Popis:	Living, freshly collected individuals of three species of snapping shrimps were studied to determine any differing morphological, developmental, and ecological features: Alpheus heterochaelis, collected from Beaufort, NC; A. angulosus, found mainly in Jacksonville, FL, but also at one site in Beaufort; and A. estuariensis, collected at another Jacksonville site. Structural characteristics of these superficially similar species are summarized, with particular attention to coloration. Adult A. angulosus individuals have blue-green 2nd antennal flagella (vs. tan in the other two species) that are significantly shorter than those of A. heterochaelis. Alpheus angulosus and A. estuariensis bear smaller eggs ( 1 mm), and the former species displays the zoea larval form typical of alpheids (vs. abbreviated larval development in A. heterochaelis).
