Summary:
A very large stingray with the disc more than 1.4 times wider than long and covered in many large dermal denticles with star-shaped bases, especially on the snout.

The Smalleye Stingray is semipelagic and has been filmed flapping it's very wide pectoral fins up and down like butterfly and manta rays. Video of a Smalleye Stingray filmed off the coast of Mozambique.
