In early spring the females nest on land, along the banks of small ponds. After the 4–6 week embryonic period, the larvae hatch and make their way to the adjacent pond. Four-toed salamanders undergo a relatively short aquatic larval period, when compared to other species of the same family, ranging between 3 and 6 weeks. [3] [4] [6]
Blanding's turtle, an endangered species found in Nebraska. Thirteen species of amphibians and forty-seven species of reptiles are native to the U.S. state of Nebraska. [1] [2] This list only includes native species.

A large number of very well preserved fossil Teleoceras (extinct hippo-like relatives of rhinos), small three-toed and one-toed horses, camels, and birds have been excavated. Many animals were preserved with their bones articulated; one rhino still bears her unborn fetus , while others retain the contents of their last meal.
Biofluorescence in a three-toed amphiuma. The three-toed amphiuma looks rather eel-like, with an elongate, dark gray-black, or brown colored body, and tiny vestigial legs. A large salamander, one record sized individual was recorded at 41.25 inches (104.8 cm), but 18–30 inches (46–76 cm) is the typical size of an average adult. [3]
Rhinoceroses first appeared in Nebraska during the Eocene epoch. They would continue to thrive on the plains for the next 35 million years. In fact, more Tertiary-aged rhinoceros remains have been found in Nebraska than any other state. [1]: 189 Rhinoceroses remained and were a prominent member of Oligocene Nebraska's fauna. Camels were a new ...
The long-toed salamander (Ambystoma macrodactylum, Baird 1849) [4] is a mole salamander in the family Ambystomatidae.This species, typically 4.1–8.9 cm (1 + 3 ⁄ 5 – 3 + 1 ⁄ 2 in) long when mature, is characterized by its mottled black, brown and yellow pigmentation, and its long outer fourth toe on the hind limbs.
Plethodontidae, or lungless salamanders, are a family of salamanders. [ 1 ] [ 2 ] With over 500 species, lungless salamanders are by far the largest family of salamanders in terms of their diversity. Most species are native to the Western Hemisphere , from British Columbia to Brazil.
