Comparative morphology and cytology of the olfactory organs in Moray eels with remarks on their foraging behavior

The Anatomical Record

Abstract

This study compares the morphology and cytology of olfactory organs in moray eels (Muraenidae), particularly Siderea grisea and some species of the genera Echidna, Gymnothorax, and Lycodontis, fishes that are top predators in shallow-water marine habitats. Some of the species search visually for food while others search by olfaction. The morays were collected in the Red Sea; the nasal olfactory organs were dissected and fixed in Bouin's solution for light-microscopy, and 3.5% glutaraldehyde for electron-microscopy studies. In each studied species the olfactory rosettes are elongated structures situated in closed olfactory chambers between anterior tubular inlet nares and slit-form posterior outlet openings. The double row of lamellae constituting these rosettes are round in Siderea and Echidna and elongated in the other species. They are attached at their base to a median raphe and range in number from 20 in the youngest observed Siderea to 168 in Gymnothorax of 1,500 mm total length. As in other teleosts, the lamellae are covered by a ciliated epithelium composed of three types of sensory cells: two of these, ciliated sensory neurons and ciliated supporting cells, differ in detail, length, and thickness of their cilia and intr...Continue Reading
