As one of the smallest water pokemon in their habitat, Arrokuda are often assumed by outsiders to feed on plankton, for how else would a species barely more than half the size of a Magikarp feed? But it is no accident that Cramorant, their sole predator, has a long bill with which to pluck them from the water, for Arrokuda are swift, ferocious pack hunters capable in numbers of taking down even a Wailord.

Yet an Arrokuda's small size, aerodynamic shape, and powerful jaw leaves little room to fit in brainpower or eyesight. They track movement, not distinguishing the source of such, and often waste their energy pursuing anything from a blown-over tree trunk to a discarded pokeball, learning said item is inedible only once they bite down. Worse, humans have known from ancient times that a simple wave of a fishing net is enough to draw whole schools of these pokemon rushing inside, and their place on the food chain rendered them no less fit for human consumption.

There was a time when old, low-quality fishing rods around the world were even more likely to fish up Arrokuda than Magikarp or Basculin. However, this was not a function of Arrokuda's large numbers, but of a survival strategy that served this species well in the Pleistocene, yet proved a disaster in the Holocene. Only in Galar, a global leader in conservation, is the average trainer today likely to encounter an Arrokuda over the course of their pokemon journey. Thankfully, they have not been wholly extirpated elsewhere; apart from their presence in Safari Zones, Arrokuda populations survive on three continents in remote, highly protected rivers.
