Question

please tell me what is the animal named hydra?

Answer 1

Hydras are simple invertebrates, with two layers of body cells. They live in the fresh water. Their body is radially symmetric. They have a central cavity that serves to both take in food and expel waste. Being Cnidarians they have stinging cells on their tentacles. They are hydrozoa, and belong to the same order as the polyps. Most hydras aremicroscopic in size. Hydras can be found in almost any unpolluted body of water. Hydras reproduce in an agamete way called budding. In budding, the offspring forms as a lump on the parent and eventually becomes big enough to break off and live by itself. They can move if they need to by a kind of slow somersaulting motion.
