Diagnosis: Body cylindrical and more elongate than in other Protopterus species (Ref. 81627). Pectoral and pelvic fins filamentous (Ref. 40587). About 85-95 scales on the longitudinal line between operculum and anus (Ref. 104724).

زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

Protopterus dolloi is not aestivating in cocoons during the dry-season, because the habitat in which it lives is never completely dry (Ref. 81627); although it never lost the capability to aestivate (Ref. 40587). Therefore, the tunnel which it digs is not for hibernation but functions as a protected chamber during reproduction, which takes place in the dry season (Ref. 81627). The male guards the eggs and larvae in the nest, which is built in the mud of the swamps, while the females can be found in the open water of the rivers (Ref. 41587, 81627). The food of Protopterus dolloi are fishes and insects, but during the time of reproduction its food is more vegetarian (Ref. 40587, 46852).

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6602   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00150 - 0.00963), b=3.10 (2.88 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.40 se; based on food items.
جهندگی (Ref. 120179):  خیلی آهسته, كمينه زمان لازم براي دو برابر شدن جمعيت بيش از 14 سال (Assuming tmax > 30).
