Oarfish are deep-water denizens that are rarely seen. But because of their long, slender appearance, and their bright-orange dorsal fins and manes, they helped spawn myths of sea serpents and sea monsters among ancient mariners.
They've been known to reach lengths of 30-plus feet.
Oarfish inhabit the world's oceans but are found in the dark depths between about 600 and 3,000 feet. On the rare occasions one is seen on or near a beach--this happens very rarely and sporadically--it's either sick or injured, dying or already dead.
