  2. Hemipenis - Wikipedia

    en.wikipedia.org/wiki/Hemipenis

    A hemipenis (pl.: hemipenes) is one of a pair of intromittent organs of male squamates (snakes and lizards). [1] [2] [3] Hemipenes are usually held inverted within the body, and are everted for reproduction via erectile tissue, much like that in the human penis. They come in a variety of shapes, depending on species, with ornamentation such as ...

    en.wikipedia.org/wiki/Parthenogenesis_in_squamates

    Females can produce full clones of themselves through a modification of the normal meiosis process used to produce haploid egg cells for sexual reproduction. The female's germ cells undergo a process of premeiotic genome doubling, or endoreduplication, so that two consecutive division cycles in the process of meiosis result in a diploid, rather than haploid, genome.

    Some of the most highly developed sensory systems are found in the Crotalidae, or pit vipers—the rattlesnakes and their associates. Pit vipers have all the sense organs of other snakes, as well as additional aids. Pit refers to special infrared-sensitive receptors located on either side of the head, between the nostrils and the eyes. In fact ...

    en.wikipedia.org/wiki/Rattlesnake

    The female produces the ova ("eggs") in her ovaries, after which they pass through her body cavity and into one of her two oviducts. The ova are arranged in a continuous chain in a coiled section of the oviduct, known as the "tuba". [73] Male rattlesnakes have sexual organs known as hemipenes, located in the base of the tail. The hemipenis is ...

  6. Parthenogenesis - Wikipedia

    en.wikipedia.org/wiki/Parthenogenesis

    This type of reproduction has been induced artificially in animal species that naturally reproduce through sex, including fish, amphibians, and mice. Normal egg cells form in the process of meiosis and are haploid, with half as many chromosomes as their mother's body cells.

    Paddle-tailed sea snakes prey on fish eggs extracted from coral reef crevices. Some tree snakes have specialized jaws to extract snails from their shells, and use special chemicals to "de-slime" them.

  8. Red-sided garter snake - Wikipedia

    en.wikipedia.org/wiki/Thamnophis_sirtalis_parietalis

    The reproductive system of male snakes includes testicles, epididymis, vas deferens, hemipenes, and renal sex segment. [4] Testes produce sperm that are transported by epididymis to the vas deferens, which then transfer the sperm to hemipenes. These snakes have a double penis with one testis supplying seminal fluid to each hemipenis. [4]
