deskripsi pendek Morfologi | Morfometrik

Duri punggung (Keseluruhan (total)): 16 - 17; duri punggung lunak (Keseluruhan (total)): 9-10; Duri dubur 3-4; Sirip dubur lunak: 8 - 9. A small to medium-sized cave-dwelling haplochromine with relatively deep body depth with greatest body depth at base of seventh or eighth dorsal spine (Ref. 82798). Otopharynx antron has a larger eye, 31.4-34.7% of head length, than most other Otopharynx species. It has fewer lateral-line scales (29-31) than Otopharynx argyrosoma and a larger lower-jaw length than Otopharynx heterodon (Ref. 82798). It is distinguished from Otopharynx spelaeotes and Otopharynx lithobates by its primarily unicuspid teeth in the outer rows of the oral jaws, by its smaller horizontal eye diameter, by a deeper caudal peduncle, and additionally from O. spelaeotes by having fewer teeth in the outer row of the left lower jaw (15-19) (Ref. 82798).

Cave-dwelling; males have been observed defending small caves with sandy bottom mostly against conspecific males (Ref. 82798). Unicuspid teeth suggest diet of larger invertebrates or even fish (Ref. 82798).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
