Goal for the week 17.5 hours
The coffin ray or numbray (Hypnos monopteygius) is an electric ray off the coast of Australia. The coffin ray feeds by hitting prey with an intense 200v electrical shock, its shock has also been known to make divers convulse excitingly, but is generally not fatal. It is called a coffin ray because when dried it looks like a coffin. They also have a symbiotic relationship with a black worm-like eye parasite. The worm attaches itself to the rays eye and then when the ray is buried in the sand it wiggles wildly attracting prey to the ray.
