Description: The eel family Congridae is now known to be represented in the western Indian Ocean (here regarded to be west of 60 E. from and including the Red Sea, to Cape Point) by 11 genera and 19 species as well as at least five distinct larval forms which have not yet been identified. More than half of these species inhabit the shallow and offshore waters of the tropical western Indian Ocean. The remainder are known only from cool-temperate waters off the Cape, with one deep-water Atlantic species and one Mediterranean species also present in this area. Considerable additions to this fauna can be expected as the deep waters off the east coast are more fully sampled. Congrina wallacei sp. nov., de- scribed here from 260-270 fathoms off southern Mozambique and Durban, has rather large teeth on the jaws, a long snout and about 168 vertebrae. At least one species spawns off the Cape, but the majority probably do so over the western edge of the oceanic basins north and south of Madagascar. The shallow-water species show strong affinities with the tropical and cool-temperate Indo-Pacific. , Rhodes University Libraries (Digitisation)

Fishes of the family Atherinidae of the Red Sea and the Western Indian Ocean with a new freshwater genus and species from Madagascar

Description: While some of the marine species enter estuaries, it is remarkable that no freshwater forms are known from East African lakes or from African rivers that flow eastwards. One species occurs in lakes in North Africa, and another in West Africa, and seven species of endemic Atherinid fishes have been found to be widespread in the freshwaters of Madagascar. A brief summary of the latter is given below, with a revised description of Teramulus waterloti (Pellegrin, 1932), and the new genus Teramulus, in which two species are shown to be present in Madagascar. , Rhodes University Libraries (Digitisation)

Fishes of the family Pentacerotidae

Description: Family Pentacerotidae - Formerly known as the Histiopteridae, Follett and Dempster 1963 have shed new light on the nomenclature of the categories in this family. The earliest genus is Pentaceros C & V, 1829. This has long been held in abeyance on the grounds that it was preoccupied by Pentaceros Schulze, 1760 as well as by Pentaceros Schroeter, 1782 (both for Starfishes). Follett and Dempster have however shown that neither Pentaceros Schulze nor Pentaceros Schroeter is valid, and that Pentaceros C & V is therefore not invalidated. Further, Pentaceros C & V, 1829 was used in primary zoological literature by Gilchrist in 1902, and by Thompson in 1916, and hence cannot be relegated as a nomen oblitum. The oldest available family category name is the PENTACERATINA of Gunther, 1859 (which was corrected by Gill, 1893 to PENTACERATOINA). Bleeker, 1861 used the family name Pentacerotoidei, and as these antedate the name Histiopteridae of Jordan 1905, the family name becomes PENTACEROTIDAE. , Rhodes University Libraries (Digitisation)

The clingfishes of the Western Indian Ocean and the Red Sea

Authors: Smith, J.L.B. (James Leonard Brierley), 1897-1968
Date: 1964
Language: English
Type: Text
Identifier: vital:15017 , http://hdl.handle.net/10962/d1019796 , Ichthyological Bulletin; No. 30
Description: In only few cases is anything definite known about the reproduction of Clingfishes. Probably all produce eggs, in some cases (see Eckloniaichthys below) this somewhat abnormally follows internal fertilization by copulation. In those cases that have been studied the eggs are laid in a single layer and are strongly adhesive to the surface of the rock, weed or shell on which they are deposited. The number of eggs varies from about a dozen to many hundreds. The female of the large South African Chorisochismus dentex has been observed to guard the eggs and to assist aeration by fanning. In some species there is marked sexual dimorphism in body shape and in dentition, while males may have a large genital papilla. , Rhodes University Libraries (Digitisation)
