Etymology: Mastacembelus: Greek, mastax, -agos = bite + Greek, emballo = to throw oneself (Ref. 45335);  polli: Named in honor of Prof. Dr. Poll, a famous Belgian ichthyologist who pioneered ichthyological studies on Lake Tanganyika (Ref. 56055).

Short description Morphology | Morphometrics

Dorsal spines (total): 22 - 29; Dorsal soft rays (total): 68-87; Anal spines: 2; Anal soft rays: 70 - 98; Vertebrae: 72 - 84. The species has protruding eyes, a small rostral appendage, a protruding lower jaw, a pointed caudal fin and a more elongated pectoral-fin shape (Ref. 56055). Posterior angle of lips is situated below the region from the middle from the eye up to a distance of about one-third of the diameter behind posterior border of eye (Ref. 56055). Upper corner of gill opening and dorsal edge of pectoral-fin base approximately at same level, clearly anterior to ventral edge of pectoral-fin base; dorsal edge of pectoral-fin base situated above upper corner of the gill opening (Ref. 56055). Lateral line continuous from posterior border of head up to one-third or half of distance between head and anus, discontinuous more posteriorly (Ref. 56055). Preanal length always shorter than postanal length; distance from anterior border of snout to last externally visible dorsal spine always longer than distance from anterior border of snout to last externally visible anal spine, and as a result origin of soft dorsal fin always posterior compared to origin of soft anal fin (Ref. 56055). Dorsal spines increasing in size from first to last (Ref. 56055). One well-developed, externally visible anal spine; a very small almost entirely reduced spine, hidden under the skin, can be present (Ref. 56055). Preopercular and preorbital spines are absent (Ref. 56055). It has a uniformly light brown overall background colour with numerous small, round, dark brown spots on the dorsal part of head, body and tail (Ref. 56055). Background colour lighter, more yellowish white on lips, ventral region of head, belly and most ventral part of tail (Ref. 56055). Pectoral fins whitish transparent without spots; dorsal, caudal and anal fins also whitish transparent (Ref. 56055).

Biology     Glossary (e.g. epibenthic)

Coastal in distribution; habitat is rocky bottom, flagstone, rock slides and pebbles (Ref. 56055).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00295 (0.00132 - 0.00659), b=2.93 (2.74 - 3.12), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (16 of 100) .
