Oarfish

A marine science instructor snorkelling off the southern coast of California this week discovered the carcass of a rare deep sea oarfish, one of the longest fish in the world.

The oarfish, which can grow to more than 50 feet (15 meters), is a deep-water pelagic fish, the longest bony fish in the world, according to the Catalina Island Marine Institute.

For the second time this year an oarfish, a rarely seen deep sea fish that has historically been considered a harbinger of doom, washed up on the California coastline.
