Actinopterygii (ray-finned fishes) > Siluriformes (Catfish) > Mochokidae (Squeakers or upside-down catfishes)
Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335);  orthodontus: A combination of the Greek word orthos, meaning straight or erect, and the Greek word odontos, meaning tooth; this name refers to the mandibular dentition in this species, which is relatively straight and evenly spread across the dentary as compared to most other members of the genus (Ref. 87986).

Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 5; Anal spines: 0; Anal soft rays: 9 - 10; Vertebrae: 32 - 34. Chiloglanis orthodontus is a relatively small species (<30mm SL) that can be distinguished from all other Malagarasi congeners by possessing dentary teeth spread out across the mouth opening as opposed to being concentrated at the midline, and a very short dorsal spine (4.1–7.8% SL vs. always greater than 8.2%) (Ref. 87986). This species is further distinguished from all Lake Tanganyika region species except C. productus, by a relatively long adipose fin (25.0–31.3% SL vs. <23.4% SL in all other Chiloglanis species except C. productus (22.5– 26.2% SL)) (Ref. 87986). Additional features useful for distinguishing this species from other species of Chiloglanis include a relatively small oral disc (width: 16.5-21.7% SL; length: 12.1-16.3% SL) with relatively elongate barbels (maxillary: 9.4-14.8% SL; lateral mandibular: 3.8-10.7% SL; medial mandibular: 3.8-5.9% SL) (Ref. 87986).

Biology     Glossary (e.g. epibenthic)

Rheophilic species; lips form ventrally-directed oral disc for adhering to and feeding upon objects in fast flowing waters; most commonly encountered in small riffles, or in peripheral regions of rapids where the water velocity is much slower (Ref. 87986).

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [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):  3.1   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
