Introduction
I am an marine biologist with an special interest in benthic invertebrates. Currently I am working for my PhD thesis with meiobenthic organisms, in particular with the interstitial cnidarian Halammohydra. For this study I use morphological and molecular methods, like transmission electron microscopy and DNA sequencing of 16S and 18S genes. The aim is to detect potential cryptic species in this genus with the backround of the overall speciation in the interstitial system.

Meiofaunal cnidarians are less represented in the interstitial system compared to other groups. The largest genus is Halammohydra Remane, 1927, a modified medusa. Together with another medusa of the genus Otohydra Swedmark & Teissier, 1958 they classically form the taxon Actinulida. Due to major morphological differences, this relationship is in qu...
Whereas most cnidarians are macrofaunal, a few microscopic lineages have evolved, and some of them inhabit marine sediments. The meiofaunal genus with the most species is Halammohydra , comprising nine nominal species. Species are described with high intraspecific variability in, e.g., the number of tentacles and statocysts and the shape and length...
Within meiofauna, cnidarians are represented by only a few species most of which are in the genus Halammohydra Remane, 1927. It represents highly modified medusae. Information about this group is limited, which complicates its placement in the Cnidarian tree and the relationship to another meiofaunal cnidarian, Otohydra Swedmark & Teissier, 1958. T...
In July 2019 an international team of 39 senior and junior researchers from nine countries met at the University of the Azores in Ponta Delgada, São Miguel for a 10-days workshop/summer school to explore the meiofaunal biodiversity in marine sediments of
the Azores. In total, we sampled intertidal and subtidal sediments from 54 localities on 14 ma...
One of the most diverse interstitial cnidarian genera is Halammohydra Remane, 1927. The hydrozoan of the order Actinulida was recorded before in Europe (i.e., Germany, Norway, France), India and the West Atlantic. This is the first record of Halammohydra from the Azorean islands. Specimens were collected at different stations from sandy
sediment du...
