Dasypeltis is a genus of snakes, also known commonly as egg-eating snakes or egg-eaters, in the subfamily Colubrinae of the family Colubridae. The genus is one of only two taxonomic groups of snakes known to have adapted to feed exclusively on eggs (the other being the genus Elachistodon ).
Nephila sp. eating a conspecific. Females exercise mate choice, rejecting unwanted and unfit males by cannibalizing them. [25] Mate choice often correlates size with fitness level; smaller males tend to display a low level of fitness; smaller males are therefore eaten more often because of their undesirable traits. [25]
Between about 1990 and 2011, foxsnakes were sometimes divided into two species, with P. vulpinus as the western foxsnake, and P. gloydi as the eastern foxsnake. A 2011 paper by Crother, White, Savage, Eckstut, Graham and Gardner proposed instead that the Mississippi River be established as the species boundary between two species of foxsnakes, and that those found to its east be considered P ...
The state also discourages residents from dumping water from household aquariums into waterways, as it can contain zebra mussel eggs. These tiny mussels reproduce rapidly and can clog drinking ...
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 ...
Parthenogenesis is a mode of asexual reproduction in which offspring are produced by females without the genetic contribution of a male. Among all the sexual vertebrates, the only examples of true parthenogenesis, in which all-female populations reproduce without the involvement of males, are found in squamate reptiles (snakes and lizards).

The juveniles hatch in the early fall. A newborn is 8–10 in (20–26 cm) in total length. Maturity is reached around 2 years old. Eastern racers have been known to lay their eggs in communal sites, where a number of snakes, even those from other species, all lay their eggs together.
Size dimorphisms are common in snakes; females tend to be larger in populations where the production of large liters is feasible. Males tend to be larger in mating systems in which male-male competition is a large factor. [33] Hydrophiid snakes, otherwise known as sea snakes, have only recently evolved from terrestrial elapids.
