  • It is found in the upper Congo Basin, (Particularly Luvilombo Falls on the Luvilombo River)
  • Habitat: It is a benthopelagic; freshwater species.
  • Size: These fish are tiny 37–48 mm-long that can grow up to a size of around 96 mm.
  • It scales the Luvilombo Falls in the upper Congo Basin.
  • Shellear’s climbing abilities are made possible by tiny, hook-like projections on specialized pads on their pectoral and pelvic fins, along with hypertrophied muscles that enable them to carry their weight.
  • Why do they do it?
    • The researchers said the fish may climb upstream to find suitable living conditions and areas of the waterway with less competition and fewer predators.
  • The researchers identified two major human threats to the species:
    • Illegal fishing using fine-mesh mosquito nets that can easily catch the fish,
    • Water extraction for irrigation which has in some years depleted the Luvilombo River
