Did you know? Corals are animals 🤯
Corals consist of lots of little polyps, that look like tiny
anemones. A ring of tentacles surrounds a mouth, which leads to a
central stomach. Because coral belong to the same group of animals as
yellyfish, the cnidarians, they, too, posses stinging cells. These
cells, called nematocysts, are located in the tentacles. The tentacles
with their stinging cells are used to catch tiny prey from the water
column. As the polyps grow, they deposit a skeleton made of calcium
carbonate, which over time forms gigantic reef structures. These reefs
can get so big, they can be seen from space.
