This is a characteristic of deuterostomes, a group of animals that includes echinoderms, chordates, and some other minor phyla. In deuterostomes, the blastopore becomes the anus and the mouth forms later, from a secondary opening. In contrast, in protostomes (which include molluscs, annelids, and arthropods), the blastopore becomes the mouth and the anus forms secondarily.
