Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Body shape (shape guide): short and / or deep; Cross section: flattened.
Adults occur in the rapids but is also captured in deep zones of main rivers with the use of fish bait. They are essentially carnivores feeding on small fish, crabs, mammals, lizards and coleopteran insects. Their opportunistic behavior allow them to adapt to various biotopes (Ref. 12225). They are timid and not aggressive but possess powerful dentition that can cause serious bites, and is therefore, potentially dangerous. Import is prohibited in some areas. However, the incorporation of this species in fish-based house security systems has been proposed (see Ref. 9506).
