摘要：

The American lobster, Homarus americanus which usually has dimorphic chelipeds consisting of a cutter and a crusher claw, occasionally has bilateral crusher claws. In these unusual lobsters however, only one of the paired claw behaves as a normal crusher claw. The other claw has only the appearance of a crusher claw but behaves as a cutter claw being able to close its dactyl completely in 20 msec and having short‐sarcomere, fast fibers in its closer muscle. This suggests that claw morphology and closer muscle composition are not under rigid developmental control. Copyright © 1979 Wiley‐Liss, Inc., A Wiley Company
