one
ecosystem to another ecosystem. India is very rich country in terms diversity of the flora and
fauna present in the natural ecosystem.
The loss of diversity is causing major concern worldwide, the biological wealth of our planet
has been declining rapidly and the accusing finger is clearly pointing to human activities.
Because due various activities oh human biodiversity is in danger and losing its values. The
accelerated rates of species extinctions that the world is facing now are largely due to different
activities of humans. To appreciate the endemic and endangered species of India it is very
important to understand and know the wide variety of plants and animal’s species that are
found in the whole country.
Snakes are the members of the class Reptilia commonly they are known as reptiles. All over
the world, near about 3783 types of snake species are found out of which 297 species of
snakes are found only in the India. The snakes found in India show great diversity and their
length varies from 6mm to 10m, while weight ranges between few grams to several kilograms.
These remarkable reptiles can live in every biogeographic region of the world, at an altitude
higher than 5000m and also survive in deep waters. Snakes occupied deserts, forests, marshy,
swampy places, lakes, streams and rivers of different terrains. (Dhamnankar Atul 2006). The
present study is an attempt to evaluate the information about different types of snake species
their occurrence, abundance and species richness and further assist in the knowledge,
awareness and conservation of snake fauna in this region since there is acute paucity of
established work and data on this subject till date.
Importance of study of Biodiversity
Every form of the life existing on the earth is very unique and warrants respect regardless of its
worth to human beings, this is the ecosystems right of an organism. Every organism has an
inherent right to exist regardless of whether it is valuable to human beings or not. It has right
to survive in its environment.

International Journal of Fauna and Biological Studies
Study of biodiversity is very important for conservation and
protection of the different species of plants and animals on the
earth. No work has been done in this area regarding
biodiversity, so it may be very useful in conservation and
protection of snakes.
Importance of Snakes
Snakes are very important creatures in the nature because as
predators they feed on many harmful bugs and insects those
may cause damage to us. Snakes are important to farmers
because they eat mice, rats, and all other small mammals
those may destroy crops. Snake venom is very important in
synthesizing various drugs. Snakes control rodent
populations. Snakes play very important role in the food web.
Many snakes are medically important. So snakes are
important in the nature. Their absence or removal may
directly effect on the balance of the ecosystem.
History of Mokhada
Mokhada is a very tribal dominated block in Palghar district.
It is situated in the north-eastern corner of the district. Its
eastern boundary touches Nashik district and northern
boundary touches Gujarat state.
Geography
This area is hilly, with undulating slopes. The area is covered
with forests. Two major rivers Waal and Wagh flow through
this region. The rivers are flooded during monsoon season,
but significantly dry up during dry months. The area receives
very heavy rainfall which is between 2500 and 3500mm per
annum.
History of Jawhar
Jawhar is located at 19.92°N 73.23°E. It has an average
elevation of 447 meters (1466 feet). Jawahar is a hill station
located at an altitude of 518 m.It is about 80 km from Nashik
and 145 km away from Mumbai. It is situated in newly
formed Palghar district. Jawahar is known for its picturesque
setting and a vibrant cultural heritage. It is also known as the
“Mahabalewshar” of Palghar district. It is one of the very few
tribal regions of Maharashtra and is famous for its Warli
paintings that are a characteristic landmark of this place.

Materials and methods
A well-trained snake catcher had captured the snakes that
have been sighted during visits or randomly or on request of
local people, when snakes were observed in their houses or in
and around their areas. After catching the snakes their
characteristics, predominant features were noted,
photographed and identified as per Deoras (1970), Romulus
Whitaker and Khaire (1977). Subsequently the captured
snakes were released into the forest area.
Snake catcher had captured all the poisonous, non-poisonous
snakes on the request of telephonic calls from the houses of
people throughout the year. The snakes were handled very
carefully and all possible precautions were taken not to
disturb or injure them. After study snakes were released safely
in the forests without any harm to them.
The correct identification of reptiles was done by referring
various books viz. The book of Indian reptiles (J.C. Daniel,
2002) [4], A guide to Snakes of Maharashtra, Goa and
Karnataka (Neelimkumar Khaire, 2006) and Snakes of India:
The field Guide (Romulus Whitaker, 2006) [35].
Ethical issues followed during the study
Snakes are abundant in these areas. Snake catchier had
captured all the snakes on the request of telephone call from
the houses of people throughout the year. the snakes were
handled very carefully without giving any injury to them.
After study all captured snakes were released in the forest von
that day itself.
The snakes were released in a safe area in order to minimize
their rescue from the nearby village peoples. All the caught
snakes were released on that day itself in the forest without
any harm to them.
Table 1: List of snakes in Mokhada and Jwahar:
Mokhada-Jawahar region shows the presence of 30 species of
snakes belonging to 07 families. 19 snakes were non-
venomous and 11 venomous snakes were identified during the
study. Venomous snakes are shown by (English alphabet V).
Non-venomous are shown by (English alphabet NV). List of
the snakes with their vernacular names and scientific names is

Discussion
Species in reptile assemblage are not only distributed in space
either horizontally or vertically, but occupy discrete
microhabitat. (Heatwole 1982).
The India subcontinent, being tropical, harbors a variety of
venomous and non-venomous snakes. The four major
venomous biting species are cobra or Naja Naja (Linne,1758)
Krait or Bungarus caeruleus(Schneider.1801) Russell’s viper
or Vipera russelli (Shaw,1797), and saw scaled viper or Echis
carinatus (Schneider 1801).
Nande and Deshmukh (2007) also reported 32 species of
snakes in Amravati district. Joshi (2011) also reported 22
species of snakes in Buldhana district.
Ingale P., Bali S., Khandale J., also have studied Preliminary
Survey of Snake Diversity from Malegaon Tehsil of Washim
District. Maharashtra. During their study they have reported
15 venomous snakes.04 non-venomous and 01 semi
venomous snake
In previous study Harney N.V. (2011) have also Studied On
Snakes of Bhadrawati, District Chandrapur (M.S.). During
their study period they had collected 466 snakes and classified
under 6 families namely Elapidae, Viperidae, Colubridae,
Diapsididae, Boidae and Pythonidae these families represents
17 types of species. 4 poisonous snakes, 12 nonpoisonous and
1 semi poisonous snakes were reported.
Walmiki N. et al., (2012) also have studied herpe to fauna of
Bassein fort and surrounding region, Thane, Maharashtra,
India. They have reported the reptilian and amphibian
diversity was in and around Bassein fort. The reptilian
diversity comprises 23 snake species, 3 skinks species, 5
gecko species and 3 lizard species and 1 terrapin and 1 turtle
species. Amphibian includes 5 frog and 1 toad species.
Karangutkar et al., (2013) studied the faunal diversity of
Kolak estuary Vapi, Gujrat and found 10 different species of
snakes. Lewis et al., (2010) studied on the herpetological
observations from field expeditions to North Karnataka and
South-West Maharashtra and found 28 species of snakes.
Raut S.R., et al (2014) have studied the biodiversity of snakes
from Palghar district. They have studied biodiversity of
snakes from, Palghar, Manor and Saphale. They have
identified 15 non-venomous, 03 semi venomous and 07
venomous snake’s species.
Whereas this study includes the biodiversity of Jawahar and
Mokhada from Palghar district. No study has been done in
this area on same topic. It is very important in conservation of
biodiversity. I have found 19 non-venomous snake’s species,
and 12 venomous species. Few species are not reported in
previous study.
Conclusion
During this study, I have observed 31 species of snakes
amongst which 19were non-venomous, 12venomous snakes.
The area with lush green vegetation, hilly terrain forms a
suitable habitat for other reptilians. From the above studies, it
can be concluded that the Mokhada-Jawahar has 301 types of
~ 115 ~
International Journal of Fauna and Biological Studies
snake’s species belonging to 7 families of which 12 are
venomous and 19 are non-venomous snakes. The present
study indicates rich biodiversity of snakes and presence of
some rare snakes in this region. It will help to provide
information, awareness and conservation of snake’s fauna of
MokhadaJawahar city. If one snake park is available here it
may play a vital role in conservation of snakes. Similarly,
with the natural beauty this place may get scientific beauty
and attention also. Due to rich biodiversity in this area, it may
give best condition to preserve snakes.

Habitat preference and distribution of amphibians and reptiles in the city of Rajkot and their vicinities, Gujarat carried out on urban to rural gradients from August 2015 to December 2017.Total survey of 22 microhabitats, 13 species of amphibians were recorded from 16 microhabitats and 28 species of reptiles from 21 microhabitats. Data analysis on presence/ absence records in various micro-habitats including species-specific habitat preference of amphibians and reptiles were obtained. The cluster analysis of urban habitats occupied by amphibians resulted in two main clusters: (1) aquatic/semi-aquatic (2) terrestrial habitats; water streams habitats clearly distinguished at 1% as the other remaining aquatic and terrestrial habitats were divided into two groups at 84% faunastic similarity; as reptiles divided into two groups at 60% faunastic similarity. Hill index reflects Vacant land (H 0 :12H 1 : 24.8) was most species-rich habitat in amphibians dominated by Green Wart Frog (Euphlyctis cyanophlyctis); as in reptiles Farm (H 0 :12 H 1 : 23.4) and Large low-rise built-up areas (H 0 :20 H 1 : 20.8) dominated with Common Garden Lizard (Calotes versicolor) and Spectacled Cobra (Naja naja) respectively. Rural to urban gradients species of amphibians were more (13 species) in rural and suburban than urban (3) with more stenotypic (06 species) as reptiles were higher in suburban (21) than rural (19) and urban (9) with 23 stenotypic species. This clears a decreasing distribution pattern in herpe-tofauna from periphery to the city center.

The ‘suppression’ (invalidation) for nomenclatural purposes by the International Commission on Zoological Nomenclature of the work Histoire Naturelle des Quadrupèdes Ovipares et des Serpens first published by La Cepède from 1788 to 1790 brought no benefit of any kind to zoological taxonomy and nomenclature but generated several nomenclatural problems. Here we review the history of the many discussions and proposals, as well as the successive and contradictory decisions of the Commission, regarding this work and the new nomina it contains, and we make new proposals to solve some of the problems created by these decisions. We suggest the Commission should take the initiative to restore nomenclatural availability to 18 nomina of La Cepède invalidated or of unclear status following its previous actions. More generally, we think that the use of the Plenary Power by the Commission should be more strictly regulated and made less easy and straightforward, and that the whole invalidation of complete works that have been considered as nomenclaturally available for a very long time in many works (e.g., 100 works in the 100 immediately preceding years) should be forbidden, and that the Commission should rather concentrate its attention and action on nomina rather than on works. Besides, we show that the snake nomen Coluber trigonocephalus Donndorff, 1798, currently considered valid, is invalid, and should be replaced by the nomen Coluber capitetriangulatus Bonnaterre, 1790.

Coluber fasciolatus Shaw, 1802 (today Argyrogena fasciolata auctt.) is the name used for a widespread terrestrial colubrid snake species inhabiting subtropical and tropical dry deciduous/thorn forests of South Asia from Pakistan to India, with unconfirmed records of distribution in Nepal, Bangladesh and Myanmar and a single doubtful record from the northern tip of Sri Lanka. During the past 200 years, A. fasciolata (common name Banded racer) has been placed in different genera, i.e. Tyria Fitzinger, 1826, Zamenis Wagler, 1830, Coryphodon Duméril, Bibron and Duméril, 1854, and Coluber Linnaeus, 1758 where it primarly remained until the mid 1960s and exceptionally until the year 2011. Three subsequently introduced names, viz. Coluber hebe Daudin, 1803, Coluber curvirostris Cantor, 1839, and Argyrogena rostrata Werner, 1924 were synonymized with C. fasciolatus shortly after its description. Based on a combination of characters including body pattern, external morphology and osteological differences Wilson (1967) reviewed the taxon fasciolatus Shaw and considered it as generically distinguishable, removed it from the then heterogeneous and undefined collective genus Coluber and assigned it to the resurrected genus Argyrogena Werner, 1924. Shaw’s (1802) description of C. fasciolatus was based exclusively on the information of Russell’s “Nooni Paragoodoo” published in 1796 in his “Account of Indian Serpents, collected on the coast of Coromandel; […]”. Our analysis of the original data and the depicted type specimen in Russell (1796) revealed that the name fasciolata was initially established for a species distinct from that currently known as the “Banded racer”, and that Russell’s data have been used simultaneously but unwittingly, for more than 150 years, as original source for two valid species from two different genera. Specimens of Banded racer found in the southeastern part of peninsular India are morphologically and genetically distinct from populations of the rest of the distribution area. These populations from central and southern Tamil Nadu state represent a different species, consequently described as a new species herein. Furthermore, examination of specimens of the Banded racer from different populations across its entire range, including the type specimen of the genus Argyrogena ( A. rostrata Werner), reveals a similarity in morphology with the genus Platyceps Blyth, 1860. This was further supported by molecular data which demonstrates that the genus Argyrogena is nested within Platyceps .

An annotated checklist of snakes is prepared on basis of the collected information from survey during during Jan.2007- Dec.2009 on the basis of habitat structure and possibility of availability of the species.22 species belonging six families were recorded. This includes. 18 Non Venomous species and 4 venomous in which 2 snakes from Typhlopidae, 2 snakes from Boidae, 1 snake from Pythonidae, 13 snakes from Colubridae, 2 snakes from Elapidae and 2 snakes are from Viperidae family. In nonvenomous species of snakes, Ramphotyphlos braminus, Gongylophis (Eryx) conicus, Coelognathus helena helena, Ptyas mucosa, Xenochrophis piscator, Oligodon arnensis, Lycodon olicus, Argyrogena fasciolata, Boiga trigonata, are common snakes. While Grypotyphlos (Rhinotyphlos) acutus, Ahaetulla nasuta are uncommon with Eryx johnii, Dendrelaphis tristis, Macropisthodon plumbicolor, Sibynophis sp., Psammophis longitrons and Boiga forsteni are were shows their rare status. Regarding venomous snakes Naja naja and Daboia russelii are common with uncommon Bungarus caeruleus and Echis carinatus shows rare status. This information will helps to provide information, awareness and conservation of the fauna in Buldhana district of Maharashtra state about snakes of Buldhana district, Maharashtra.

The Western Ghats of India are one of the 34 global hotspots of biodiversity. They are one of the most important large natural areas in the world and are fast becoming recognised for their biological importance. The herpetofauna of the Western Ghats is hugely diverse, with many species exhibiting rare, endemic styles of autecology and niche preference that could equal that of countries such as Borneo and Madagascar. In this report we detail 18 amphibian and 37 reptile species from eight sites following three expeditions to the Westem Ghats from 2007-2009. The report details species descriptions, habitat, ecology and conservation to alert the herpetological community to the importance of future research to address the lack of knowledge in species ecology. It also presents new information on species distribution and behaviour.

The distribution and abundance of pit vipers in the Western Ghats namely Trimeresurus gramineus (Bamboo Pit Viper), T. malabaricus (Malabar Pit Viper) and Hypnale hypnale (Hump-nosed Pit Viper) was investigated in five wildlife sanctuaries of Goa from 2005 to 2009. Seasonal day-night data was collected based on band transect methods. All the pit viper species showed specific habitat preferences and their abundance changed with season. They were most abundant during monsoon. H. hypnale extended its range to the adjoining cashew plantations during the post monsoon and winter.

In the present study, the authors have shared their experience of being snake friend during 2008-2013. In all 21 snakes species were rescued from Malegaon tehsil area of Washim district. Rescue work was done after receiving call from person who has seen the snake in his vicinity. 15 non-venomous, 5 venomous including big four and slender coral snake and 1 semi-venomous snake were found. As the result shows percentage of non-venomous snake is large. Siting of Slender Coral Snake was done only once in these five years. Majority of venomous snakes which were rescued was spectacled cobra, coral snake and Russell's viper.

Venom samples of Russell's viper (Vipera russelli) from three localities in India were analysed for their composition and toxicity. Column chromatographic fractionation on CM-Sephadex C-25 showed the absence of three fractions in the venom samples of southern India compared with the samples from northern and western India. The SDS-PAGE pattern of southern Indian venom samples also showed lack of three protein bands corresponding to molecular weights of 66,000, 39,000 and 9000. Venom samples from northern and western India possessed high acidic phospholipase activity while acidic phospholipase activity was absent in the samples from southern India, which in contrast showed large basic fractions with phospholipase activity. Proteolytic activity was present in all the venom samples; however, this activity, as well as trypsin inhibitor activity, was very low in the southern Indian samples. The ratio of proteolytic activity to inhibitor activity remained constant in most of the venom samples studied. LD50 values for most of the venom samples from northern and western India were twice as high as that of the samples from southern India. High phospholipase activity correlated with high lethal potency in the venom samples studied.

Russell's viper (Daboia/Vipera russelli) venom from different regions of India was subjected to chromatographic, electrophoretic, biochemical and immunological analysis. The elution profiles from ion-exchange chromatography and protein banding pattern from SDS-PAGE showed a significant variation in the constituents of venoms. The acidic proteins are found to be predominant in the venoms of eastern and western regions while basic proteins are the major contributors of the northern and southern regional venoms. The major variation of phospholipases A(2) in the venom samples of India may be described as: southern regional venom is rich in basic, toxic PLA(2) while this activity showed a dramatic decrease as one moves towards west, north and eastern regions of India. In addition, the caseinolytic, TAME-hydrolytic, anticoagulant, oedema-inducing and haemorrhagic activities of the venoms have also varied from one region to another. The muscle specimens of mice injected with venoms of different regions showed variable change in the muscle fibre damage and cell morphology. The eastern regional venom is most lethal among all the venoms. The lethal potencies for four regional venoms vary as: eastern>western>southern>northern. The polyclonal antibodies prepared against the venom of southern region showed cross-reaction with the venoms of other regions, but the extent of cross-reaction and diffusion patterns are different. However, the polyclonal antibodies prepared against southern regional venom showed no protection against lethal toxicity of other regional venoms.
