The larval and post-larval stages of Gymnammodytes semisquamatus (Jourdain)

Abstract

In the course of investigations (1955–8) into the Ammodytidae of the south of the Isle of Man, five species of sand eel were identified: Gymnammodytes semisquamatus (Jourdain, 1879), the Smooth Sand Eel; Ammodytes lanceolatus Lesauvage, 1825, the Greater Sand Eel; A. immaculatus Corbin, 1950; A. tobianus Linnaeus, 1758 ( = A. lancea Cuvier), the Lesser Sand Eel; A. marinus Raitt, 1934.Five different types of post-larvae were obtained and investigated. Four of these were the post-larvae of the above four Ammodytes species and the fifth type proved to be Gymnammodytes semisquamatus.
