Reptile reproduction -
Most reptiles lay eggs. The act of laying eggs is called oviposition. Reptiles that lay eggs are called
oviparous.
Some reptiles bear live young, and the term for this is
viviparous.
Technically, a female that lays eggs is said to be
gravid when she is holding eggs inside of her. A female that gives birth to live young may correctly be called
pregnant.

Herp veterinarians are different from other veterinarians in that they specifically sought out additional training to learn far more about reptile and amphibian medicine than is covered in the usual veterinary school curriculum.

Amphibian Morphology and Reproduction
Skin
An amphibian's very thin skin isn't covered by fur, feathers, or scales. This makes them vulnerable to dessication and abrupt temperature change, but also offers several advantages. Amphibians can breath through the entire surface of their bodies. In the case of the lungless salamanders (Plethodontidae), gas exchange through the skin alone provides sufficient oxygen.
