Sentences with phrase «marine sponges»
"Marine sponges" refers to a type of living creature that can be found in the ocean. They are not plants but are animals that don't have a backbone. They have a soft and porous body with many tiny holes. Marine sponges are important for the health of ocean ecosystems because they filter water and provide habitats for other small animals.
