Blue Catfish
Neoarius graeffei
Neoarius graeffei, or blue salmon catfish, is a species of catfish found in freshwater rivers of Australia and Papua New Guinea. This species is most identifiable by its large, shark-like dorsal fin that is led by a poisonous spine. Like other catfish, the blue salmon catfish is known to use electrical pulses to sense prey in the water. This prey sensing mechanism may be the reason that these catfish are known to eat the land dwelling hopping mouse at a high rate.

What it does
Their diets include arthropods, insects, aquatic plants, mollusks, prawns, crayfish, fishes and bottom detritus. Recent studies have found large sections of the population are eating hopping mice, but it is not known if these mice are consumed after drowning or picked out of the air. These food sources are found using an internal system that resembles electrical sonar.
