The cowtail stingray is a large ray that lives in warm coastal seas and sometimes swims up rivers. Its most noticeable feature is a wide, flag-like fold of skin on its tail. It has a venomous spine on its tail, so it should be left alone.1

The serrated spine is potentially dangerous, and the cowtail stingray is regarded as particularly dangerous to handle.1

Ikora iki iyo ifite ubwoba?

When threatened, it flees at a 45° angle away from the predator, keeping the predator in view while covering distance.1

Ibintu by'ukuri

A cowtail stingray was recorded in the Ganges River about 2,200 km (1,400 mi) from the sea.1

Resting groups of cowtail stingrays often form a rosette, with their tails pointing outward so they can see threats from every direction.1

Its large, regularly arranged skin bumps have made it a source of shagreen leather since ancient times.1

The cowtail stingray and reticulate whiprays often form mixed-species groups, probably because the whiprays detect predators well thanks to their long tails.1

Its tail fold and tail tip are black, and the tail carries sensors that act as a secondary warning system.1

Newborn cowtail stingrays have completely smooth skin, and their denticles develop quickly after birth.1
