Actinoscyphia sp.

Actinoscyphia sp.Actinoscyphia sp.

Description

Actinosyphia sp. can modify its base to grasp structures upon which it attaches. It was found attached to rocks here. It was uncommon during field work off Tanzania but observations at 1370 m and 2400 m suggest it is likely to be found throughout the study area. There is discussion in the scientific literature about this animal’s taxonomy. The group it belongs to have structures called acontia, thread-like extensions rich in stinging cells (nematocysts). These are absent from Actinoscyphia sp. and a few other species in the group. Genetic evidence supports its affinity with the acontia bearing species and it is suggested that they have been lost in this species.
