Variation in the Polytypic Sea Urchin Lytechinus Variegatus (Lamarck, 1816) in the Western Atlantic (Echinodermata; Echinoidea)
Abstract:Color, meristic, and morphometric data are given to show the morphological differences between the nominal subspeciesof Lytechinus variegatus. The greatest difference is in test color. Number of interambulacral plates, number of primary tubercles, and thickness of the primary spines also indicate differences between the subspecies. However, considerable overlap prohibits identifications based on these characters alone.
L. pallidus H. L. Clark, 1925, is raised to full species status and a key to the extant species and subspecies of Lytechinus is given.
