WitrynaMetamerism produces specialization in regions of the body for specific functions. The regional specialization is called tagmatizafion. In arthropods,, body regions are called tagmata, tagmata are specialized for feeding and sensors perception, locomotion and visceral functions. ---------------------------- ---------------------------- WitrynaThe cells making up a hydra’s body are relatively simple. Hydra has two main body layers. The outer layer is the epidermis (like our skin) which can secret a protective layer (hydramacin) against bacterial infection.
