senoritafish: (That's Ms. señoritafish to you!)
[personal profile] senoritafish
Haven't posted a new fish in a while. DP found this in a load of sardines. She was thinking it was odd since it was so truncated, with those strange round fins, and that there was only one of them - small squid are often in schools.

This view is actually the ventral surface; you can see its siphon, which it uses for jet propulsion and for digging holes to bury itself, along with the rounded fins for slower movement.

We did not know what it was immediately, but as I was staring at my screen, cogitating, I remembered hearing the name "stubby squid" and did a search on it. Where I first heard it, I don't remember - maybe somewhere in [livejournal.com profile] molluscious? - but lo and behold, this was one of the first sites to pop up:

Cephalopod Page: Rossia pacifica

They are also called bobtail squid, and really are more related to cuttlefish. The reason there was only one is they are fairly solitary. They range from southern California around the rim of the Pacific to Japan. They are, surprisingly, found in highly polluted bottom sediments like the Tacoma and Seattle harbors.

These little guys are so cute! I would love to see some live ones at some point.
