Clathrozoella medeae
General description:This species is dedicated to Medea Peña Sancho, daughter of the senior author.
Diagnostic description:Branching sparse and irregular.
Stem cylindrical, formed by the fused basal parts of irregularly arranged pseudohydrothecae*, cemented together by development of perisarc.
Pseudohydrothecae curved upwards and outwards, with a long free portion; aperture circular, rim even.
Nematothecae finger-shaped.
Hydranths with 10-12 tentacles. Up to four ovoid gonophores per pseudohydrotheca.
Cnidome composed of microbasic mastigophores, microbasic euryteles, atrichous haplonemes and desmonemes.
*The hydrothecae in Clathrozoellidae have a structure differing from those of Leptothecatae and are here described as ‘pseudohydrothecae’.
Distribution:Clathrozoella medeae was collected from 128 to 630 m depth off Low Island, at Elephant Island, and east off the South Orkney Islands, in January, March and April.
