- Description: Family Gaterinidae - Fairly robust usually deeply ovoid body, moderately compressed, covered with moderate to small strong adherent ctenoid scales, mostly only front of muzzle naked. Vertical fins partly scaly. Lateral line complete, concurrent with dorsal profile, but in adults not very distinct, tubules oblique, fewer than series of scales. Snout not pointed, moderately to markedly blunt. Mouth moderate, little protractile, maxilla slips below preorbital for most of its length. Lips well developed, often greatly swollen with age. Feeble cardiform teeth in bands in each jaw, outer series often enlarged, no teeth on palate or tongue. Chin with distinct pores, no central groove behind symphysis. Preopercle coarsely serrate in young, finer w ith age, obsolescent in very large fishes. Gill membranes free from isthmus. Gillrakers well developed, stout, spiny behind, 20-40 on whole outer arch. Dorsal continuous, of (9)10-14 spines and 15-26 rays, total 27-35, spines well developed, moderate to powerful, fewer than soft rays, but spinous part mostly with longer base, fin of almost uniform height to deeply notched, usually less so with age. Anal short, height exceeds base, III (6)7-8(9), 2nd spine mostly longer and stouter than 3rd. Caudal rounded in juveniles, feebly emarginate or truncate with age. Pectoral distinctly shorter than head. Juveniles up to about 40mm differ from the adults in certain features. They show some Pomadasyid characters i.a. the lateral line is continuous, the tubular scales adjacent; no pores are visible on the chin and the maxilla reaches to below the eye. Also the predorsal scaling ends in mid interorbital, and the scale rows above the lateral line are fewer. With growth the scale rows increase in number, but not the tubular L .l. scales, which become separated, the predorsal scales extend to the nostrils, while the snout extends, the maxilla not reaching to eye. , Rhodes University Libraries (Digitisation)

Sand-dwelling eels of the Western Indian Ocean and the Red Sea

- Description: The Western Indian Ocean has been found to be notably rich in marine eels. The Moray eels have been treated earlier (Bulletin No 23). In the present revision are described eels of the families OPHICHTHIDAE, ECHELIDAE, M ORING UIDAE, and NEENCHELIDAE, which are chiefly sand-dwelling forms, norm ally not free swimming by day. Some favour muddy areas where the water is turbid, and are found in estuaries, sometimes in or near fresh water. None of these eels are of any economic importance in the Western Indian Ocean though some are eaten by the natives in parts of the region. Only few attain any size, the majority are small and seldom encountered by the ordinary fisherman, in many cases they have been unknown to the local inhabitants. Our specimens were obtained chiefly by rotenone poisoning of suitable areas, mainly intertidal. , Rhodes University Libraries (Digitisation)
