![]() In deuterostomes the anus forms first followed by the mouth. In protostomes the mouth opening is the first to be formed later followed by the anus. The major difference between protostomes and deuterostomes are how they develop in the early embryo stages. What is the difference between a Protostome and a Deuterostome quizlet? What is the main characteristic that deuterostomes share with protostomes?įormation of mouth and anus The defining characteristic of the deuterostome is the fact that the blastopore (the opening at the bottom of the forming gastrula) becomes the anus, whereas in protostomes the blastopore becomes the mouth. ![]() Deuteronomy, “second book of the law”), including Echinodermata and the ancestors of the Chordata, the oral end of the animal develops from the second opening on the dorsal surface of the animal the blastopore becomes the anus. In the deuterostomes (“second mouth”: cf. What happens to the blastopore during Deuterostome development? The blastopore becomes the anus and the mouth develops as the second opening. What does the blastopore become in protostomes and deuterostomes? However, in protostomes, the mouth is created from the blastopore. In deuterostomes, the blastopore transforms into an anus, and another cavity on the opposite side creates a mouth. Thus, the difference between protostomes and deuterostomes lies in the position of their organs.
