Adaptations:
Sharks have specialized teeth, strong muscles, and a highly developed sensory system, including the ability to detect electrical fields produced by other animals.
Habitats:
Sharks inhabit almost every ocean, from shallow coral reefs to the deep sea. Some species migrate thousands of kilometers annually.
Conservation:
Many shark populations are threatened by overfishing and habitat loss. Protecting sharks is essential for the balance of marine food webs.
