Umbtail moves silently through the darkness, waiting for days for prey to arrive. When it snatches its victims with its incredibly strong coils, it dazzles them with the golden rings on its body to stun them and make it harder for them to escape.

To withstand the crushing water pressure deep under the sea, its spine is very thick and sturdy. Umbtail evolved from exposure to the moon's energy pulses.
