quick sketch of the Manocherian's catshark (Apristurus manocheriani) to redeem my cursed past... Finally, a somewhat proper illustration of this species! #shark #sciart #digitalart

For World Squid Day, here's a gorgeous Moroteuthopsis longimana! International cephalopod awareness days happen each year in Oct — we celebrate octopuses on the 8th, in honor of their 8 arms, & squid on the 10th, to acknowledge their ten appendages (8 arms & 2 tentacles).

Our #CorpsofExploration witnessed this #CasperOctopus from the suborder Incirrata while exploring a series of knoll hills in the central region of the #CookIslands' waters while diving #ROVLittleHercules over 4,100 meters (13,000+ feet) deep.

We encountered this #BigfinSquid (genus Magnapinna) over 5,100 meters deep while exploring the abyssal plain in the waters of the #CookIslands. They are rarely ever seen by humans and are the only squid known to live as deep as the hadal zone.

Is it a butterfly doing a backstroke? You may not know it, but this deep-sea #isopod is a rare sight! Scientists still have much to learn about the long-limbed crustacean #Bathyopsurus, as only a few specimens (of only two species) have been collected.

BOO! 👻🎃👻 No costume for Halloween? No problem. Channel your inner sea urchin: go into your closet (or sunken treasure chest), & throw on all the outfits at once! A few clams, some snails, & carnivorous sponges for drama ought to help keep your fellow partiers in high spirits.
