Abstract: In this study, a revised checklist of macroalgae
of Iran with an updated nomenclature and taxonomy has
been compiled based on published records. Using cur-
rently accepted names, 309 species and infraspecific taxa
of macroalgae have been identified to date, including 78
Chlorophyta (within 15 families), 70 Ochrophyta (Phaeo-
phyceae; within 7 families) and 161 Rhodophyta (within
30 families). The brown alga Sargassum with 25 taxa was
the most diverse genus, and the Rhodomelaceae (Rhodo-
phyta) with 36 taxa was the most species-rich family. The
Cheney ratio of 3.4 and the species composition of brown
seaweeds suggest that the Iranian marine algal flora is
warm-temperate. Sørensen similarity indices were used to
compare the marine algal flora of Iran with that of Saudi
Arabia within the Persian Gulf and the Sultanate of Oman
within the Gulf of Oman. The algal diversity of the Iranian
coast within the Gulf of Oman is less than that within the
Persian Gulf, and this difference is attributed to under-
collecting. Given that this is the first inclusive checklist
of macroalgae of Iran, covering the coast lying within
the Persian Gulf and the Gulf of Oman, it could serve as
a foundation for future phycological and biogeographical
studies of the taxa in the country and the region.
Keywords: Gulf of Oman; Iran; macroalgae; Persian Gulf;
Sørensen similarity index.
Introduction
Iran is a semi-arid country in southwestern Asia, extend-
ing from latitude 25° to 40° North and longitude 44° to 63°
East, with a large variation in climate from north to south
(Abbaspour etal. 2009). To the north, Iran borders the
largest closed body of water in the world, the Caspian Sea,
with a shoreline approximately 800 km long. In the south,
Iran has a coastline of approximately 5000 km lying
within the Persian Gulf and the Gulf of Oman (Dibajnia
etal. 2012), to which it is connected through the narrow
Strait of Hormuz. The Persian Gulf is a semi-enclosed and
evaporative marginal sea with a mean depth of about 35m
and dotted by many small islands (Hassanzadeh et al.
2011, Kourosh Niya etal. 2013). In comparison, the Gulf
of Oman is connected to the Indian Ocean and provides
direct access to open seas (Pak and Farajzadeh 2007).
Compared with those in the north, the water boundaries
in the south of Iran lie within the sub-tropical high-pres-
sure zone, and thus are characterized by low precipitation
and high aridity. Along this coastal area a variety of eco-
systems, such as mangrove forests, rocky shores and coral
reefs (Pak and Farajzadeh 2007, Abuzinada etal. 2008),
provide suitable habitats for seaweed growth (Figure 1).
Seaweeds or marine benthic macroalgae form a rather
heterogeneous group of primary producers, including
three major divisions based on the nature of their pig-
ments and other fundamental characteristics: Chloro-
phyta (green algae), Ochrophyta (Phaeophyceae; brown
algae) and Rhodophyta (red algae). Seaweeds are recog-
nized to be resources of high ecological and economic
value because they provide a wide assortment of bioactive
compounds that could be added to food, medicine, and to
biofertilizers (Hong et al. 2007, Dhargalkar and Verlecar
2009, Koch etal. 2013). However, there is no comprehen-
sive listing of the seaweed species that have been recorded
in Iran. Furthermore, knowledge of the marine seaweed
diversity of Iran is largely inaccessible to researchers
because most data are scattered in regional papers or
reports (often in Persian), and the recent checklist of the
Persian Gulf by John and Al-Thani (2014) covers only the
Persian Gulf coast of Iran. Therefore, the objective of this
study was to collect and update all the information on
macroalgal diversity in Iran in a comprehensive checklist
accessible to the international community.
History of seaweed study in Iran
The history of seaweed study in Iran dates back to 1845,
when Endlicher and Diesing reported the names of six
species of brown and red algae from Khark (also Kharg)
and Kish Islands in the Persian Gulf. In 1939, Børgesen
reported 77 species of marine algae from Kish Island and

Bushehr province. Several papers were published in the
20th century on species of marine algae in the Persian
Gulf, but most of them covered the Arabian side of the
Gulf (e.g. Nizamuddin and Gessner 1970, Basson 1978, De
Clerck and Coppejans 1996). Consequently, there was a
wide gap in records of Iranian marine macroalgae between
1939 and 1996, when Sohrabipour and Rabiei (1996, 1999)
published the very first checklist on the marine algae of
the Hormozgan province of Iran. They listed 144 species
of seaweeds, including 36 Chlorophyta, 33 Ochrophyta
(Phaeophyceae) and 75 Rhodophyta in the Persian Gulf
(Sohrabipour and Rabiei 1999). In 2004, Sohrabipour
et al. reported 119 species of seaweeds, including 29
Chlorophyta, 31 Phaeophyceae and 59 Rhodophyta in
the Persian Gulf, Lengeh area of Iran. Sohrabipour and
Rabiei (2007, 2008b) also published a checklist of 62 Chlo-
rophyta and 74 Rhodophyta from the Iranian coast of the
Persian Gulf and the Gulf of Oman. In 2011, Gharanjik and
Rohani-Ghadikolaei reported 150 species of Iranian sea-
weeds, including 39 Chlorophyta, 40 Phaeophyceae and
71 Rhodophyta.
Recent taxonomic studies on the seaweeds of Iran
have been conducted by Sohrabipour and Rabiei, on
Gracilaria (Rabiei etal. 2008) and Gracilariopsis (Bellorin
etal. 2008, Sohrabipour and Rabiei 2008a). In addition,
Shams etal. (2013) made the first reports of five species of
Sargassum from Iran.
The ecological features of Iranian seaweeds have been
studied to a small extent. In 2012, Fatemi etal. studied the
seaweed biomass from intertidal rocky shores of Qeshm
Island. The authors collected and identified a total of 73
species of marine algae from the southern and the north-
ern parts of the island. Dadolahi-Sohrab etal. (2012) noted
seasonal changes in seaweed diversity on the northern
coast of the Persian Gulf (Bushehr Province). Seasonal
variation in macroalgal assemblages was also observed
along the eastern coasts of Qeshm Island (Persian Gulf;
authors’ unpublished data).
Interest in studies of the potential economic impor-
tance of seaweeds has significantly increased in recent
years. The agarophyte taxa, especially the Iranian
endemic species Gracilariopsis persica, has received
more attention than other local seaweeds (Salehi etal.
2011, Saeidniaa etal. 2012, Matinfar etal. 2013, Yousefi
etal. 2013, Heydari etal. 2014). Aside from studies focus-
ing on the commercial potential of Iranian seaweeds,
some researchers have investigated the pharmaceutical
features of Iranian seaweeds to find novel medicines
(Zandi et al. 2007, Derakhshesh et al. 2011, Ghannadi
etal. 2013, Jassbi etal. 2013, Kokabi etal. 2013, Yousefzadi
etal. 2014).
Methods of checklist production
This checklist of the seaweed species of Iran is based
on an exhaustive bibliographical search in which both
local reports and international publications were con-
sulted for species records. All taxon names and their
classification were verified by reference to AlgaeBase

(www.algaebase.org) and updated when necessary (Guiry
and Guiry 2014). This website contains the latest taxonomic
and floristic publications on algae and the taxonomy and
nomenclature of the entries are updated regularly.
The checklist is arranged in alphabetical order of
families under three different algal groups, the Chloro-
phyta, Ochrophyta (Phaeophyceae) and Rhodophyta. The
species are also listed alphabetically under each family.
For some taxa, the taxonomic synonyms are presented
after an equal sign and references to the original publica-
tions are indicated in brackets as follows: Current name
and Author = Synonym and Author [Reference].
To determine the relative tropical or temperate affini-
ties of the algal flora, Cheney’s floristic ratio was applied.
This ratio is (R+C)/P, where R is the number of taxa of
Rhodophyta, C the number of taxa of Chlorophyta, and P
the number of species belonging to the Ochrophyta, Class
Phaeophyceae. The ratio characterizes the geographic
nature of an algal flora (Kaldy etal. 1995, Augytė 2011,
Augytė and Shaughnessy 2014). A ratio of < 3.0 indicates
a cold-water flora, whereas ratios of > 6.0 indicate a tropi-
cal flora; intermediate values represent a mixed floristic
affinity (e.g.warm-temperate; Kaldy etal. 1995, Witman
and Roy 2009).

Using Sørensen similarity indices (Magurran 1988,
Nguyen etal. 2013), the Iranian seaweed flora was compared
with those of the Persian Gulf coast of Saudi Arabia and also
the Sultanate of Oman (including the Gulf of Oman and
Arabian Sea coastlines of this country). These two countries
have longer coastlines along the Persian Gulf and the Gulf
of Oman than the other neighbouring countries (Figure 1),
and they are comparable with the Iranian coastlines from
the diversity standpoint. The floristic data for all neighbour-
ing countries were obtained from AlgaeBase and John and
Al-Thani (2014). A Sørensen index of 1.0 indicates complete
similarity (when the two sets of species are identical) and
0 if the sites have no species in common (Magurran 1988).
Results
Chlorophyta
A total of 78 taxa belonging to the Chlorophyta, within 15
families, are presented in this checklist (Table 1). The family
Cladophoraceae contained the most species (23), followed
by the Caulerpaceae with 12 species. Moreover, Cladophora
and Caulerpa were the most diverse genera among the
Chlorophyta with 13 and 12 taxa, respectively (Table 1).
Ochrophyta (Class Phaeophyceae)
To date, a total of 70 taxa of Ochrophyta (Phaeophyceae),
from 7 families, have been reported from the Iranian
coastline of the Persian Gulf and the Gulf of Oman
(Table2). The most diverse family among brown algae is
the Sargassaceae with 33 taxa, followed by the Dictyo-
taceae with 21 species. Furthermore, the genera Sargas-
sum and Padina have the most taxa (25 and 10 species,
respectively) among the brown algae of Iran (Table 2).
The species Ectocarpus cryptophilus Børgesen is rejected
here because it is recorded only once from Iran in 1970
(John and Al-Thani 2014).
Rhodophyta
A total of 161 taxa belonging to the Rhodophyta, within 30
families, have been reported from the Iranian coastlines
bordering the Persian Gulf and the Gulf of Oman (Table 3).
The most species-rich family among the red algae was the
Rhodomelaceae with 36 taxa, followed by the Gracilari-
aceae with 16 species. Furthermore, Gracilaria with 14 and
Hypnea with 10 were the most species-rich genera in the
Rhodophyta of Iran (Table 3).

Discussion
In a changing world in which anthropogenic impacts are
dramatically altering the biota of the Earth, the task of
discovering and documenting biodiversity has been given
an increased sense of urgency (De Clerck etal. 2013). This
paper is the most comprehensive checklist of marine
macroalgae for the biogeographic region that includes
the Persian Gulf and the Gulf of Oman coastlines of Iran.
A total of 309 taxa (78 Chlorophyta, 70 Phaeophyceae
and 161 Rhodophyta) are listed in this paper, compiled
from both regional and international publications on the
macroalgae from the coastal waters of Iran. The results
indicate that Sargassum (Ochrophyta, Phaeophyceae)
with 25 taxa was the most diverse genus, and that the
Rhodomelaceae (Rhodophyta) with 36 taxa was the most
species-rich family among the macroalgae of Iran.
Globally, the relative abundance of species of red,
brown and green algae varies depending on latitude
linked to sea temperature. The species richness of brown
seaweeds increases toward higher latitudes and colder
regions, whereas green and red seaweeds increase from
the polar regions to the tropics (in the northern hemi-
sphere; Lee 2008, Witman and Roy 2009). Based on this
information, the ratio of (R+C)/P and other similar ratios
(e.g. C/P) (Witman and Roy 2009) change with latitude.
In this study, the Cheney’s ratio of 3.4 for the Iranian
seaweed flora indicates a mixed algal flora with strong
cold-water affinity, but classifying the seaweed flora of
Iran as cold-temperate might be misleading. It is clear
that the reduction of species diversity of brown algae in
warm waters does not apply to all groups. The Dictyotales
(e.g. the genus Padina) (Witman and Roy 2009, Ni-Ni-Win
etal. 2011, Silberfeld etal. 2013) and some genera belong-
ing to the Fucales, such as Sargassum, are more species-
rich in the tropics, whereas the Laminariales, many other
members of the Fucales, and other brown algal groups
are generally more diverse in temperate or cold waters
(Witman and Roy 2009). Given this information, it is
important to consider the composition of brown seaweeds
when determining the climatic affinities of an algal flora
based on Cheney’s ratio. Given that 50% of the brown
algae reported from Iran belong to the genera Sargassum
and Padina (Table 2), we suggest that the seaweed flora of
this coastal region should be regarded as warm-temperate.
Because Iran has a longer coastline along the Persian
Gulf and the Gulf of Oman (5000 km) than its neighbour-
ing countries surrounding these two water bodies, it was
not surprising that the number of taxa reported for the
entire northern coastlines of the Persian Gulf and the Gulf
of Oman would be greater than that for the neighbour-
ing countries (Figure 2). However, the total number of
seaweeds reported from the Sultanate of Oman (223 taxa;
AlgaeBase) is greater than that of the northern coastline of
the Gulf of Oman (192 taxa). The Sørensen similarity index
between these two floras is also low (Cs < 0.5; Table 6).
These results indicate that the species composition of the
two areas is different, and this may be because the Sultan-
ate of Oman also has a shoreline on the northern Arabian
Sea. If it was possible to compare the seaweed flora of only
the Gulf of Oman coastline of the Sultanate of Oman, the
results might be different.
Although we cannot ignore the fact that the shore-
line of the Sultanate of Oman on the northern Arabian
Sea probably accounts for the higher seaweed diversity
in this country than in Iran (Wynne 2000), we are of the
opinion that the lower number of seaweed species on
the Iranian coastline of the Gulf of Oman and the low
similarity to neighbouring countries (Cs = 0.38) are prob-
ably the result of the relatively low number of taxonomic
studies, especially along the northern coast of the Gulf
of Oman. The lower number of species along this coast
than along the Persian Gulf coast of Iran (215 taxa) sup-
ports this idea. The Iranian coastline of the Persian Gulf
is bordered by three provinces (Khuzestan, Bushehr and
Hormozgan from west to east) with many academic and
research centres studying marine algae and other marine
organisms. In comparison, the Iranian coastline of the
Gulf of Oman is bordered by only one province (Sistan and
Baluchestan) with few research centres. After comparing
the number of publications on Iranian seaweeds along
these two coasts, it becomes evident that the marine algal
flora of the Persian Gulf coast of Iran is more intensively
studied than the coast of the Gulf of Oman. Considering
the less extreme oceanological conditions along the Gulf
of Oman coast of Iran and less urbanization (in contrast
to the Persian Gulf), it is very probable that many more
species are waiting to be discovered in this area.

As far as we are aware, this is the first inclusive list
of Iran’s macroalgal flora, and publishing it improves its
accessibility to the international community. Further-
more, the checklist provides some valuable regional infor-
mation about seaweed diversity, which could serve as a
foundation for future phycological and biogeographical
studies of the taxa in the country and the region.
