Eel
No full textSwimming above seabed.Halosauridae, or genus Halosaurus (single median dorsal fin, anal fin tapering to a fine tip). The snout tip is rounded and a bit inflated, consistent with genus Halosaurus, as opposed to the otherwise similar genus Aldrovandia
Lithodid Crab
No full textFeeding on bait on the seabed.1000 – 1500 mm maximum dimension. Seen attracted to tuna
bait. It is either of the genus Lithodes or Neolithodes
(although sadly the distinguishing feature is on the
abdomen which is not visible). Two likely candidates are
known from this region – Neolithodes asperrimus or Lithodes ferox. Unless the video distorts the secondary spines (which should cover N.asperrimus), it is most likely to be a Lithodes ferox with a malformed or regenerating rostrum
Long-nosed Chimaera
No full textSwimming in the water column.Over 1000 mm length. A Rhinochimeridae, looks like the genus Harriotta, but this is tentative
Snub-nosed Eel
No full textFeeding on a carcass on the seabed.800 - 1200 mm length. Family Synaphobranchid ae. This is the species Simenchelys parasitica, which behaves much
like a hagfish. It has a very muscular head with a small
mouth, used to rip flesh from a carcass
Hydroid Corymorpha glacialis
No full textAttached to seabed. Probably feeding.Identified by Peter Schuchert. Identifying the two specimens was initially rather difficult. Both polyps, but
especially the larger 008#4, has a polyp body which shows some bilateral features, viz the outline seen from below
is kidney shaped. This is otherwise typical for the related genus Branchiocerianthus. However, other diagnostic features of the genus Branchiocerianthus are
absent:
branched blastostyles (stalks bearing the gonads), blastostyles arranged in a horseshoe- shape, shorter
tentacles on one side of the hydranth.
So, I think that the kidney-shaped bodies are a result of the large size. Note that the polyp body is bent to one side in order to bring the tentacle crown to an almost vertical position, one side of the body and the lower tentacles are thus pressed against the stem. With age, these might therefore be modified Besides the body form, only the size deviates from existing descriptions of this species. In the original description of Sars, he gives a size of maximal 5 inches, which is not so much different from the present specimens. Likely only specimen 008#4 is larger than 5 inches. The size of animals I have seen so far was 4-5 cm. Anyway, I will mention these two specimens as deep water forms of C. glacialis (normal occurrence is 20-220 m). Corymorpha glacialis is a rather rare species and only a handful of specimens have been seen so far
Cancer pagurus
No full textFeedingCancer pagurus attracted to a bait on the seabed. The white measurement tags are 100 mm apart
Monkfish
No full textWaiting for preyA monkfish lying in wait on the seafloo, Lophius piscatorius were found on average with a density of 0.00 individuals per metre squared at Lancaster
Seastar (ophiuroid)
