Etymology: Erpetoichthys: Greek, erpeton = creeping thing + Greek, ichthys = fish (Ref. 45335);  calabaricus: Named after the locality where the fish was taken: Old Calabar (Ref. 42916).

پراكنش كشورها | مناطق سازمان خوار و بار جهاني (FAO) | Ecosystems | ظهور | Point map | معرفي | Faunafri

Africa: coastal species, inhabiting river estuaries from Ouémé River in Benin to Sanaga River in Cameroon (Ref. 53784, 81628). Also reported from the Chiloango River (Ref. 1878, 2835, 3188, 42870, 43033, 81263), but this record needs confirmation and needs to be supported by additional material evidence (Ref. 53784, 81628).

توصيف مختصر ريخت شناسي | ريخت ستجي بوسيله انداره گيري

خارهاي باله پشتي (کل): 7 - 13; شعاع نرم باله پشتي (کل): 0; خارهاي باله مخرجي 0; شعاع نرم باله مخرجي: 9 - 14; مهره ها: 110 - 113. Diagnosis: The dorsal fin is composed of a series of well-separated spines each supporting one or several articulated rays and a membrane (Ref. 42791). Erpetoichthys calabaricus is distinguished from all Polypterus species by its very elongated, anguilliform body and the absence of ventral fin and subopercle (Ref. 2835, 42768, 81263).

زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

Facultative air-breathing (Ref. 126274); Found in slow flowing rivers and standing waters (Ref. 557). Apparently restricted to reedy habitats (Ref. 42768). It moves snake-wise over the bottom, but it can also side-wind quite rapidly through the water (Ref. 42873). Feeds at night on worms, crustaceans and insects (Ref. 7020). Able to breathe air and thus can tolerate low oxygen concentrations. Larvae have external gills and resemble salamander larvae (Ref. 557). The maximum size of 90 cm TL (Ref. 3188) is probably erroneous; the largest size in collections is 37 cm (Ref. 78138).

Life cycle and mating behavior بلوغ | تولید مثل | تخم ریزی | تخم ها | Fecundity | توزاد ( لارو)

Parallel swimming courtship; female deposits few eggs between anal fins of male, where they are fertilized and then scattered in vegetation where they immediately stick to substrate. This procedure is repeated many times. Eggs are 2.1-2.6 mm in diameter. Larvae hatch after 70 hours but remain attached to vegetation; 22 days after hatching the yolk sac is absorbed and larvae start feeding.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00166 (0.00112 - 0.00246), b=3.02 (2.91 - 3.13), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.40 se; based on food items.
Generation time: 1.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
جهندگی (Ref. 120179):  پايين ، كم, كمينه زمان لازم براي دو برابر شدن جمعيت 5/4 – 14 سال (tmax=20; Fec = 264).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
