The giant guitarfish (Rhynchobatus djiddensis) is also called the whitespotted wedgefish. The giant guitarfish is a large fish species of the family Rhinidae and genus Rhynchobatus.
Rhynchobatus has two Greek elements, rhingcos meaning 'snout' and -idos meaning 'a string ray.' They have a gray or brown colored body with a variety of patterns. There are four closely related species of giant guitarfish.
This species complex includes white-spotted guitarfish, broad nose wedgefish, and smooth nose wedgefish, also including the giant guitarfish. These are called shark-like rays. These fishes with other families of rays are at risk of extinction.
These fish species have slow maturity and growth. They have characteristic gill slit and mouth, which resemble a ray.
While fishing they are caught by demersal tangle net and sometimes by longline fisheries and trawl, impacting their populations. They are also used as game fish and their fins and flesh are sold.
They do well in a public aquarium. Further research and studies need to be done to learn more about their population, range, habitat, and taxonomy. In the meantime, read on for all there is to know about this intriguing species.
