(Catfish) > Clariidae
Etymology: Clarias: Greek, chlaros = lively, in reference to the ability of the fish to live for a long time out of water; insolitus: Specific name from the Latin insolitus, meaning strange; in reference to the combination of hypertrophied sensory canal pores and a knife-shaped anterior fontanel, which is not seen in other Southeast Asian Clarias.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Tropical
