- Coffin_ray abstract "The coffin ray (Hypnos monopterygius) is a species of electric ray endemic to Australia, where it is common in inshore waters shallower than 80 m (260 ft). It is the sole member of its genus and of the subfamily Hypninae in the family Torpedinidae, which some taxonomists prefer to elevate to the full family rank as Hypnidae. This small species typically reaches 40 cm (16 in) in length. Greatly enlarged pectoral fins and an extremely short tail, coupled with diminutive dorsal and caudal fins all concentrated towards the rear, give the coffin ray a distinctive pear-like shape. It is a varying shade of brown in color above, and has tiny eyes and a large, highly distensible mouth.The sluggish and nocturnal coffin ray frequents sandy or muddy habitats, where it can bury itself during daytime. It can produce a powerful electric shock reaching 200 volts for attack and defense. This species is a voracious predator that feeds mainly on benthic bony fishes, often tackling fish approaching or exceeding itself in size. On occasion, it may also consume invertebrates and even small penguins and rats. Reproduction is aplacental viviparous, in which the developing embryos are nourished by yolk and maternally produced histotroph ("uterine milk"). The female gives birth to 4–8 pups during summer. The coffin ray can deliver a severe, albeit non-fatal, shock to a human. Not valued commercially, it is very hardy and can usually survive being captured and discarded. The International Union for Conservation of Nature (IUCN) has listed this species under Least Concern, as its population does not seem threatened by human activity.".
