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 
e.g. at Scripps intitute of
oceanology might have more insight than I have.
I hope this helps you a bit,


kai bester
