This chapter addresses turtles, starting with snapping turtles. In the United States, the common snapping turtle is exotic to Arizona, California, Nevada, New Mexico, Oregon, Utah, and Washington. A potentially abundant source of food for human consumption, this species has been transported outside its native range.

Diversity in the Matrix Structure of Eggshells in the Testudines (Reptilia)
Zoological Science, 2013The eggshells of 56 chelonians were examined by electron microscopy and X-ray diffractometry. They were classified into six types in terms of the matrix structure of their calcareous layer; type I was composed of a thin calcareous layer with minerals in an amorphous structure; type II with shell units composed of mammillary cores calcified with ...

American Midland Naturalist, 1964The greatly reduced plastron bones of highly specialized turtles are similar to those of hatchling turtles because mechanical requirements determine the final shape and position of the reduced bones. The turtle's plastron has three functions, only one of which is ventral armor.

As a result of the observations during 1963???19&7 it was established that Hoplocam-' pa testudineae Klug, under conditions of the Crimean foothill had a two- and three-year diapause. Not less than 15% of the larvae in cocoons remain annually in a state of the two-year diapause, and from 3.7 to 5.2% in a state of the three-year diapause.

Hipovitaminose A em Testudines
Os Testudines possuem uma dieta bastante variada e, em cativeiro, esses animais são comumente afetados por um desbalanceamento nutricional, fazendo com que surjam diversas enfermidades. Um dos distúrbios mais frequentes encontrados é a hipovitaminose A, já que alguns répteis não absorvem de forma adequada o betacaroteno, sendo necessário a reposição naLB Silva +5 more
