Question

do coelentrates have three germ layers?​

Answer 1

In the case of cnidarians there are two layers: the endoderm and the ectoderm. ... But cnidarians do not have this middle layer. Germ layers develop during gastrulation. In cnidarians, the endoderm will form the internal tissues and structures such as the gastrodermis and gastrovascular cavity called the coelenteron.
