Why Sharks Matter

Sharks help shape healthy ocean communities. Explore their role, discover what makes them vulnerable, and learn how thoughtful conservation can make a difference.

Shark facts

Ancient, diverse, and essential

Sharks are not one kind of animal with one story. Their long history and many forms reveal how deeply they are woven into life in the ocean.

More than 400 million years

Sharks were swimming in Earth’s oceans long before the first dinosaurs appeared on land.

Slow to recover

Many sharks grow slowly, mature late, and produce few young, so depleted populations may need a long time to rebuild.

Healthy sharks, healthy oceans

Why sharks matter to the whole ocean

Ocean life is connected through food webs. By influencing the abundance, health, and behavior of other animals, sharks help shape the communities around them. Their presence can support biodiversity and keep one part of an ecosystem from overwhelming another.

That balance can be difficult to restore once it is disrupted. Because many shark species reproduce slowly, losses may accumulate much faster than populations can replace them. Protecting sharks is therefore not only about protecting a single animal; it is one part of caring for the habitats and living communities that share the ocean.

2027 Poster Contest Sharks in Balance: Healthy Sharks, Healthy Oceans Discover how shark science, conservation, and young artists come together in this year’s Ocean Pals creative challenge.
A shark educator’s perspective Cristina Zenato Cristina’s work with Caribbean reef sharks combines close observation, education, and conservation. Her experience creates a natural bridge between learning why sharks matter and inviting young artists to express those connections through the poster contest. Meet Cristina Zenato

Stories and understanding

Looking beyond the familiar shark story

Peter Benchley: looking beyond Jaws A famous story can shape the way we see an animal. Peter Benchley’s years of diving and observing marine life helped turn his fascination with sharks into a commitment to conservation. His story invites us to look beyond fiction and consider how learning more can change the way we see—and protect—ocean life. Read the story
