LSIDs are persistent, location-independent,resource identifiers for uniquely naming biologically significant resources including species names, concepts, occurrences, genes or proteins, or data objects that encode information about them. To put it simply, LSIDs are a way to identify and locate pieces of biological information on the web.

Description

The unusual pear -like shape of the coffin ray distinguishes it from all other rays. Its body is flabby, with the two large, kidney -shaped electric organs visible on both sides of the head. The pectoral fins form a greatly enlarged disc about as wide as long, that is thick at the center and thin at the margins. ... source: Wikipedia

Species Lists

RLS profile v3
Abundance: 1
Commercial_Uses: None, other than trivial captures for aquarium trade
Common_Name: Coffin ray;Numbfish
Depth: 2–220 m
Description: The coffin ray has a distinctive double-lobed shape with very short tail. The species should be well known to most NSW and WAdivers because of the severe electric shock produced on contact. In many cases, divers receive shocks when placing a hand on apparently bare sand—the only sign of a concealed ray is its two fringed nostrils open at the sediment surface
Diet: The coffin ray feeds on comparatively large fish, which are stunned and pounced on, the lobes wrapping around and engulfing the victim
Distribution: Broome, WA, to Caloundra, Qld.
Frequency: 0.338
Habitat: Moderately exposed sand
IUCN_Threat_status: Not assessed
Invasive: Not known to be invasive
Max_size: 690 mm
Range: 211.125
Threats: No major threats to this species are known

Brief description: Shaped like two discs, one large and one small.
Description : Shaped like two discs; the head and pectoral fins form a large disc, while a second smaller disc is formed by the pelvic fins. Located on the second disc are two small dorsal fins, immediately followed by a similar-looking caudal fin. Body size up to 60 cm.
Biology : The Coffin Ray can deliver a powerful electric shock with an electric organ located in each pectoral fin. This organ is used to shock crabs, worms and fishes, which make up its diet. To swallow relatively large prey whole, it is able to greatly expand its mouth. When seen by divers it is usually buried in the sediment where a tell-tale rounded depression gives away its presence. The electric organs of the torpedo rays (family Torpedinidae) can deliver strong electric shocks (50 amps, with peak of pulses sometimes exceeding 1 kilowatt).
Habitat: Sand and mud bottoms in shallow bays and estuaries, but is also known to depths over 200 m.
Maximum size (cm): 60
Diet: Carnivore
Dangerous: It can deliver a strong electric shock when touched by scuba divers.
Colours: Grey, Brown, Black
Distribution: Eastern, southern and western Australia.
Habitat types: Marine
Depth: Shallow (1-30m),Deep (>30m)
Water column: On or near seafloor
Commercial species: False
