How does a hydra protect itself?

Answer 1

A hydra protects itself primarily through its stinging cells called cnidocytes, which contain specialized structures called nematocysts that can inject toxins into predators. When threatened, the hydra can quickly retract its tentacles and use these stinging cells to deter or incapacitate potential threats. Additionally, its ability to regenerate allows it to recover from injuries, enhancing its survival against predators. The hydra's simple body plan and ability to move away from danger also contribute to its defensive strategies.
