Thresher Sharks
There are three species of tresher sharks - the common, the pelagic, and bigeye thresher.
Thresher Sharks are easily recognized by their extremely long tails. the upper lobe, or part, of a Tresher's tail can be up to 50 percent of the whole shark's body length.
include the tail, Thresher Sharks can grow up to 6 meters long.
Thresher Sharks use their amazintg tails to round up shoals of small fish such as sardines or herrings. Then they stun the fish by beating ( or 'treshing' ) them with their tails, before eating them.
Although Thresher Sharks are big, their mouths are small so they only eat small prey.
Thresher Sharks hardly ever attack humans. But they have been knowing to injure fisherman by hitting them with their tail.
" Thresher Sharks have reputation for being very cunning. Because of this, the ancient Greeks and Romans called them ' Fox Sharks' ''.
