Bristle Bearing Octopus

Coral Sea, Duration 16 seconds

Kattegatcentret Grenå

Octopus punctatus.

Description: I think it is Eledone cirrhosa, this is partly because of the distribution (Clair Ridge is fairly shallow and ‘warm’ water), but also because of the pale coloured ridge around the edge of the mantle, yellowish colour and because it looks like it has one row of suckers (although this is basically guesswork from the image quality). Bathypolypus and Benthoctopus have a double row of suckers widely spaced on each arm and tends to live in deep-water (Benthoctopus piscatorum is known from 1400-2520 m depth in the Rockall Trough and Faroe-Shetland Channel) . Benthoctopus is also usually smooth and red/purple in colour. Benthoctopus piscatorum has arms approximately four times the mantle length, which is not consistent with the images.

Description: This one is a Muusoctopus (the new name for Benthoctopus). It is not Muusoctopus januarii and certainly not Pteroctopus tetracirrhus. It might be a Muusoctopus johnsonianus but they are usually paler that this with more distinct reverse countershading. I suspect that there are undescribed species in the Gulf of Mexico and this may be one. Octopus with 2 rows of suckers on each arm and 8 arms. This narrows it down a bit. It is a female as no reproductive arm (hectocotylus) is visible on the third right arm. An old reference on the recorded deep-water octopus from the GoM (Voss, 1956) seems out of date compared to modern knowledge.
