Abstract
The hypothesis of a locomotor role for the free rays of Trigloporus lastovi za is supported by: (1) their periodic retraction and protraction during sl ow displacement over the substratum whenever the propulsive body wave respo nsible for swimming is not visible; (2) the integration of the rays' indivi dual cycles into a hexapod gait apparently generated by a metachronal impul se; and (3) the kinematic features of the longest free ray in relation to t he bottom-walking velocity.
