Dear Laureen! Probably they do. Thopugh I am not familiar with sanddollars other marine organisms do communicate. Especially to co-ordinate spawning animals like those communicate via signal compounds which they do emit into the water while the other individuals detect these compounds and act accordingly. Complex hydrocarbon mixtures (as in crude oil) sometime interfere with this communication. I fear the research on this topic is still quite young, but marine biologists e.g. at Scripps intitute of oceanology might have more insight than I have. compare: http://www.sio.ucsd.edu/ http://dir.yahoo.com/Science/Earth_Sciences/Oceanography/Institutes/ Scripps_Inst itution_of_Oceanography/ I hope this helps you a bit, Cheers kai bester
