What is Hexacorallia?

Hexacorallia is a group of animals that build pretty cool homes underwater, like tiny architects building cities.

Imagine you're playing with blocks. Each block represents a small creature called a polyp. These polyps work together to build big, beautiful structures, just like how kids stack blocks to make towers or castles.

In Hexacorallia, each polyp has six sides, kind of like a hexagon, which is a shape with six straight sides. That’s why they're called Hexacorallia (hexa means six, and corallia means coral).

Each polyp lives inside a little house it makes out of calcium carbonate, the same stuff your bones are made of! When lots of these polyps team up, they create big reefs or colonies. Some of them even form giant underwater cities that fish and other sea creatures call home.

These animals don’t use magic, just teamwork and tiny houses to make amazing structures under the ocean.
