What is the difference between tentacles and stinging cells?
Stinging cells are cells that "sting" and pour toxins into the bloodstream, and tentacles are long appendages that have no relation whatsoever to stinging cells.
Hydras respirate via diffusion, oxygen in the comparatively oxygen-rich surrounding water passes through their epidermis to their comparatively oxygen-deficient internals. They do not breathe at all.
Stinging cells are called cnidocytes, as in all members of the Cnidarians which includes jellyfish, sea anemones, and corals.
