Tiger sharks, as with other sharks, have small pits on the side of their upper bodies which hold electrical sensors called the ‘ampullae of lorenzini’, enabling them to detect small muscle movements of other creatures, allowing them to hunt in darkness. The Tiger sharks head is somewhat wedge-shaped, which makes it easy for the shark to turn quickly to one side. The distinguishing dark spots and stripes are most outstanding in young sharks and fade as the shark matures. The Tiger sharks skin can typically range from a blue or green hue to light with a white or light yellow underbelly. The largest Tiger shark specimen was 7.3 metres (24 feet) and is a contender for the largest carnivorous fish alongside the great white shark. The heaviest specimen recorded to date, a shark caught in Newcastle, NSW, Australia in 1954 and measuring a mere 5.5 metres (18 feet), weighed 1,524 kilograms (3,360 pounds).
Mature sharks average 3.25 metres (11 feet) to 4.25 metres (14 feet) in length and weigh 385 to 909 kilograms (850 to 2000 pounds). This family includes some other well known sharks such as the blue shark, lemon shark and bull shark. It is the largest member of the Carcharhinidae family, commonly referred to as requiem sharks. The Tiger shark is a member of the order Carcharhiniformes members of this order are characterized by the presence of a nictitating membrane over the eyes, two dorsal fins, an anal fin and five gill slits. The Tiger shark is often found close to the coast, in mainly tropical and sub-tropical waters, though they can reside in temperate waters.
It is the only member of the genus ‘Galeocerdo’. The Tiger shark is found in many of the tropical and temperate regions of the worlds oceans and is especially common around islands in the central Pacific. The Tiger Shark is one of the largest sharks in the world.
