Abstract
The thickness of the ventral body wall of the sea lamprey (Petromyzon marinus) increased 117% from June through January, and decreased 14% from January through May. During these respective periods, length increased 93% and decreased about 11%. Our studies suggest that the loss in length is part of the natural cycle; possibly prespawning adults cease feeding, or feed at a greatly reduced rate, beginning as early as January, rather than in March or April, as previously believed.This publication has 0 references indexed in Scilit:
