I am a loner and I love to travel. I can swim up to 50 miles (80 km) a day at speeds over 20 mph (32 km/hr). During the day, I am sluggish and spend my time in deeper water. At night, you can find me hunting on the reef. Because I'm active at night, I am nocturnal.
I am the largest predator on the reef. I have excellent vision, but my sense of smell is even better! I can sniff out the tiniest amounts of blood in water. I even have special cells called electroreceptors that help me to detect movement in the water. All of these senses make me one of the best hunters in the world! I will circle my prey and trap it before I attack it with my rows of razor sharp teeth.
I am NOT a picky eater. I eat everything (and I mean everything)! I will eat lobsters, octopi, crabs, squids, fish, poisonous fish, sharks, turtles, sea snakes, sea birds, dolphins, whales, and even other tiger sharks! But it doesn't stop there! I also eat non-sea animals and even trash. Here are some strange things that have been found in my stomach: chickens, dogs, cows, deer, humans, bottles, plastic bags, coal, coats, drums, and a chicken coop! When I have too much non-living junk in my stomach, I throw it up and keep looking for more food. Meat is my favorite thing to eat, but because I will eat anything I am an omnivore.
In some places, people take too many fish out of the reef for humans to eat. This is called overfishing. I can't live in places that are overfished because there is not enough food for me to eat!
