Presumed Chemosensory Hairs in Talitrid Amphipods (Crustacea)

Presumed Chemosensory Hairs in Talitrid Amphipods (Crustacea) Ent. scand. 4. 1973. 171-180. Introduction Recently the structure of sensory hairs from the antennulae and antennae of the Talitrid amphipods Orchestia platensis Krøyer and Talorchestia deshayesii Audouin was described on the basis of scanning and transmission electron microscope observations and it was concluded that their morphology strongly sug- gests a chemosensory function (Dahl, in press). In the course of these investigations it was ob- served that sensory hairs of a similar shape occurred in great numbers also on other parts of the body of the Amphipods in question. The occurrence of such presumed chemosen- sory organs on various appendages may be of considerable interest in connection with ques- tions concerning ecology and behaviour. The aims of the present paper therefore is to describe the distribution and external morphol- ogy of such organs on different parts of the body in a number of talitrid Amphipods.
