How are many rattlesnakes born regarding their development inside the mother?

Answer

Ovoviviparous.

Many rattlesnake species exhibit ovoviviparity. This developmental strategy means that the eggs, while still containing specialized membranes for protection, are retained inside the mother's body until the young are fully developed. They are subsequently born live as miniature replicas of the adults. This contrasts sharply with amphibians, which usually lay gelatinous eggs in water, and is a key reproductive adaptation defining many advanced reptiles.
