Rare Shark of the Deep:-“Frilled Shark”

With its elongated, eel-like body and strange appearance, the frilled shark has long been likened to the mythical sea serpent. The head is broad and flattened with a short, rounded snout. The nostrils are vertical slits, separated into incurrent and excurrent openings by a leading flap of skin. The moderately large eyes are horizontally oval and lack nictitating membranes (protective third eyelids). The very long jaws are positioned terminally (at the end of the snout), as opposed to the underslung jaws of most sharks. The corners of the mouth are devoid of furrows or folds.

A frilled shark, rarely seen alive because its natural habitat is 600 metres or more under the sea, photographed by the Awashima Marine Park.

The tooth rows are rather widely spaced, numbering 19–28 in the upper jaw and 21–29 in the lower jaw. The teeth number around 300 in all; each tooth is small, with three slender, needle-like cusps alternating with two cusplets There are six pairs of long gill slits with a “frilly” appearance created by the extended tips of the gill filaments, giving this shark its name. The first pair of gill slits meet across the throat, forming a “collar”.


On January 21, 2007, a Japanese fisherman discovered a 1.6 m (5.2 ft) long female alive at the surface, perhaps there because of illness or weakness from the warm water. It was brought to Awashima Marine Park in Shizuoka, where it died after a few hours. Garman, and numerous authors since, have advanced the frill shark as an explanation for sea serpent sightings. Because of the shark’s modest size, some cryptozoologists have posited the existence of a giant relative, particularly as larger Chlamydoselachus species are known from the fossil record.

    Truth is stranger than fiction, magsx2! A Hollywood special effects person couldn’t dream up something as bizarre as ths.

      Hi malc50,
      It is weird looking that’s for sure. It is such a shame that it was dieing, but then again if it wasn’t, it would not have come to the surface, and we wouldn’t have these pictures or video’s.

    My first reaction: Photoshop. But then I remembered finding my old baby photos.

      Hi gregoryno6,
      Ahh see not everything is photoshoped, not even your baby photos 🙂
      This is a fully documented species, and was even in the Marine Park for a very short time before it died. I do a fair bit of research before I post anything like this, and hopefully (touch wood) the research should reveal if it is true or not.
