After cleavage, the dividing cells which called  morula, becomes a hollow ball, called blastula, that develops a hole or pore at one end.

In bilateral animals, the blastula that is a hollow ball develops in one of two ways which divides the whole animal kingdom into two halves becomes the mouth of the animal, it is a protostome. The protostomes include most invertebrate animals, such as worms, insects, or molluscs, the blastula changes into a more differentiated structure known as gastrula.
