Xingu river ray

Potamotrygon leopoldi

Xingu river ray

Xingu river rays have a venomous sting on the top of their tail.
Because of their ability to camouflage on the ground of the river, they are feared by the natives who often use a stick to sting the bottom of the water before venturing there.

Xingu river rays reproduce by penetration : males have 2 hemipenis at the base of the tail.
They are ovoviviparous : the eggs are formed, incubate and hatch inside the female, the young are born completely formed.
