Etymology: Mastacembelus: Greek, mastax, -agos = bite + Greek, emballo = to throw oneself (Ref. 45335); apectoralis: The species name, apectoralis, an adjective, alludes to the absence of pectoral fins, and is formed from the Latin 'a', meaning without, and 'pectoralis', a Latinized version of pectoral (Ref. 86808).

背棘 (总数) : 32 - 34; 背的软条 (总数) : 58 - 69; 臀棘: 3; 臀鳍软条: 66 - 67; 脊椎骨: 77 - 80. Diagnosis: Mastacembelus apectoralis differs from all other mastacembelid species by the absence of pectoral fins (Ref. 86808). It is endemic to Lake Tanganyika and is placed within the Lake Tanganyika species flock; it differs from other members of this radiation by a near absence of scales, present only on the margin of the caudal peduncle and between caudal-fin rays, a very short rostral appendage and well-developed adductor mandibulae muscles forming a distinctive head shape; the lack of pigmentation distinguishes this species from all other Tanganyikan species, with the exception of M. micropectus and M. cunningtoni, although the latter species has a distinctive dark spot on the caudal and pectoral fins; both M. apectoralis and its sister species, M. micropectus, lack teeth on the palatine; Mastacembelus apectoralis has 32-34 dorsal spines, and based on this count, is distinguished from five other species in the Lake Tanganyika flock, M. platysoma, M. zebratus, M. polli, M. cunningtoni and M. moorii, which have fewer spines, 21-29; however, all other Lake Tanganyika species have overlapping spine count ranges, 24-38, at least in part with that of M. apectoralis; vertebral counts of M. apectoralis, 77-80, are in the region of those of M. micropectus and M. albomaculatus, are greater than M. zebratus, but are lower than other Tanganyikan species (Ref. 86808).

Found in a complex rocky habitat, consisting of multiple layers of rock, at a depth of 3-7 m (Ref. 86808).
