These sharks use their tails to push them trought the water and their fins to keep themselves balanced. They must constantly swim or else they will sink.
Gws (Great White Shark) are predatory (eats other animals fish etc.) Their food includes other sharks, fish, sea lions, seals, turtles and small whales. Gws are also seavengers eating animals already dead (carrion). Despite having teeth gws do not chew their food but swallow whole pieces ripped off their victim by their teeth.
The gws swiftly attacks its prey from below taking a bite and letting the victim bleed to death. To locate its prey the gws uses its very excellent sense of smell (especially of blood) and ability to sense “electrical charges” given off by muscle movements.
The great white shark sometimes called the “great white”, and there are over 600 species of sharks and rays with the gws belonging to a group of fast-swimming sharks called mackerel sharks.
