👉 Dinophysales are a group of animals that belong to the order Dipsida, which is also known as "fish" or "vertebrates." These animals have a single ciliated cell called a myelin layer and are characterized by their specialized circulatory system. Their primary role in the aquatic environment is to facilitate gas exchange through their gills, which are covered with cells that contain lipids that serve as a pump for gases like oxygen and carbon dioxide.
