Rare, deep-sea oarfish have been washing ashore, and they've got ecologists and superstitious fishermen worried:

Oar fish live in the depths of the ocean, surfacing infrequently when they are sick or damaged. In Japan it is believed the appearance of oar fish means an earthquake is imminent. Since November, over 19 of the rare fish have washed up on the shores of Japan. The animal is thought to be the origin of ancient mariner myths of sea serpents.
