description Coffin Ray Overview
The coffin ray is a species of electric ray in the family Hypnidae, endemic to the coastal waters of southern Australia. As a benthic ambush predator, it buries itself in sand or mud during the day and becomes active at night. It is notable for its ability to generate a powerful electric shock despite its relatively small size. This discharge is used both to subdue prey and as a defense mechanism against potential predators.
help Coffin Ray FAQ
How strong is the coffin ray's electric shock?
The coffin ray can deliver a powerful defensive shock from specialized electric organs beside its head. The discharge helps deter predators and may assist in subduing prey, so a live animal should not be handled.
Why is Hypnos monopterygius called a coffin ray?
Its soft, pear-shaped body and short tail create a distinctive outline that inspired the common name. The same Australian species is also widely called the numbfish.
Where does the coffin ray live?
Hypnos monopterygius is endemic to Australian coastal waters and lives on or near the seafloor. It commonly rests partly buried in sand or mud and becomes more active when hunting.
What does a coffin ray eat?
It ambushes fishes and bottom-dwelling animals, sometimes swallowing prey surprisingly large relative to its body. Its expandable mouth and electric discharge support this unusual feeding strategy.
