Phylum Placozoa: Plate Animals

The video explores the phylum Placozoa, highlighting its unique characteristics, evolutionary relationships, and habitat. Placozoa are simple, diploblastic marine animals with no symmetry, organs, or nervous systems. They move using cilia and feed by external digestion. Their evolutionary position is debated, with some analyses suggesting they are a sister group to Cnidarians. Placozoa reproduce asexually and have remarkable regenerative abilities. Despite their simplicity, they continue to intrigue researchers due to their unique features and potential insights into early animal evolution.
