A Frilled shark was found by a trawler in the waters near Lakes Entrance in Victoria’s Gippsland Australia.
The shark was caught at a depth of 2,200 ft.
According to Wikipedia they can be found at a depth ranging from 160- 660 feet in Japan.
Here is some more info from the article.
Seldom observed, the frilled shark may capture prey by bending its body and lunging forward like a snake. The long, extremely flexible jaws enable it to swallow prey whole, while its many rows of small, needle-like teeth make it difficult for the prey to escape. It feeds mainly on cephalopods, leavened by bony fishes and other sharks. This species is aplacental viviparous: the embryos emerge from their egg capsules inside the mother’s uterus where they survive primarily on yolk. The gestation period may be as long as three and a half years, the longest of any vertebrate. Litter sizes vary from two to fifteen, and there is no distinct breeding season. Frilled sharks are occasional bycatch in commercial fisheries but have little economic value. The International Union for Conservation of Nature has assessed it as Near Threatened, since even incidental catches may deplete its population given its low reproductive rate. This shark, or a supposed giant relative, is a suggested source for reports of sea serpents.
