Wanderlust World Wanderlust World Coral reefs cover less than 1% of the ocean floor yet support an estimated 25% of all marine species. Their complex three-dimensional structures create countless niches for life.
Thousands of fish species call reefs home: groupers, snappers, parrotfish, surgeonfish, angelfish, butterflyfish, wrasses, gobies, blennies, moray eels, seahorses, pipefish, and many more. Each occupies a specific feeding guild and microhabitat.
Corals themselves are colonial cnidarians. Alongside them thrive sponges, sea anemones, nudibranchs, octopuses, squid, crabs, shrimps, lobsters, sea urchins, starfish, and countless crustaceans and mollusks.
Reefs also host marine algae, seagrasses, sea turtles, sharks, and visiting marine mammals like dolphins, dugongs, and even whales. The labyrinth of crevices provides nursery grounds, hunting territories, and refuge from predators.
This staggering diversity underpins reef resilience, fisheries productivity, coastal protection, and tourism economies. Protecting reefs safeguards a disproportionate share of ocean life and human well-being.
