Etymology: Pellonula: Latin, pellis = skin + Latin, nullus = no one (Ref. 45335). More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; pelagic-neritic; anadromous (Ref. 51243). Tropical; 13°N - 13°S
Africa: coastal rivers from Liberia to Angola, but absent in the area between Ghana and Niger River delta (Ref. 2244, 2849, 28136), except for Lake Nokoué (Ref. 81269). The type locality of the syntypes of Pellonula stanleyana, 'Stanley Falls' (Ref. 1878, 2263) seems to be a locality error and should be 'Cette Cama [= Sette Cama]' in Gabon (Ref. 188, 2244). Except for its occurrence in the Léfini River (middle Congo River basin) (Ref. 88782), this species was not observed far upstream rivers (Ref. 2244).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm SL male/unsexed; (Ref. 188)
soft rays: 16 - 21. Diagnosis: Pellonula vorax is characterised by having the first prepelvic scute better developed and longer than the following ones, and located in front of the pectoral-fin bases; also characteristic are the outward-curving premaxillary teeth (Ref. 2244, 2849, 81269, 81631). It resembles Pellonula leonensis, which has small and inward-curving teeth and no pre-pectoral scutes (Ref. 188). Absence of large canine teeth in the upper jaw distinguishes it from the genera Cynothrissa and Odaxothrissa (Ref. 188, 81631).
Occur in rivers and streams. Form large schools in the lower reaches (Ref. 2244).
