The temperature of the Australian seawater was 28 degrees in November. This temperature started a very special process.

The corals of Australia’s Great Barrier Reef spawned. They released millions of eggs and sperm into the waters. Only a few people were lucky to see something like this. Scientists and tourists who saw it said that it was amazing.

This phenomenon has only been known for 30 years. Coral spawning usually happens at night.

Difficult words: spawn (release eggs or sperm), phenomenon (something which happens in nature).
