When we ask kids about sharks, their first response is often fear or fascination. Either way, they are often very passionate about the subject, which provides a great basis for learning. Sharks play a crucial role in ocean ecosystems, making them an ideal subject for cross-curricular learning in primary classrooms – integrating science, geography, literacy, and citizenship.

Why Sharks Matter in Ocean Ecosystems

Sharks are apex predators. As top-level predators, they help maintain the balance of marine life, supporting the health of coral reefs, seagrass beds, and other critical habitats. Without sharks, our ocean ecosystems can become unstable, leading to the overpopulation of some species and the collapse of others.

Sharks are Guardians of the Ocean

Movies and myths often cast sharks as villains, but they’re essential guardians of the ocean. Teaching kids about sharks helps bust common myths and builds respect for these incredible animals. It also opens up conversations around the marine food chain, shark conservation, and the importance of protecting ocean biodiversity.

Shark Resources from Ocean Life Education

What Role Do Sharks Play in the Ecosystem?

1. Balance Marine Populations
   Sharks regulate the populations of prey species like rays and smaller fish, preventing them from overgrazing critical habitats like seagrass and coral reefs.
2. Support Ocean Biodiversity
   By preying on weak or sick individuals, sharks help keep marine species healthy, promoting genetic strength and ecological balance.
3. Drive Evolution
   Sharks influence the behaviour and evolution of other marine animals. Their presence encourages adaptive traits and survival strategies in prey species. Watch our Shark Adaptation Mini Video here and check out our Adaptation themed programs.
4. Indicate Ocean Health
   A thriving shark population is a key sign of a healthy ocean. Sharp declines in shark numbers often signal wider problems in the marine food web, with long-term consequences for both wildlife and human communities.

Australia’s Great Barrier Reef: A Unique Marine Habitat at Risk

Located along Australia’s northeast coast and spanning over 2,300 kilometres, The Great Barrier Reef, is one of the world’s most complex and diverse ecosystems.  It is home to over 1,500 species of fish, 400 types of coral, and a diverse range of other marine creatures like sea turtles and dugongs. This beautiful and vibrant reef is an essential marine habitat that supports abundant marine life, protects Australia’s eastern coastlines from erosion, and contributes to global climate regulation.

However, this remarkable ecosystem is under threat due to human impact. Climate change, pollution, and overfishing are causing severe disruptions, including coral bleaching and the destruction of critical habitats. If we don’t act soon, the survival of the Great Barrier Reef’s diverse species—and the livelihoods of Australian communities that rely on it—will be at risk.

The Effect of Human Impact on Australian Marine Ecosystems – Coral Bleaching

Coral bleaching occurs due to rising ocean temperatures. Human Impact contributes to this climate change, as pollutants from vehicles and factories create an insulative layer in our atmosphere. Persistently warmer water temperatures cause corals to expel the algae that provide them with food and vibrant colours. Without these algae, corals become vulnerable and they eventually die, leaving behind a bleached, lifeless coral reef. Temperature rise isn’t the only problem—ocean acidification, driven by increased carbon dioxide levels, also weakens coral skeletons, making them more susceptible to damage.

Marine ecosystems are disrupted by the loss of coral reefs and this in turn harms local economies, including tourism and fishing industries that depend on these habitats for healthy fish stocks.

Polar Bears and Habitat Loss: The Impact of Melting Ice

The melting of polar ice caps is one of the most visible effects of human impact. These ice caps provide critical habitat for polar bears, who rely on the sea ice for resting, hunting, and breeding. As ocean temperatures rise, polar bear’s ice habitat is rapidly disappearing, causing them to need to travel and swim longer distances to find food. This can lead to exhaustion and starvation.

This reduction in the volume of ice also brings polar bears into closer contact with humans as they search for food in populated areas inland, increasing the potential for conflict. If global temperatures continue to rise, polar bears and the Arctic ecosystem could be in jeopardy .

2025 was named the UN International Year of Glacier’s Preservation. This is to highlight the importance of glaciers and the fact that they are disappearing at an alarming rate,

How Schools Can Help Protect Habitats and Ecosystems

At Ocean Life Education, we partner with Australian schools to teach students about the importance of protecting habitats and ecosystems. Human impact—such as plastic pollution, overfishing, and habitat destruction – can harm these ecosystems, but small changes in our daily lives can make a difference.
