Detailed explanation-1: -The seasonal timing of sexual reproduction is a way of helping the species survive over the winter. This is because the fertilised eggs have a tough shell or covering and can form a resting stage over cold periods. In the spring, the shell softens and a new hydra will emerge. Hydra oligactis-Brown Hydra.
Detailed explanation-2: -Hydra may sexually produce eggs or have offspring that bud off asexually from the parent, but asexual budding occurs more frequently than sexual reproduction. Simultaneous or sequential hermaphroditism (both sexes present at some time) is the rule in hydra.
Detailed explanation-3: -Hydra reproduces asexually by budding.
Detailed explanation-4: -Following unfavorable conditions, such as injuries or periods of scarce resources, hydras occasionally reproduce through transverse and longitudinal fission.
Detailed explanation-5: -Hydra can survive near freezing temperatures.
