Abstract
IT is known1,2 that differences in sea water which are presumably of a biological nature affect the development of larvae of several marine animals, and it has been suggested by Lucas3–5 that “ectocrines” or “external metabolites” released by animals into the surrounding medium may so modify the environment as to make it either suitable or unsuitable for the survival of other organisms. The effect of such conditioning of sea water by adult sessile animals on the development of larvae has not been investigated so far and would be of interest in connexion with the “larval settlement problems”1.
