Feeding a shark is not easy. But here's how they do it at at Ripley Aquarium in Toronto. First the workers, or "aquarists," scoot the sea turtles out of the tank: each turtle has learned to swim towards its own colored stick. Then the workers feed all the small fish in the corners of the tank and along the bottom. Finally, with them all out of the way, the aquarists stick fish on a long pole and hold it over each shark. The sharks eat just 3 times a week, but chow down 1,000 pounds of fish in that time!
