Short description Morphology | Morphometrics

Dorsal spines (total): 23 - 24; Dorsal soft rays (total): 4-5; Anal spines: 3; Anal soft rays: 6 - 7. Diagnosis: Eretmodus cyanostictus is characterized by a terminal mouth and a number of bright blue spots on the head and upper half of the body (Ref. 92306). About 5 light bars are present on the side of the body but evident only on the lower half of the body and none crossing the posterior en of the body or caudal peduncle (Ref. 92306).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: endemic to Lake Tanganyika, occurs in the southern part of the Lake, from Kipili (Tanzania) to Moliro (Democratic Republic of the Congo) (Ref. 46829).

Biology     Glossary (e.g. epibenthic)

Occurs in rocky areas (Ref. 53528). Adults occur in the turbulent, highly oxygenated shallow waters of the surf zone; found in the shallows of a gradually sloping rocky coast where some sand is found between the rocks; solitary and to some extent, territorial; heavy body and small swim bladder result in negative buoyancy (Ref. 6770). Feeds on algae which are scraped from the rocks (Ref. 6770, 46829). Both parents brood their young in the mouth (Ref. 52921, 86760).

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01738 (0.00863 - 0.03498), b=2.96 (2.79 - 3.13), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.1   ±0.1 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (tm<1).
Vulnerability (Ref. 59153):  Low vulnerability (11 of 100) .
