Unkown Critter from the Bay Islands in Critter Identification Posted June 13, 2005 I just did a websearch - these guys are very cool! Apparently some species are "farmers" who collect & store seagrass & algae within their burrows in special chambers. As the seagrass decays the shrimp eat it. Judging by its burrow construction & behavior it might be Corallianassa longiventris which is widespread in the Gulf of Mexico & the Caribbean. Researchers have reported that it's easy to lure individuals of this species partially out of their burrrows by holding blades just out of their reach.
