Definition: muscular waves propelling an animal over a mucus layer overlaying the substrate; alternating regions of muscular contraction and expansion create traveling waves that shear the mucus, resulting in translation of the animal.
Definition: Lecithotrophic larvae are provided with a source of nutrition to use during their dispersal, usually a yolk sac. They generally have greater dispersal potential than direct developers, but short pelagic larval durations relative to planktotrophic larvae.
Definition: Capable of creating a new organism by combining the genetic material of two gametes, which may come from two parent organisms or from a single organism, in the case of self-fertilizing hermaphrodites.
