Eastern box turtles range in size from 4.5 to 8 in (11 to 20 cm) long. Eastern box turtle in Florida. Eastern box turtles have many uniquely identifying characteristics as part of the box turtle group. While the female's plastron is flat, it is concave in males so the male may fit over the back end of the female's carapace during mating.
The limbs of these turtles are adapted for swimming, with every member having some level of toe webbing. [1] Most species exhibit temperature-dependent sex determination, as is typical of turtles; however, one species (the wood turtle) is known to have genetic sex determination. [5]
Temperature-dependent sex determination (TSD) is a type of environmental sex determination in which the temperatures experienced during embryonic/larval development determine the sex of the offspring. [1] It is observed in reptiles and teleost fish, with some reports of it occurring in species of shrimp.
The ZW sex-determination system is a chromosomal system that determines the sex of offspring in birds, some fish and crustaceans such as the giant river prawn, some insects (including butterflies and moths), the schistosome family of flatworms, and some reptiles, e.g. majority of snakes, lacertid lizards and monitors, including Komodo dragons.
The Eastern Box Turtle is the sole terrestrial one and the one we most often encounter, according to the a news release from the University of Tennessee Arboretum in Oak Ridge.
The XX/XY sex-determination system is the most familiar, as it is found in humans. The XX/XY system is found in most other mammals, as well as some insects. In this system, females have two of the same kind of sex chromosome (XX), while males have two distinct sex chromosomes (XY).
