Lesson Excerpt:
If you’ve ever been to the sea side and played in the rock pools, you have probably seen anemones. They may have been attached to a rock, or even to the carapace, or shell, of a crab. With their colorful tentacles anemones are sometimes called the flowers of the sea. But even though they look like plants, they are actually animals. Anemones belong to the same family as jellyfish and coral. The family name is Cnidaria which comes from a Greek word meaning stinging nettle. All cnidaria have stinging cells. The tentacles of the anemone which look so pretty are sticky and covered with tiny tubular harpoons. The tubules are kept coiled up in poisonous cells called nematocysts. Anemones fire these poisonous harpoons at their prey to paralyze it so they can eat it. Anemones are carnivorous which means that they eat small animals such as shrimps instead of vegetation.
