Now, this is pretty cool
From CNN:
A species of shark rarely seen alive because its natural habitat is about 2,000 feet under the sea was captured on film by staff at a Japanese marine park this week.
Marine park staff caught the 5 foot (1.6 meter) long creature, which they identified as a female frilled shark, sometimes referred to as a "living fossil" because it is a primitive species that has changed little since prehistoric times. (Watch divers swim with bizarre, ailing shark Video)
The shark appeared to be in poor condition when park staff moved it to a seawater pool where they filmed it swimming and opening its jaws.
Unfortunately, it died a few hours later. Still, it is pretty wild to see a frilled shark at all.
