Saccocalyx pedunculatus
No full textThe seabed at Kitatange-1 was dominated by soft sediment with occasional areas of hard substratum. The rocks supported sessile invertebrate assemblages such as sponges and soft corals. The images show a large hexactinellid (Saccocalyx pedunclatus)
Cod
No full textlarge numbers of cod, ling and coalfish were aggregated around the protective structure. Occasional cod were observed to feed on items on the structure.Cod on a protective structure on the seabed at Lancaste
Cod and sponge
No full textThe cod was feeding on crustaceans in the water column.A cod appeared as we examined the sponge with the ROV's video and stills camera. It was catching small crustaceans that were attracted to the vehicle's lights. The sponge resembles Mycale sp. Also note the numerous ophiuroids (brittle stars) on the sponge and the galatheid (squat lobster) in the foreground
Tripodfish
No full textSwimming above seabed.There are two very closely related species, B. viridensis and B. guentheri that occur mainly as geographic cognates, but co-occur in the eastern Atlantic off western Africa. They differ in the lateral extent and placement of the black color sections along the body (aside from other more technical details). In B. guentheri, the band under the dorsal fin is black (of total of two black bands). In B. viridensis, it is white (of total of three black bands), as in these images
Holothurian
No full textA holothurian on the seabed. This resembles Mesothuria sp. Note the foreign particles that the animal has placed over its body. The items on the body seem to be, shells, items of terrestrial plant material and foraminifera
Common Skate
No full textA brief encounter with this skate. The skate was on the seabed near some survey equipment as the ROV approached to recovery the gear. It began to swim away as it was illuminated by the ROV lights.Recently the Common Skate (Dipturus batis) was recognised as being two distinct species - with the Flapper Skate D. cf. intermedia being the more northerly (and larger) of the two, and the more southerly species being the Blue Skate which is likely to retain the name D. batis (scientific names are still being decided). This individual looks like D. intermedia and that fits with the distribution and where it was sighted.
The "common skate" is, in fact very rare. It is classified as critically endangered by the IUCN red list of threatened species http://dx.doi.org/10.2305/IUCN.UK.2006.RLTS.T39397A10198950.e
Ctenophore
No full textCtenophores are characterised by rows of cilia that beat synchronously and can be seen in these images as they reflect the ROV lights
