Animals in the sponge group, known as phylum Porifera, include various species of sponges such as sea sponges, glass sponges, and demosponges. These animals are multicellular but lack true tissues and organs, with specialized cells performing different functions within their bodies. Sponges are filter feeders that live in aquatic environments, ranging from freshwater to marine habitats.
The organs you can't live without are the heart, lungs, brain, and liver. These organs are essential for the body to function properly and sustain life.
