Got a picture? The mole crabs sold in LFS are usually temperate water sand beach animals. They live half-buried in the highly-oxygenated swash zone...
Gresh's cavalry is here. ;) It appears to be an asterinid star which means it belongs to the family Asterinidae. They are extremely difficult to...
Not at all. The worst that can happen is that you'll have lots more spionids to join your clean-up crew.
Yes. The bubble is an egg mass. Inwall made a good guess when he said spionid. If it isn't a spionid it's at least something related. Would you...
If it really looks like that it's most likely a sphaeromatid. Did you catch them? See if they can roll up into balls. If so they are sphaeros...
Crabs often have things like algae, sponges, bryozoans, tunicates growing on them. Since your crab is missing a couple of legs it's probably having...
The thing about web id sites and even the published guides is that they all have mistakes. The best only have a few but some sites are so bad it's...
Hi 2in10 - got your message. It sure isn't an emerald. There are a lot of families that have been split off the Xanthidae in recent years and your...

It would be more accurate to call it an asterinid which means it belongs to the family Asterinidae. Asterina is just one genus in this family....
Was it actually feeding on the duster or just moving it? Eunicids are big landscapers. They camouflage the opening of their burrows or build...
Yeah, it's hard at first but after the first 500 or so you get an eye for them LOL
Sure it was that particular one? There are probably a couple of hundred species in each family.... :) But you're right, they are very cool animals!
Ah...er...ahem....sorry..... It's easy to be fooled with these guys. It's not a spagetti worm. Those are in the polychaete family Terebellidae....
Aiptasia reproduces very rapidly by splitting off clones - that's what makes it a devastating pest in reef tanks. They also seem to be able to...
It seems to be Dendrodoris fumata which is common in the Indo-Pacific. There's a very similiar one called Dendrodoris nigra. Both have quite...
