Cetorhinus maximus

Basking Shark

Cetorhinus maximus

This slow-moving migratory shark is the second largest fish, growing as long as 40 feet and weighing over 5 tons.

It is often sighted swimming close to the surface, huge mouth open, filtering 2,000 tons of seawater per hour over its complicated gills to scoop up zooplankton.

Basking sharks are passive and no danger to humans in general, but they are large animals and their skin is extremely rough, so caution is urged during any encounters.

Importance to Humans

In the past, basking sharks were hunted worldwide for their oil.

meat, fins, and vitamin rich livers. Today, most fishing has ceased except in China and Japan.

The fins are sold as the base ingredient for shark fin soup. A “wet” or fresh pair of fins can fetch up to $1,000 in Asian fish markets while dried-processed fins generally sell for $350 per pound.

The liver is sold in Japan as an aphrodisiac, a health food, and its oil as a lubricant for cosmetics.

From a 4-ton (3629 kg), 27 feet (8.2 m) basking shark, a fisherman will get 1 ton of meat and 100 gallons (380 liters) of oil.

Interestingly, many tales of sea serpents and monsters have originated from sightings of basking sharks cruising single file, snout to tail, near the surface of the water.

More recently, the basking shark has sparked an interest in eco-tourism operations.

Conservation

As with other sharks, basking sharks are vulnerable to overfishing for several reasons.

They have a lengthy maturation time, slow growth rate and a long gestation period.

years

  • 1993 – It was reported that the global population of basking sharks had dropped by 80% since the 1950’s.
  • 1995 – A Barcelona Convention Protocol added the basking shark to its list of Threatened Species.
  • 1997 – The U.S. National Marine Fisheries Service banned the fishing for basking sharks in US Federal Atlantic waters.
  • April 1998 – The British Government announced a movement to protect the basking shark in UK waters, under Appendix II of CITES (The Convention on International Trade in Endangered Species of flora and fauna).

Geographical Distribution

The basking shark is a coastal-pelagic species found throughout the world’s arctic and temperate waters.

In the western Atlantic, it ranges from Newfoundland to Florida and southern Brazil to Argentina.

and from Iceland and Norway to Senegal, including the parts of the Mediterranean in the eastern Atlantic.

and from Ecuador to Chile in the eastern Pacific.

Biology

Distinctive Features
The basking shark is one of the most recognizable of all sharks.

Its massiveness, extended gill slits that nearly encircle the head and lunate caudal fin together help distinguish it from all other species.

It possesses a conical snout and numerous large gill rakers modified for filter feeding.

Its enormous mouth extends past the small eyes and contains many small, hooked teeth.

The basking shark has a very large liver that accounts for up to 25% of its body weight.

The liver is high in squalene, a low-density hydrocarbon that helps give the shark near-neutral buoyancy.

Taxonomy

Occasionally known as “sunfish” or “sailfish” in certain areas of the world, the basking shark is the only member of the family Cetorhinidae.

It was first described by Gunnerus in 1765 from a specimen from Norway and was originally assigned the name Squalus maximus.

Synonymous names include Squalus isodus Macri 1819, Squalus elephasLesueur 1822.

Squalus rashleighanus Couch 1838, Sqalus cetaceus Gronow 1854, Cetorhinus blainvillei Capello 1869.

Selachus pennantii Cornish 1885.

 

Cetorhinus maximus infanuncula Deinse & Adriani 1953 and Cetorhinus maximus normani Siccardi 1961).

The currently accepted scientific name is Cetorhinus maximus as assigned by Gunnerus in 1765.
