These guys can't see well - they seem to crash into everything as they swim along. But who needs to see when you have an electric jolt like they do? Shelly Beach
Coffin rays pack a 200V punch if you touch them - but this one doesn't seem to be able to see very well. Probably not an issue when you have other defenses
I discovered this fish when I received an electric shock. Fearing a major undersea cable had been exposed I waved the sand away to discover a weird, rubbery looking foot mat which turned out to be a Numbray!
