    Cool Pics

    Copepods You can trust my friend Art to get the coolest pics of small critters! This one is especially nifty. These are commensals copepods that were living on a pistol shrimp collected somewhere around the island of Moorea in French Polynesia. Small males hitchhike on larger females. The...

    Looking for a coco worm ID?

    Ayup, vermetid snail. From the description it sounds like one of the larger species that don't spread in tanks - which is good. There's some very common small species that are capable of taking over pretty much all the available hard substrate.

    Regulating worm numbers

    I usually don't worry about getting rids of worms so I checked with some veteran reef keepers & went through a number of old threads for non-wrasse choices. The filefish Acreichthys tomentosus was highly recommended. In their experience it's a voracious eater of bristle worms. As an added...

    Acropora Eating starfish

    Hi all -- I really think we need to stop using the name Asterina. As of a couple of years ago there were 26 genera in the family Asterinidae. I tried to identify some specimens & got hopelessly lost due to the complexity of the characters used to separate the genera (which could be saying more...

    Strange Worms

    O. incrassata is always green. The brown one you saw could still be an Ophiarachna but a different species. There are so many animals it's hard to keep them straight!

    Might have gotten a bad Peppermint shrimp

    It's true, crustaceans are usually the first suspect when something goes wrong. When mild-mannered shrimp & crabs don't behave the way they're supposed to there are several reasons. One is that the animal was badly identified from the start - like the red fiddler crab that was being advertised...

    Strange Worms

    It is hard to tell from a picture showing just arms however the dreaded Ophiarachna incrassata is solid green in color and does not live in the rocks like that. Yamaha's brittle stars could belong to any one of numerous rock-dwelling detritus-feeding species.

    Commensal Birdsnest Pistol shrimp? ID pics for you, Leslie

    I really don't know. Reefers have reported that their commensal crabs like Trapezia seem to do fine without their hosts, maybe the shrimp would do.

    Commensal Birdsnest Pistol shrimp? ID pics for you, Leslie

    Thanks, Brie. Your post is the ideal ID request - what you want to know about, where it came from, and excellent pics! Those are part of the Alpheus lottini complex. It has a very wide distribution in the IP, WP, and EP. Members of the complex have a variety of color patterns which can be...

    Semi-Terrestrial Crabs?

    Hi Algae -- sorry for the delay. I'm currently at a small marine station in the US Virgin Islands and my internet access is sporadic. Semi-terrestrial crabs aren't found on reefs so that's kind of a problem. If you got one you'd need to supply it with a place to haul out like a sand/mud...

    Cool Pics

    The fire urchin is gorgeous but it's the other one that's really interesting. See those snails? They're in family Eulimidae. All the members of the family are specialized parasites. The ones in the pic might be an Echineulima - the "echin" in the genus name means they prey on echinoids, aka...

    Cool Pics

    Okay, here's another very cool invert, the Triton's Trumpet, Charonia tritonis. photographed by G.J. Reclos More photos & text on the Malawi Cichlid Homepage Charonia tritonis Why is this cool? It's beautiful to begin with, huge (way too big & destructive for most tanks), can be used as...

    Holiday video from Vancouver Aquarium

    Just explain to your little girl that Christmas is over so you can't decorate the tank. Watch out for Easter though when she'll want to give all the fishies candy & easter eggs - the bioload will be the real problem!

    help id this snail?

    I think it's more likely to be a Mitra, maybe Mitra papalis. This species is a specialized predator on worms - mostly sipuncs (peanut worms) and other small inverts. There's a great discussion of their feeding habits on Christopher Taylor's blog Catalogue of Organisms. Mitra (Tiarella) papalis...

    White tiny critters on glass Help?

    I suspect they're either tiny jellies or pods. If they sit in one place &"pulse" - expand & contract - they're jellies. If they skitter around they're pods - small crustaceans which are primarily micro-grazers & predators on other tiny organisms. Take a look at the first photo on the left...
