We were looking for the spiny softshell turtle (Apalone spinifera), a native species, in the rivers around Las Vegas. Got some tips from a few local people on where we might find them and after 3 days of searching, we found this unusual turtle. Not sure we would find them as the temperatures had been near freezing which is often when turtles brumate (a type of hibernation for reptiles).
The turtle has an unusual tube-like protruding nose which makes it different from any other turtle we have photographed. It has a thin body and the shell (carapace) is somewhat flexible. Near the head, on the edge of the shell, there are some small spines and hence the name spiny softshell turtle.
We discovered them on some rocks on the far side of a fast-moving river. They were larger than we anticipated. The shell averages 40 cm (15 inches) but can be much larger, especially in females. Apparently, they can live for about 50 years.
At about 10 years of age, these turtles will begin to mate. This occurs mid to late spring as the temperatures warm. On average, the female deposits about 20 eggs on the sunny banks of the river generally in a sandy area or a gravel bed.
Like many turtles, they consume a wide variety of food. Insects and various types of vegetation make up a large portion of their diet as well as fish. They will often bury themselves in the river bottom and wait for a fish to pass by and then ambush their prey.
