Hi guys - Rick emailed me about this one. It's a pelagic snail that's actually fairly common. In our area it's probably Carinaria japonica. More info here - Carinaria japonica

Opistobranch - Navanax inermis. You'll find more info on it at The Sea Slug Forum - Navanax inermis

Everything pelagic sinks eventually. It may even be part of the development cycle that the egg mass sinks before the hatchlings emerge.

It's clearly an egg mass & possibly from the diamond back squid Thysanoteuthis rhombus - look at the bottom of the page here Thysanoteuthis rhombus

It appears to be Pseudobiceros uniarborensis.

Hi guys -- Yes, it's a polychaete in the family Onuphidae. Platynereis is in another family, the Nereididae. I've seen some spectacular pics of this particular beast but unless I can put one under a microscope there's no way to get a genus or species name on it, sorry! It's rare that...

Anyone got a collecting permit? Gordon Hendler, our echinoderm curator, would be quite happy to have a specimen (legally collected, of course) to examine and confirm the id. One of my contacts did mention what he considered the remote possibility that it was Luidia guildingi which occurs in...

Locals have responded. It's a color variant. You can sorta see the reddish tip on the arm on the left - that's a good clue and as one of my friends said, L. columbiae is notoriously variable in color.

I'm at the Natural History Museum here in LA. Let's see what the local guys who know the fauna here say about the beastie.

It seems to be a color variation. Here's an image of another one http://diver.net/picture_on_black.shtml?diver.net/californiadiveboats.com/Peace/2006.07.03-04/P7037251clr.jpg If you don't mind I'll send your pic to our echino curator & see what he says.

No, it's not any type of worm. How was it moving? On it's own or with the current? Because to me it looks like a seed pod or type of vegetation.

It most certainly is a polychaete, AKA bristle worm (polychaete is a latin term that means many bristles). If you can take close up shots of the head & body parts I can give you more information on what kind it is.

Nearly all marine animals have been described from dead, colorless animals. Until I can examine a specimen I don't know if it's already described but the color pattern is unknown or if the animal really is undescribed. Incidentally, describers don't name species after themselves. They can...

Very interesting, thank you. Another new species to learn about!

Hi Rick -- It's a fireworm, family Amphinomidae, genus Chloeia. I haven't been able to determine if the species has already been described or not. That characteristic pigment pattern on the back probably fades away once the animal is dead. Without the pattern it's nearly impossible to match...

Yup, and the species Donny mentioned.

Without a picture your best bet is to search through the images on the Jellies Zone - a website dedicated to all things pelagic & gelatinous The JelliesZone - Jellyfish & Other Gelatinous Zooplankton

1 - Family Palaemonidae, subfamily Pontoniinae. Most of the commensal shrimp are in this subfamily. Genus Anchistos or Paranchistos. 2- Possibly Family Processidae, maybe genus Processa. 3 - I'm with Vie on this one. 4&5 - Another Pontoniinae, maybe a Periclimenes. 5

first one's not a spider - the body is too square and the last pair of legs is flexed up over the body. Probably a carrier crab in the family Homolidae. Looks very similar to the genus Latreillopsis. Second - sponge crab, Dromidae. There are a lot of genera and species most of which have...

There's a lot more lobsters out there. Check out this document - it has the names of every lobster for the area & descriptions/comparative figures for the commercial ones. ftp://ftp.fao.org/docrep/fao/009/ad468e/AD468eOB.pdf
