do rattlesnakes lay eggs or give birth to live young?
give birth to live young
"the reproductive behaviour of fishes is remarkably diversified: they may be oviparous (lay eggs), ovoviparous (retain the eggs in the body until they hatch), or viviparous (have a direct tissue connection with the developing embryos and give birth to live young). all cartilaginous fishes—the elasmobranches (e.g., sharks, rays, and skates)—employ internal fertilization and usually lay large, heavy-shelled eggs or give birth to live young. the most characteristic features of the more primitive bony fishes is the assemblage of polyandrous (many males) breeding aggregations in open water and the absence of parental care..."

"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).
