Sharks


Pacific Mako Shark

One of the most active sharks, it leaps repeatedly when hooked and is, consequently, a popular quarry for shark fishermen. The Mako is involved in attacks on boats more frequently than any other species.
Thresher Shark: Distinguished by the long (up to 3.3 m) upper lobe of the caudal fin which is used to strike whip-like blows at its prey.
Hammerhead: The eyes are located at the outer tips of the head It grows to 4.5 m or more.
Mako: Perhaps the most beautiful of the sharks. The back is a deep blue, the underside a glittering white. It grows to 455 kg and up to 3.6 m long.
Greenland Shark: A very lethargic creature and one of the few sharks to inhabit polar waters year-round.
Great White Shark: The most dangerous of all the sharks. The largest taken measured 6.3 m and weighed 3,315 kg. It is very aggressive.
