OH I LOVE THIS!

Slow glide. Take it easy. 😎⁠

⁠This little squid, Abraliopsis (Boreabraliopsis) felis was captured on camera by the remotely operated vehicle (ROV) Doc Ricketts in the Monterey Canyon at 362 meters (nearly 1,200 feet). These squid frequent the California Current and have been observed by MBARI researchers swimming with their tentacles interlocked (as in this video clip). They typically stay in deeper waters (300–600 meters or about 980–1,970 feet) during the day, and move upwards into shallower waters (less than 100 meters or about 330 feet) at night.

When your ROV catches a squid doing the Karate Kid kick. ⁠🥋🦑 ⁠ . This species of Gonatus squid is one of the most common squids we see in the deep midwater. These squid grow rapidly, are active swimmers, and have among the highest metabolism of all cephalopods (octopus, squid, cuttlefish, and nautilus). They only spawn once in their lifetimes, and after the female successfully broods her single batch of eggs, she dies. ⁠ ⁠. This animal is striking a defensive pose at the approaching ROV. Remotely operated vehicle (ROV) observations of these squid in their natural habitat have enabled scientists to learn a great deal more about their behaviors.⁠ ⁠.

Uncle Tim at the Carnegie giving us those sweet snail facts!

How to Wear Your Shell: Snail vs. Monoplacophoran

Do you wear your baseball cap with the brim in front or in the back? For some headgear, the orientation matters, for example, a football helmet worn in non-standard orientation might hinder your ability to see.

In most snails (gastropods), the shell coils over the tail. In some other mollusks, the shell coils over the head.

Torsion is a feature of all snails. Torsion is a 180° twisting of the head-foot with respect to the shell and internal organs, early in development. Torsion results in the anus being over the head (snails are real poop heads!). Why snails are torted remains a biological mystery, but a common hypothesis is that torsion also brings the gills and sensory organs to the front, and the anus just came along for the ride.

Snails have muscles that attach their bodies to the inside of their shells. Snails tighten these muscles to pull the body into the shell. A consequence of torsion is that the muscle scars (where muscles attach to the shell) are asymmetrical.

Monoplacophorans are a class of mollusks like snails except they do not undergo torsion. The lack of torsion means the shell coils over the head (in those having coiled shells). Furthermore, the muscle scars on their shells are symmetrical. Few monoplacophorans survive today, but they were more plentiful millions of years ago.

When I see snails in the funny pages in the newspaper, I notice that the cartoonists drew the shells in the standard orientation about half the time (50%, or random chance). When you see a cartoon snail with its shell in a non-standard orientation, you might wonder if it is really a monoplacophoran?

Next time you put on your baseball cap, think about how snails wear their shells, and remember the famous baseball snail: Slicky Mantle – he was quite a slugger – you should see him slide into home plate!

#molluskmonday Gymnodoris rubropapulosa is a cannibal #nudibranch it follows the trail and smell of other nudibranches and since it is much faster than most it can reach them in a short time. The nudi grows up to around 65mm in length.

Mollusk Monday: Greater Argonaut

The Greater Argonaut (Argonata argo) is an octopus that creates a thin shell around it, resembling the nautilus, another group of mollusks in the Mollusca phylum.
