can hydra be called an immortal organism? if yes, justify your answer giving complete details

​Hydras belong to the phylum​ Cnidaria which can regenerate, allowing them to recover from injury and to reproduce asexually. Hydras are simple, freshwater animals displaying a radial symmetry and no post-mitotic cells. All hydra cells continually divide and it has been suggested that hydra do not undergo senescence, and can thus be called biologically immortal.
