Typically, basking sharks reach 7.9 m (26 ft) in length. It is usually greyish-brown, with mottled skin, with the inside of the mouth being white in colour. The caudal fin has a strong lateral keel and a crescent shape. Other common names include bone shark, elephant shark, sailfish, and …

2024年11月27日 · Cartilaginous Skeleton. The basking shark’s skeletal structure is primarily composed of cartilage rather than bone, a characteristic trait shared by all members of the class Chondrichthyes.

All sharks are elasmobranchs. The skeleton of elasmobranch fish is made of cartilage, a material not unlike the hard gristle found around mammalian joints. This might be partially calcified, but not to the same extent as in the bony (teleost) fishes.

One very big difference is the basking shark’s humungous mouth, which can open up to 1.8m wide and is almost skeleton-like in appearance inside.

The Basking Shark is the largest of the lamnoids and a true titan among sharks. Individuals up to 30 feet (9 metres) long are encountered frequently. The largest Basker recorded in the scientific literature measured some 37.7 feet (11.5 metres) long and weighed roughly 5 tons (4.5 tonnes).

A sharks skeleton differs from that of other fish because it is composed entirely of cartilage. Cartilage is a strong and durable material but also light weight and relatively flexible. These characteristics aid in the general movements of the shark in a variety of ways.

Skeleton. The skeleton of elasmobranchs is made of cartilage. Vestigial ribs give no support. The skeleton may be partially calcified to some extent with calcium phosphates and carbonates, particularly in the vertebral column. The calcified cartilage is not a true bone. The cartilage of a shark's skeleton may be important in future cancer research.

2023年3月22日 · One Basking Shark was found with a liver that weighed over 2,000 lbs (940 kg)! For comparison, human livers usually only weigh 3 lbs (1.3 kg). A shark’s massive liver, along with their light skeleton, keeps them afloat.

2008年1月1日 · The skeleton of the basking shark is cartilaginous with varying degrees of calcification throughout, but like that of other sharks, these structures are not ossified (Kunzlik, 1988). The paired sexual organs (claspers) of male sharks are located ventrally at the base of the paired pelvic fins and these become progressively calcified with maturity.

2023年1月1日 · Here we review the literature on the basking shark (Cetorhinus maximus, Gunnerus, 1765), well known as the second largest extant shark (and fish) species globally.
