Protostomes are a group of animals characterized by a specific pattern of development, including the mouth forming before the anus during embryonic development. Clams, earthworms, crabs, and spiders are all examples of protostomes. Milkfish, however, are not protostomes; they are part of the group known as deuterostomes, which includes vertebrates like fish, birds, mammals, etc., where the anus forms before the mouth during development.
