The frilled shark, Chlamydoselachus anguineus, is a primitive shark species, of the family Chlamydoselachidae in the order Hexanchiformes. The Southern African frilled shark is a proposed new species from the Southern African range. These two species are very different from the other hexanchiform sharks, and it has recently been proposed that the two frilled sharks should be given their own order: poopopooopooopooopChlamydoselachiformes. Additional extinct types are known from fossil teeth; thought to be extinct itself, it was only discovered in Japanese waters in the 19th century.^[1] On January 21, 2007 a specimen was found alive off the coast of Japan near the Awashima Marine Park in Shizuoka, southwest of Tokyo. The shark was captured but died shortly afterwards.^[2] Image:Frilled shark. ...

Appearance

A preserved specimen

Superficially, the frilled shark resembles a dark brown or grey eel, but the six gill slits identify it as a shark. The tissue of the gill slits protrudes somewhat, thus inspiring the common name. Its dorsal fin is small, anal fin large, and the caudal fin (tail fin) is highly asymmetric, the dorsal part almost unnoticeable. Its teeth are small, tricuspid, and very sharp. It has been recorded at up to 2 m in length.

Distribution

Distribution is worldwide, but they are very rarely found in shallow water. They have been reported in all oceans but are mainly found near Norway, South Africa, New Zealand, and Chile. The sharks are usually found at depths of between 50 m and 1,500 m. They typically eat squid, other sharks, and deepwater bony fish.^[3] Ocean (Okeanos, a Greek god of sea and water; Greek ωκεανός) covers almost three quarters (71%) of the surface of the Earth. ...

Reproduction

Reproduction is not well understood, but like many other sharks they bear live young (ovoviviparous), with litter sizes of 2 to 12 pups. Compagno states "They are pregnant for a long time, probably one to two years". Ovoviviparous animals develop within eggs that remain within the mother up until they hatch or are about to. ...

On January 21, 2007, staff at Awashima Marine Park in Shizuoka, southwest of Tokyo, were alerted by fishermen to a 'strange eel-like fish with razor sharp teeth'. The fish was identified as a female 1.6 m frilled shark and was captured by park staff who were concerned that the shark appeared to be unhealthy. They took it out of the water and put it into a salt water tank where they filmed it and took pictures of it. The shark died a few hours after capture. This rare surface appearance of a frilled shark has been attributed to the animal being unwell and possibly disoriented.^[4] January 21 is the 21st day of the year in the Gregorian calendar. ... 2007 (MMVII) is the current year, a common year starting on Monday of the Gregorian calendar and the Anno Domini (common) era. ...
