They typically lay 12 eggs in sand or other protected areas and leave the eggs to incubate unprotected. Clutches of five to 22 eggs have been observed. The eggs are elliptical, leathery, rough, sticky, and up to 70 mm (2 + 3 ⁄ 4 in) long. [17] The eggs typically hatch in August or September. Baby bull snakes are 20–46 cm (7.9–18.1 in) at ...
The hemipenis is the intromittent organ of Squamata, [4] which is the second largest order of vertebrates with over 9,000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate.

In all these cases, the young are born alive and fully functional. [20] The majority of caecilians are ovoviviparous and give birth to already developed offspring. When the young have finished their yolk sacs they feed on nutrients secreted by cells lining the oviduct and even the cells themselves which they eat with specialist scraping teeth. [21]

Since first appearing during the age of dinosaurs, snakes have authored an evolutionary success story - slithering into almost every habitat on Earth, from oceans to tree tops. Scientists ...
[133] [148] Workers laying trophic eggs have only been reported in two species; these species are M. forceps and M. gulosa. [149] Depending on the species, colonies specialise in trophallaxis; queens and larvae eat eggs that are laid by worker individuals, but the workers do not feed on eggs. [90]
Most birds do not have penises, but achieve internal fertilization via cloacal contact (or "cloaca kiss"). In these birds, males and females contact their cloacas together, typically briefly, and transfer sperm to the female. However, water fowls such as ducks and geese have penises and are able to use them for internal fertilization.
