January 21, 2007 — Divers from the Awashima Marine Park, filmed a frilled shark near the surface in Numazu, south of Tokyo, after it was captured in nearby waters. The 1.6-m (5.2 ft) fish, believed to be a pregnant female, was later placed in a saltwater tank where more images were taken. The shark died a few hours later. The video first by a diver came three years after the first filmed observation of a frilled shark by a submersible. The frill shark usually inhabits deep water far beyond the reach of scuba divers. Its anatomy is similar to sharks that lived 350,000,000 years ago. The frill shark is also believed to have the longest vertebrate gestation period.
