The Pacific newts (Taricha) and the Eastern newts (Notophthalmus) with together seven species are the only representatives in North America, while most diversity is found in the Old World: In Europe and the Middle East, the group's likely origin, eight genera with roughly 30 species are found, with the ribbed newts (Pleurodeles) extending to ...

“She’s literally, like, still laying.”
Before the eggs are deposited, male mudpuppies leave the nest. [6] Once ready, the female deposits the eggs in a safe location, usually on the underside of a rock or log. [7] They can lay from 20 to 200 eggs, [4] usually an average of 60. [6] The eggs are not pigmented and are about 5–6 mm (0.20–0.24 in) mm in diameter.
Notophthalmus species are East American newts similar in shape to the European newts (cf. Triturus). As a distinct characteristic of their own, both sexes have three to four large pores that lie in a row on the temple. The skin is smooth and soft in the water form and the tail is strongly flattened laterally.
