日本語クロスワード - Coral

Corals are tiny living creatures called polyps. They live in shallow waters in warm seawater, where the temperature does not drop below +18 degrees and there is enough light. polyps are very tender, but their body is covered with a hard shell. Polyps are predators, hiding during the day and protruding from the shell at night and catching microorganisms floating by with their tentacles
