Hippocampus Bildarchiv (2)

Habitat: Dorsal spines (total): 1; Anal spines: 0. Gill slits not extending ventrally beyond pectoral-fin insertions; snout rounded, at most 65% of head length; post-orbital length at most 60% of snout length; maxillary barbels not fringed or very slightly fringed at base, shorter than head, unbranched and without tubercles or membranes (although a tiny rudiment may occasionally be discernible at their bases); outer mandibular barbels with few simple and rather long ramifications; branches of inner mandibular barbels short, subdivided and more or less tuberculate; mandibular teeth numbering 31-47 (40 in the neotype); dorsal-fin spine short and smooth anteriorly; denticulation of pectoral-fin spines finer on outer than on inner margin; humeral process narrow, triangular, rather pointed and not keeled ventrally; adipose fin rather long and distinctly separated from rayed dorsal fin, its height variable with specimens; head very broad, snout rounded and eyes small, in dorsal position. Colouration: Preserved specimens dark brown; according to Daget (1954), colour in life, olivaceous yellow on back and sides, lighter on belly. Body and adipose fin covered with large black spots, which become smaller on belly and on other fins. Reproduction: Oviparous. Distinct pairing during breeding. Aquarium Care: Would need a very large aquarium to house this Synodontis as befitting a large river species.
