Actinopteri (ray-finned fishes) > Siluriformes (Catfishes) > Mochokidae (Squeakers or upside-down catfishes) > Chiloglanidinae
Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335).

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

Africa: two areas, tributaries of the Pongolo and Komato-Incomati rivers in South Africa and Swaziland, and the Pungwe and middle and lower Zambezi in Zimbabwe. Threatened by water extraction, river regulation and sedimentation.

Maturity: L_m ? range ? - ? cm
Max length : 6.5 cm SL male/unsexed; (Ref. 7248)

Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal spines: 3; Anal soft rays: 8. Mouth is used as a sucking disc to hold its position in fast flowing waters. Gut length is less than standard length and the mandibular teeth are used to scrape invertebrates from stones.

Found in shallow rocky runs and riffles of clear rivers, at an altitude of 900-1200 m above sea level, and depths from 0.2 to 0.4 m (Ref. 52116). Feeds on invertebrates such as mayfly nymphs and caddis fly, blackfly or midge larvae grazed from rocks. Oviparous (Ref. 205). Breeds in summer (Ref. 7248). Distribution in southern Africa is restricted and may be threatened by alteration of its habitat (Ref. 52116).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous (Ref. 205). Distinct pairing during breeding (Ref. 205). Is likely to be an interstitial gravel spawner (Ref. 52116).

Estimates based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

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

Trophic level (Ref. 69278): 3.2 ±0.40 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 320).

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

Climate Vulnerability (Ref. 125649): (0 of 100) .

Price category (Ref. 80766): Unknown.
