👉 Ichthyomorpha is a group of marine animals that includes fish, sea urchins, and certain types of crustaceans. These animals are characterized by their unique body structure and functions, such as swimming through water or using their gills to extract oxygen from the air. The term "ichthyomorpha" refers to all these different groups together, which were once considered separate groups until they were merged with other marine animals in 1968.
