Other strange items found in the stomachs of these massive creatures include beer bottles, bags of potatoes, coal, dogs, overcoats, a driver's license, a cow's hoof, the antlers of a deer, undigested lobsters, and a chicken coop with feathers and bones still inside. When a tiger shark's stomach becomes too full of indigestible junk, it regurgitates and gets rid of it all. Though the tiger has excellent eyesight, it relies mostly on its acute sense of smell, which enables it to detect the faintest traces of blood. Their electroreceptors are sensitive to low-frequency pressure waves produced by movements in the water, allowing these sharks to track prey in the absence of light. One of the male's pelvic fins is inserted into the female's genital opening as a guide for the sperm.
Males often use their teeth to hold the females motionless during mating.
Behavior Tiger sharks are solitary and nomadic. They often travel up to fifty mile in a day, stopping only to feed. Tiger sharks can attain speeds greater than 20 miles an hour. Tigers tend to stay in deep waters on the fringes of reefs. Habitat Tropical and sub-tropical seas with seasonal excursions into warm temperate waters.
