 Cat-eLog Data Sheet | |
|---|---|
| Scientific Name | Synodontis obesus Boulenger, 1898 |
| Common Name(s) | None |
| Type Locality | Opobo R., Old Calabar, Nigeria. |
| Synonym(s) | Synodontis loppei |
| Pronunciation | sin oh don tiss |
| Etymology | Synodontis: From the Greek syn, meaning together, and odontos, meaning tooth; in reference to the closely-spaced lower jaw teeth. This specific epithet literally means fat (obeseus,-a=fat). |
| Species Information | |
| Size | 320mm (12.6") SL. Find near, nearer or same sized spp. |
| Identification | All species in the genus Synodontis have a hardened head cap that has attached a process (humeral process) which is situated behind the gill opening and pointed towards the posterior. The dorsal fin and pectoral fins have a hardened first ray which is serrated. Caudal fin is always forked. There is one pair of maxillary barbels, sometimes having membranes and occasionally branched. The two pairs of mandibular barbels are often branched and can have nodes attached. The cone-shaped teeth in the upper jaw are short. S-shaped and movable in the lower jaw. These fish produce audible sounds when disturbed rubbing the base of the pectoral spine against the pectoral girdle. |
| General Remarks | There is some debate over the species name. ‘Obesus’ is a Latin adjective (meaning fat) that, according to nomenclatural rules, should be declined to agree with the gender of the genus. As Synodontis is feminine and obesus is masculine, the species name should be declined as obesa (feminine form of obesus). However, current scientific literature continues to treat the specific epithet as masculine, even though epithets for almost all other Synodontis species have been declined to their feminine forms. The cause of this is unknown. |
