Open encyclopedia reference
The sharpnose guitarfish also known as the granulated guitarfish (Glaucostegus granulatus) is a species of ray in the Glaucostegidae family. They belong to the subclass Elasmobranchii which are cartilaginous fish that include sharks, rays, and skates as shown in their morphology. They have a flattened ray-like body and shark-like elongated snout. This species was first described by Georges Cuvier in 1829, and despite their appearance, they don't pose any threat to humans. As of April 2022, the IUCN has classified the sharpnose guitarfish as critically endangered.
