Could climate change, this years El Nino, changing patterns in the ocean's currents, have 'funneled' this prehistoric fish into shallow waters?
From National Geographic News
..a frilled shark swims at Japan's Awashima Marine Park on Sunday, January 21, 2007. Sightings of living frilled sharks are rare, because the fish generally remain thousands of feet beneath the water's surface. Spotted by a fisher on January 21, this 5.3-foot (160-centimeter) shark was transferred to the marine park, where it was placed in a seawater pool... ..the "living fossil" died hours after it was caught.
