Fresh Water Shrimp

Macrobrachium hancocki

Description:

I saw this river crustacean in a pond at the base of a small waterfall in a stream in tropical rainforest. It was 3 - 4 inches long with bright blue claws and one very oversized pincer. Couldn't get a very good photo through the water.

Habitat:

pool in a tropical rainforest stream

Notes:

I have moved this from fish to the correct category of arthropod.

that's an Arthropod Lisa !? Thank you... I would never have placed it there. Live and learn.

I said the part in the U.S. Other parts call them other things.

The part about most of us call them shrimp is not familiar to me. We call them Crawdads. Ones without claws and are not lobster type are shrimp and other then brine shrimp are not freshwater.

Jellis, have a look at this... The bit about Macrobrachium carcinus in Costa Rica.

Hmmm jellis... Maybe the English name is incorrect then. The link is in German. http://www.wirbellose.de/arten.cgi?actio.... and this is Larry's spotting with many comments

Only thing is I don't believe shrimp have claws.

thanks Larry, I just came across your spotting of one of these - though I fared even worse than you with clarity - but now I know what it is. Thanks to Alexander M Kim for the ID.

Yes, maybe Mark. I only said oversized because there were other transparent crustaceans in the stream, smaller, but 2 small claws. They looked more like shrimps.

Maybe this. It's only I see mention blue.

Nice find Pam. Could it be one very undersized pincer? ;-)
