Where are you going to collect them? Are they ball shaped and smooth, or bumpy? Are you going to collect them off rocks or in the sand? If you can...
You can try to catch him when you see him again, or you can take out any likely polyps and see if you see any more hiding amongst/under them? The...
It might be a gall crab, and you're looking at its rear end?
They say there is a worldwide shortage of sponge taxonomists, and most of the dozen or so experts are bald from pulling all their own hair out......
The snail is actually a Collonista snail, in the Turbo family. They are algae grazers like the trochids, though. Cheers, Don
Well, the first rule of slug and snail photography is that they all look the same from the bottom, LOL. Of course, you'll remember that next time,...
The green serpent stars, AKA "Green Death," are widely known to be occasional killers. I also had a red one that looked similar and was a killer,...
LOL When you're in that situation, you figure you have to do something, even if all the options sound like bad ideas... A couple years ago I was in...
I blew up the pics and clarified them as best I could, and can tell that it's definitely not a chiton, but I can't say for 100% fact that it's a...

No es un barnacle, it's a Crepidula, Crepidula fornicata I believe. Linnaeus name 'em that because they are often piled one on top of the other, and...
I don't think they're spirorbids, and I'm pretty sure they aren't Collonistas either. There are a bunch of little almost-transparent snails in the...
Yes, it's a Polyclad Flatworm, not to be confused with the harmless or annoying acoel flatworms. These are very capable snail killers, and some of...
Yep, they are absolutely not sundials. They are absolutely in the family Turbinidae, subfamily Colloniinae. Whether this species turns out to be...
That's interesting. It's the same species, but that one is an adult. My big ones never climbed the walls...I wonder if he's trying to reach the...
Hi, I'm here, lol, Yes, it's a keyhole limpet, which isn't exactly the same as the true limpets, all of which are algae eaters. Most of the ones...
Thanks for the pics. Those are Strombus (Conomurex) luhuanus, also known as a Strawberry Conch or a Red-Mouthed Conch (I guess neither of which is...
