Clathrozoella drygalskii
General description:Branching frequent and irregular, branches long and flexuous.
Pseudohydrothecae* alternately arranged in one plane, each pseudohydrotheca inserting approximately halfway along adcauline side of preceding one, cylindrical but strongly curved outwards, forming two longitudinal rows. Each pseudohydrotheca in contact with two others; aperture circular; rim even. Branches originating on distal half of free adcauline pseudohydrothecal wall.
Nematothecae finger shaped. Hydranths with c. 10 tentacles. One ovoid gonophore 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 drygalskii is known from the southern part of the Pacific Ocean. It has been reported from the Davis Sea, in Antarctica (Vanhöffen, 1910) and off New Zealand and the south-eastern part of Australia (Vervoort & Watson, 1996).
