Two common marine animals of the South Atlantic and Gulf coasts, Sicyonia brevirostris, a penaeid shrimp, and Opsanus beta, a toadfish, may be induced to go into cataleptic states in the laboratory when they are threatened or molested. The behaviors of these two animals as they go into catalepsy are described. There is considerable paling in the fish but none in the shrimp.
