Hello,

----- Hydra Generally perform asexual reproduction during normal conditions.

- When food is plenty, many Hydra reproduce asexually by budding. The buds form from the body wall, grow into miniature adults and break away when mature.

- When a hydra is well fed, a new bud can form every two days.

----- When conditions are harsh, often before winter or in poor feeding conditions, sexual reproduction occurs in some Hydra .

--- Swellings in the body wall develop into either ovaries or testes.

---The testes release free-swimming gametes into the water, and these can fertilize the egg in the ovary of another individual.

---- The fertilized eggs secrete a tough outer coating, and, as the adult dies (due to starvation or cold), these resting eggs fall to the bottom of the lake or pond to await better conditions, whereupon they hatch into nymph Hydra.

----- Some Hydra species, like Hydra circumcincta and Hydra viridissima, are hermaphrodites[11] and may produce both testes and ovaries at the same time.

I hope you find the answer helpful

Thank you
