Sea cucumber

Sea cucumbers are an animal that lives on the ocean floor. They look like a cucumber with lots of feet and are typically found on coral reefs in the ocean. Sea cucumbers eat tiny food pieces like algae and plankton that are found in the water. Their bodies are made of hard plates that help them defend against predators, and their feet help them move around in search for food.
