Re: Worm ID help needed

Hi David, Your worm does appear to be a terebellid (aka spaghetti worm) but it doesn't look quite right for the most commonly seen local terebellid Thelepus crispus . I didn't have much luck but if you do a really persistant image search on Google or Bing you could get lucky. It's pretty unusual to ...

Re: A question about alabaster nudis . . .

Hello again, Unlike with many nudibranchs, defining the diet of this species is fraught with difficulties since they seem to be willing to eat whatever is available and within their abilities to capture. Here's a link to a paper describing them eating snails: http://scholarspace.manoa.hawaii.edu/bit...

Re: A question about alabaster nudis . . .

Hello, I'm assuming that you're referring to Dirona albolineata . If that's the case then it most likely does not sequester nematocysts in the manner of the aeolid nudibranchs. Acccording to The Sea Slug Forum this species mainly eats bryozoans and other almost exclusively non-stinging prey. The sit...

Re: Redondo ID's?????

Hi Kathy, I'm going to respectfully and tentatively disagree on the anemone ID. The fat tentacles and lined oral disk make me thing it's a stubby rose anemone aka Urticina coriacea . Not being a diver, I'm not familiar with conditions at Redondo but one would expect to see this anemone mostly buried...

Re: How do shrimp find food?

Greetings, The line between taste and smell is pretty blurred for aquatic critters. That said, shrimp have a very well developed chemosensory ability with what amount to 'taste buds' all over with concentrations on the antennae and feet. Some shrimp also have quite effective eyesight (at least for a...

Re: Big Skate

Great find! Can these sting you like sting rays? Nope! The area of the skate's tail that corresponds to the sting area on a stingray is occupied by a bumpy longitudinal ridge (which is visible in the photos). Bigs, at least youngsters like the one pictured, do sometimes flail their tail around as i...

Re: Is this some kind of nudi?

Hi Tim, Gumboots, like other chitions, use their mucous lined foot to adhere very strongly to solid surfaces. My sense is that gumboots don't grip quite as tightly as other chitons on a pound for pound basis; also gumboots seem to be willing, if not eager, to venture onto sand at times. As to flippi...

Consider that the scientific name for this beast is Crypto chiton stelleri and that crypto means 'hidden'. As an aside, ' stelleri ' honors Georg Wilhelm Steller; a German scientist best known for his wo...

Hi John, I think your animal is a sedentary polychaete. At the Feiro Center we have some critters, that look very much like yours, growing on some empty rock scallop shells. From a distance (for me that means a foot or more) it looks like the shell in question is moldy; a closer look reveals individ...

Re: Gunnel ID help

Hi Kelly,

I'm voting for Slender Cockscomb based on the stripes under the jaw. Also, I think the eye bars on the High Cockscomb are more diagonal than the ones in your excellent photo. :stir:

Hi BillyD, I'm no expert but that fish looks to me to be a Red Irish Lord. The eyes appear larger and wider set than a Buffalo Sculpin; also the snout looks a bit longer and more tapered. Finally, according to Andy Lamb, this is a little early in the season for a Buff to be guarding eggs but it's ju...

Hi Dave, The octopus in your video appears to be O. rubescens so I'm basing my guesses on that. I'm not so good at estimating size but, unless you've got really big fingers, that animal looks too young to be mating (insert joke about today's kids here). My books indicate that O. rubescens maxes out ...

Re: Need help identifying a large worm

Hi Dave, If your worm was 30" long it would almost have to be either Nereis brandti or N. virens . If it was 12" then you could include a number of other possibilities: N. vexillosa , Phyllodoce spp., Glycera americana , or Nephtys spp. (which could be described as looking 'fluffy'). One o...
