A sea creature straight out of a nightmare washed up onto the shore of a Southern California beach recently. Its appearance was so ghastly that the images of it posted to Reddit were marked not safe for work.

The original poster shared they discovered the dead marine animal near Dana Point, California, and it was that detail along with the clear photos that helped identify the unsightly organism.

Tim Daly, a California Department of Fish and Wildlife spokesperson, told SFGATE, he agreed with the majority of the comments on Reddit identifying the bloated animal.

It’s likely a dead moray eel, though this particular one “looks a little bleached out from being dead.”

It’s not uncommon to find moray eels living in the water off the coast of Southern California as they are known to live among reefs in shallow water.
