Do you have information about the recent ocean creature that was found?

Question

It had prehistoric features and only lived a short time after being captured.

Answer 1

A frilled shark was filmed in Japan last week. This is a rarity because the shark lives in very deep water. Fishermen in the town of Shizuoka, south of Tokyo, spotted the shark and notified the local Awashima Marine Park. Marine park staff captured the shark and filmed it in a seawater tank. The frilled shark normally stays at depths of between 2000 and 3000 feet, and this female may have moved towards the surface because it was already ill. Frilled sharks are sometimes caught in fishing nets, but are rarely seen alive due to the depth of their habitat. This one lived only a few hours after it was captured. The reference to prehistoric features is because the frilled shark has remained virtually unchanged since prehistoric times.

Answer 2

It was some kind of shark that normally lives thousands of feet below the sea. It was a "living fossil" type creature- unchanged for long time, like horsedhoe crab.
It was not a new scientific finding.

Answer 3

A coelacanth?
