Crayfish, like other arthropods, develop from three embryonic tissue layers: the ectoderm, mesoderm, and endoderm. These layers give rise to various tissues and organs throughout their development. The ectoderm forms structures such as the exoskeleton and nervous system, while the mesoderm contributes to muscles and the circulatory system, and the endoderm develops into the digestive tract.

How many embryonic and adult tissue layers and found in jellyfishhydrasand sea anemones?
Jellyfish, hydras, and sea anemones are all part of the phylum Cnidaria and possess two embryonic tissue layers: the ectoderm and endoderm. These organisms are classified as diploblastic, meaning they have only these two primary germ layers. In contrast to triploblastic organisms, they do not have a mesoderm layer. As adults, they maintain these two tissue layers throughout their life cycle.
