Textbook Question
Chapter 30, Problem 17TYK
An earthworm’s body consists of a number of fluid-filled compartments, each with its own set of longitudinal and circular muscles. But in the roundworm, a single fluid-filled cavity occupies the body, and there are only longitudinal muscles that run its entire length. Predict how the movement of a roundworm would differ from the movement of an earthworm.

c
Contracting longitudinal muscles which puts pressure on the hydrostatic skeleton and causes it constrict and elongate
d
Simultaneous contraction of longitudinal and circular muscles within a segment
e
Alternating contraction of longitudinal muscle in a posterior segment with contraction of circular muscles in the neighboring anterior segment
