Remark |
: |
Distribution: Indo-Pacific and Atlantic Ocean (1-2 spp). Primarily marine with one Rhina in freshwater. Mostly found in warm temperate to tropical inshore continental seas and rarely deeper than 400 m. Habitat: Strong swimmers and bottom-dwellers that rest rather than burrow on muddy or sandy bottoms. Diet: Feed on benthic invertebrates amd small bottom-dwelling fishes. Use: Sought after for their meat and highly valued large fins that has led to overfishing and population decline in some areas. Popular in public aquaria. Caught mainly as bycatch by trawls, gill and tangle nets and longlines. Morphology: Wedgefishes are shark-like rays, the size of which is medium to large (0.7-3.1 m TL as adults and weigh at least 227 kg). It has a variably depressed trunk, weakly formed disc, a head either thickened and broadly domed, orflattened wedge-shaped or rounded; pectoral fins are triangular and joined with the body behind eye level; long and narrow nostrils, usually lie oblique to a small horizontal mouth with rounded oval teeth that lack distinct cusps; anterior nasal flaps poorly developed and do not form a nasal curtain; spiracles large with 0-3 skin folds along the hind margin; robust tail slightly longer than the disc; upright dorsal fins 2, first above the pelvic fins; a well-developed bilobed caudal fin with strongly concave posterior margin; pelvic fins moderately sized, angular and not divided inlto 2 lobes; skin with minute denticles and there is a variably developed series of thorns alon ghte dorsal mid-line, and usually 2-3 short serires on each shoulder; dorsal surface mainly yellowish to greyish brown and white ventrally; often with rows of white spots and ocelli, and often with a black blotch on each pectoral fin (pectoral marking) that is variably surrounded by white spots (generally obvious in young); undersurface of the snout can have a blackish marking. Genera: Rhina, Rhynchobatus, Rhynchorhina. |

Important recommendation:
The list below must not be used as an authority reference synonymy list like those found in scientific published revisions, which must be the source to be used and cited eventually when they exist.
Rather, it reflects the current content of FishBase, and the progress with respect to synchronization with the Catalog of Fishes. However, we think it can be useful for users to assess the quality of information in FishBase, to start new work on the family, or to cross-check with other lists.
But we appreciate to be cited in publications when this list has been of any working value. In particular, for published scientific, we suggest then to cite it in the Material and Method section as a useful tool to conduct the research, but again, not as a taxonomic or nomenclatural authority reference.
Unless it is explicitly precised, the list is not complete, please search all original names published for the family in the Catalog of Fishes (genera, species), including those with uncertain or unknown status, that are not included in FishBase when they are not attached to a valid species.
This list uses some data from Catalog of Fishes (not shown but used to sort names).
In the column CofF, the digit indicates the status of synchronization with CofF: 0: Not checked; 1: Same status; 2: Different status; 3: Other combination; 4: Synonym in CofF; 5: Species/Subspecies issue; 6: Synonym of another species in CofF; 7: Not in CofF; 8: Should not be in CofF. The CofF version currently used is the one published on 23-07-2014 (Ref. 97102).
The list ordered as follows:
