Actinoscyphia sp.
No full textTwo animals shown. One is open, the other closed. Also note the decapod crustaceans hiding under the rock.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

Platylistrum platessa
No full textWith no hesitations - Platylistrum platessa Schulze, 1904 (Hexactinellida, Amphidiscophora, Pheronematidae). Common at the Kamba and Pweza site
Chrysogorgiidae
No full textProvides habitat for chirostylid squat lobstersThere are more than 60 known species of Chrysogorgia and species identification requires examination of sclerites and other anatomical features not visible in the images. The image shown here was collected at Kamba-1 and a similar specimen was seen at Pweza-3, both sites are in Block 4 offshore Tanzania at approximately 1380 m water depth. In each case the coral provides habitat for chirostylid squat lobsters
