Abstract
Abstract During exploratory trips conducted between August and December 2016, six shrimps, found in association with the crinoid Nemaster grandis A.H. Clark, 1909, ere collected in Chichiriviche de la Costa, Vargas State (Venezuela). A photographic record of the crinoids and the shrimps was conducted in situ. Shrimps were preserved in ethyl alcohol 90% and carried to the Laboratorio de Carcinologia de la Universidad de Oriente, Nucleo Nueva Esparta. Once in the laboratory, the shrimps were taxonomically described and sexed. Shrimps were identified as Periclimenes crinoidalis Chace, 1969, constituting the first record of this species in Venezuelan waters. These findings also expand the known distribution range for the crinoid N. grandis in Venezuela, where the species exhibits two morphotypes, one of them not previously described. Additionally, a table with the species of decapods found associated with echinoderms in Venezuela is provided.
Highlights
Many crustaceans are often found in association with members of their own, or of another phyla more often than perhaps any other major group of marine invertebrates (Ross, 1983)
Associations between shrimps and echinoderms have been studied by Chace (1969), Críales (1984), Bruce (1986), and Berggren and Svane (1989), among others
More than 20 species of the genus have been reported in the Caribbean Sea, some of them in association with sponges, anemones or echinoderms (Chace, 1956; Chace, 1972; Críales, 1984; De Grave and Anker, 2009)
Summary
Many crustaceans are often found in association with members of their own, or of another phyla more often than perhaps any other major group of marine invertebrates (Ross, 1983). Associations between shrimps and echinoderms have been studied by Chace (1969), Críales (1984), Bruce (1986), and Berggren and Svane (1989), among others. Little is known about associations between species of the genus Periclimenes and crinoids in the Caribbean.
