This natural wonder is so vast it can be seen from space. The reef is home to an incredible diversity of marine life, including over 1,500 species of fish, over 400 types of corals, and dozens of species of sharks and rays.
Question 3: What are coral reefs made from?
- Phytoplankton
- Polyps
- Tentacles
Correct Answer: Polyps
Fact: Polyps are tiny, soft-bodied organisms. They secrete calcium carbonate skeletons which accumulate over time, forming the structure of coral reefs. Coral polyps live in colonies, and each polyp attaches itself to a hard surface, like rocks or old coral skeletons. As they grow and reproduce, they create intricate and diverse reef formations.
