Larval development of the rock shrimp Rhynchocinetes typus Milne Edwards, 1937 (Decapoda, Caridea) reared in the laboratory

The first description of the larval stages of a representative of the family Rhynchocinetidae from the southeastern Pacific coast of South América is presented. Larvae of the rock shrimp Rhynchocinetes typus, from rocky subtidal environment of the Chile-Pera coast were reared in the laboratory at 22...
