Maturité: Lm ?  range ? - ? cm
Max length : 35.2 cm SL mâle / non sexé; (Ref. 2801)
Rayons mous dorsaux (Total) : 9 - 10; Vertèbres: 34 - 36. Lips with transverse plicae on inner surface; snout very prominent, ending in a big fleshy upwards turned transverse appendix; eyes extremely small, generally in dorsal position. Can be distinguished from L. nasus by its smaller eyes and higher vertebral and scale counts (Ref. 12456).
Known only from the rapids of the Congo River where it appears most adapted. Among its adaptations are the reduce diameter of the eyes; the dorso-laterally flattened shape of the head, the very large lips which are apparently adapted for suction; the latero-ventral arrangement and form of the paired fins which is largely extended and compressed ; and the blue or bluish coloration (Ref. 26192).
