Staghorn coral

Deep in the warm, sunny waters of the Caribbean Sea grows one of the ocean’s great builders: the staghorn coral. It has long, branching arms that reach upwards through the water, and they look so much like the antlers of a deer that this is exactly how the coral got its name. Its branches can grow taller than a grown-up is tall.

A coral may look like a plant or a rock, but it is really made of hundreds of tiny animals called polyps, all living together as one. These little polyps build a hard, stony skeleton beneath them, and over many years the branches grow and grow. Staghorn coral is one of the fastest-growing corals of all, stretching a little taller every single year.

As they grow, staghorn corals join up to build big, beautiful reefs. These reefs are like busy underwater cities, full of nooks and crannies. Baby fish, shrimp, crabs, and all sorts of sea creatures come to live among the branches, using them as a home to shelter in and a safe place to hide from bigger animals.

Sadly, staghorn coral is now Critically Endangered, which means there is much less of it than there once was. Warmer seas, storms, and coral sickness have made life hard for it. But there is good news: kind scientists and volunteers grow tiny pieces of staghorn coral in special underwater nurseries and gently plant them back onto the reefs.

Thanks to all these helpers, new staghorn branches are slowly growing again in places where the coral had almost disappeared. Every little piece that is planted gives the reef, and all the creatures that depend on it, a brighter and more hopeful future beneath the waves.
