Q. Development of blastopore into anus is seen in:

EAMCETEAMCET 1999

Solution:

When a blaslopore gives rise to anus this condition is called deuterosiemia. The animals of phylum- Echinodermata to mammals are deuterostomes. Because Ophiolhrix is an echinodermate, in this blastopore gives rise to anus. Hydra, Octopus and Nereis are proiostome animals.
