Bimodal Reproduction

	Bimodal Reproduction Bimodal reproduction is the ability of a vertebrate animal to reproduce by both laying eggs and giving birth. Examples of these animals include Saiphos equalis and Zootoca vivipara, References {{reflist Reproduction in animals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Saiphos Equalis ''Saiphos equalis'', commonly known as the yellow-bellied three-toed skink or simply three-toed skink, is a species of burrowing skink found in eastern Australia. It is the only species classified under the genus ''Saiphos''. The lizard has attracted scientific attention due to its dual reproduction habits of producing young via eggs in coastal populations, or via live young in colder mountain regions.Marshall,M., Live birth, evolving before our eyes, ''New Scientist'', 25 August 2010/ref> Description ''Saiphos equalis'' grows to a length of including the tail. It has a brown back and an orange belly. The skink is active at night, and feeds on insects. Along the coastal lowlands of Australia, the skink has been observed laying eggs and giving birth to live young for reproduction. Individuals of the species in the lowlands lay eggs (oviparous), while its neighbors to the north in the mountains are almost exclusively giving birth to live young (viviparous).

picture info	Zootoca Vivipara The viviparous lizard, or common lizard, (''Zootoca vivipara'', formerly ''Lacerta vivipara''), is a Eurasian lizard. It lives farther north than any other species of non-marine reptile, and is named for the fact that it is viviparous, meaning it not only lays eggs, but also gives birth to live young. Both "''Zootoca''" and "''vivipara''" mean "live birth," in Greek and Latin respectively. It was called ''Lacerta vivipara'' until the genus ''Lacerta'' was split into nine genera in 2007 by Arnold, Arribas & Carranza. Male and female ''Zootoca vivipara'' are equally likely to contract blood parasites. Additionally, larger males have been shown to reproduce more times in a given reproductive season than smaller ones. The lizard is also unique as it is exclusively carnivorous, eating only flies, spiders, and insects. Studies show that the more carnivorous an individual is (the more insects they eat), the less diverse the population of parasitic helminths that infest the lizards. ''Z ...
