Etymology: Hemitaeniochromis: Greek, hemi = half + Latin, taenia, -ae = strip + Greek, chromis = a fish, perhaps a perch (Ref. 45335);  brachyrhynchus: Named in reference to the abbreviated preocular region of the head; brachyrhynchus is a noun in apposition (Ref. 91204).

Short description Morphology | Morphometrics

Dorsal spines (total): 17; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 9. Hemitaeniochromis brachyrhynchus is readily distinguished from its formal congener H. urotaenia, by its narrow lacrimal bone whose width, at the midpoint of the bone, is one-third of the orbit length (vs. nearly equal to the orbit length in H. urotaenia); by its snout being shorter than the orbit length (vs. longer in H. urotaenia); by its much larger eyes, the orbit length being about 36-38% of head length (vs. 22-28% in H. urotaenia); by its shorter lower jaw which is about 39-41% of head length (vs. 45-51% in H. urotaenia); and by its melanin pattern, which is composed of spots and line segments that are less well-defined than those of H. urotaenia (Ref. 91204).

Biology     Glossary (e.g. epibenthic)

Widely distributed but rare; apparently around rocks in rather deep water; possibly paedophagous diet (feeding on eggs and larvae) (Ref. 91204).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [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):  3.8   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  High to very high vulnerability (73 of 100) .
