Early developmental sequences of Aratus pisonii (H. Milne Edwards) ( Brachyura, Grapsidae) under laboratory conditions.

Abstract:

The larval development of the mangrove tree crab can exhibit 3 different sequences when reared under different salinity conditions. Such sequences consist of the suppression of 1 and occasionally 2 zoeal stages prior to metamorphosis. Adoption of any particular development sequences is interpreted as a tendency to increase fitness through developmental plasticity, consequently as an evolutionary trend of the species towards an optional reduction of its pelagic life.-from Authors
