Diagram comparing reproductive pathways: arrows show sexual reproduction forming a diploid zygote from oocyte and sperm, haploid parthenogenesis forming a haploid individual, and two types of diploid parthenogenesis-automixis and apomixis-both resulting in diploid individuals. Symbols indicate haploid and diploid stages. — Animal reproductive system The process of sexual reproduction and several forms of parthenogenesis.

Hydra typically reproduce asexually through a process known as budding. During this process, small portions of the adult structure develop into new, genetically identical individuals.123

Specifically, finger-shaped outpushings of the Hydra's body wall form and begin to develop their own mouths and tentacles. Once these structures are sufficiently developed, the new individual nips off at the base, separating from the parent to become an independent organism. This method allows the Hydra to increase its population without the need for fertilization.123
