Common shovelnose ray
species of fish
The common shovelnose ray, giant shovelnose ray or giant guitarfish (Glaucostegus typus) is a species of 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), including mangrove, estuaries and reportedly also in freshwaters. 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.
The public source identifies “Common shovelnose ray” as species of fish. This brief keeps that definition visible, then builds a research path around Common, shovelnose and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Common shovelnose ray”, the useful work is to connect “species of fish” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 4, 2026. The linked authority identifier is Q3316458. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
