Summary
Abstract: Electroretinograms and intracellular recordings were conducted on the giant Antarctic isopod Glyptonotus as well as the common amphipod Orchomene plebs. Eye material from starfish, marine mites, isopods and amphipods, and dragonfish were analysed by gas chromatography to confirm the distribution of fatty acids in the eyes of surface and bottom creatures. Observations were made on peculiar minute hairs which cover the entire body of Glyptonotus and are only visible under high magnification. Ectoparasitic copepods and a blind and possibly primitive crustacean were collected from the underside of Antarctic starfish.

LABORATORY Ancillary Description
Quality Most of the specimens were fixed, cut, examined under the light and/or transmission electron microscope and therefore no longer available. A few collected specimens are with the investigator at Jacobs University. In addition, lots of photographs (electron micrographs of eyes and other tissues of Antarctic fishes and crustaceans) are in his collection and a few until now uncut blocs of embedded tissue samples are also still available.
