Sharks

Sharks are a type of fish. They live in the waters of Club Penguin. Sharks are predatory animals, meaning that they hunt for their food, which consists of animals with a lot of fat (blubber), such as seals, whales, and ('gulp') Penguins.

Background
Sharks are native to Antarctica. They don't have a good reputation with the animals they sometimes eat, but the sharks are necessary to the ecosystem, helping to balance out the food chain. Sharks have no enemies except for orcas, who eat shark.

Involvement
Sharks enjoy feasting of penguins as much as penguins like eating fish, which is why penguins are trying to figure out a way to keep the sharks out of the beaches. Some ways are trying to put chemicals in the water which repel sharks. A cleaner way is to put electromagnetic charges which will tingle the shark's sensory organs and cause them to go away.

Jellyfish use sharks as beasts of burden. Many farmer jellyfish use sharks to pull their plows and to round up fish. However, crabs enjoy pinching sharks, which make them angry and do their job wrong. Sharks also are used to pull carriages as a way of transportation, but now 75% of Jellyfish own cars. Sharks don't like eating jellyfish because they have no fat and have painful stingers.

Trivia

 * Sharks like eating worms too. In fact a shark will eat just about anything, like crabs, clothing, soil, and garbage. But not jellyfish.
