Healthy coral reefs, known for their brightly colored spiny and soft layers, may act as critical refuges and food sources for hungry sharks swimming through Australia's Great Barrier Reef, reports a new 10-year study that captured underwater footage of sharks.

in environmental science at James Cook University in Queensland, Australia, told Live Science in an email. "It's a simple but powerful message."
