With its gaping, tooth-filled mouth and its slender, eel-like body, it’s not hard to see why scientists think the frilled shark may have inspired ancient tales of sea monsters. Looking like something out of a nightmare, the deep-sea creature is rarely seen. But fishers in Australia pulled one up.
The frilled shark is often called a “living fossil” because it is thought to have changed little in about 80 million years. The fish also bears a resemblance to ancestor species that lived during the time of the dinosaurs.
Australian media reported that a fishing trawler pulled up a two-metre frilled shark in waters near Lakes Entrance off southeastern Victoria, Australia.
Simon Boag of Australia’s South East Trawl Fishing Association told the Australian Broadcasting Corporation that no local fisher had ever seen the creature before. “It does look 80 million years old,” Boag told the ABC. “It looks prehistoric. It looks like it’s from another time!”
“It has 300 teeth over 25 rows, so once you’re in that mouth, you’re not coming out,” he said.
The shark "was on its last legs" when it made it to the surface, Boag told National Geographic.
Boag said the frilled shark was caught in about 1,000 metres of water. The species has previously been found at depths up to 1,500 metres but is generally thought to live no deeper than 1,200 metres.
Australia’s national science agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), confirmed that the specimen was a frilled shark.
Frilled sharks are occasionally seen at the surface, mostly when they are sick. Most known specimens have been around two metres in length. But the California-based MarineBio Conservation Society says that the netting of a 7.6-metre shark related to the frilled shark in 1880 “suggests there may be some giant frilled sharks in the sea that could be taken for sea serpents.”
In 2007, a 1.6-metre frilled shark was found in shallow water in Japan and transferred to a marine park. It died hours after being caught.
