|Scientific Name||Synodontis contractus Vinciguerra, 1928|
|Common Names||Bug Eyed Squeaker
Big-nosed Upside Down Catfish, Bugeye Squeaker, Davids Rückenschwimmender Congowels (Germany), Lille Rygsvømmermalle (Denmark)
|Type Locality||Rubi River at Buta, Democratic Republic of Congo.|
|Pronunciation||sin oh don tiss - kon TRACK tah|
|Etymology||According to Cuvier, Synodontis is an "ancient name for an undetermined fish from the Nile". It is apparently not derived, as often reported, from syn-, together and odous, tooth, presumed etymology of the lizardfish genus Synodus and in reference to the closely-spaced lower jaw teeth of both genera.|
- CotM 2005 February
|Size||60mm or 2.4" 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.
It is very similar in colour pattern to the more commonly encountered Synodontis nigriventris. The main differences being that S. contracta has a bigger head, broader mouth and far larger eye.
|Sexing||Unknown, hard to tell differences in genital papillae in such a small species.|
