Abstract
Two individuals of the palaemonid shrimp Phyllognathia cerathophthalma (Balss, 1913) were observed feeding on brittle stars (Ophiuroidea) in Bali, Indonesia. One of the shrimps was observed capturing, subduing, and devouring Ophiactis savignyi (Müller & Troschel, 1842) (Ophiactidae), whereas the other was observed feeding on a detached arm of Ophiothrix sp. (Ophiotrichidae). Therefore, P. ceratophthalma joins a small ecological guild of shrimps, which are also phylogenetically related, specialized in the predation of echinoderms, together with its congener P. simplex Fujino, 1973 and the harlequin shrimp Hymenocera picta Dana, 1852.
Résumé
Deux individus de la crevette Phyllognathia cerathophthalma (Balss, 1913) appartenant à la famille Palaemonidae ont été observés en train de se nourrir des ophiures (Ophiuroidea) à Bali, Indonésie. L’une des crevettes a été observée au moment de capturer, maîtriser et dévorer Ophiactis savignyi (Müller & Troschel, 1842) (Ophiactidae), tandis que l’autre a été vue s’alimentant d’un bras détaché d’Ophiothrix sp. (Ophiotrichidae). Par conséquence, P. ceratophthalma joint une guilde écologique des crevettes, phylogénétiquement proches, qui sont spécialisées en prédation des échinodermes, qui inclut aussi l’autre espèce du même genre, P. simplex Fujino, 1973, ainsi que la crevette-harlequin Hymenocera picta Dana, 1852.
