Porcupine/Thorny Stingray

Urogymnus asperrimus


Pale gray to dark brown with numerous thorns on surface; scattering of white spots; ovate disc with humped central portion, tail about equal to disc length. Solitary, often partially buried in sand. Saw this one partially buried in sandy bottom, quite large, easily 1.5 meter wide, was not able to get better picture to show the thorns on its back.


New Organism to Project Noah. They are considered rare among Stingray species and we were fortunate to see 2 of them during my recent trip to Maldives.
