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.

Description: 12 tentacle anemone.
The animal is Halcampa arctica (sometimes confused with/possibly synonymous with H. duodecimcirrata).
It is not an Edwardsia—it’s a member of another family, Halcampidae. Both groups are burrowers, so this confusion is common.
The identification in Jones and Gates 2010 is incorrect.
