Appearance
It reaches up to 2.7 m (8.9 ft) in length, and is greyish-brown to yellowish-brown above with a paler snout. This species has been tested for colour vision using choice experiments that control for brightness. It was the first rigorous behavioural evidence for colour vision in any elasmobranch.
Range and habitat
The common shovelnose ray, giant shovelnose ray or giant guitarfish is a fish in the Rhinobatidae family found in the central Indo-Pacific, ranging from India to the East China Sea, Solomon Islands and northern Australia. It is found in shallow coastal areas to a depth of at least 100 m (330 ft), among them mangrove, estuaries and reportedly also in freshwaters.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Sharks and rays grow slowly and have few young. A fishery that treats them as bycatch can empty a coastal form.
In crisis
CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
