Comparing a male and a female snapping turtle
The 5 main differences between a Male and Female Snapping Turtle
The main differences between male and female snapping turtles are that males are larger, have longer tails, and have a curved plastron (bottom shell). Snapping turtles are some of the most common and fearsome turtles across the eastern United States. Heavily armored and stealthy, these reptiles are famous for being able to “bite a finger off” if given a chance. Thankfully, they don’t really like being around humans and swim off before we ever get close. Although they have a bad reputation, snapping turtles have been around for a long time and play an important role in water ecosystems. The common snapping turtle is the most common member of the Chelydra genus and the one that most people are familiar with. Although it isn’t easy to tell right away, there are some distinct differences between the various species and even between the sexes. Today, we are going to explore the differences between male and female snapping turtles.
Male vs Female Snapping Turtle: Size
In many species, there is a size discrepancy between males and females. In the case of snapping turtles, males are generally larger. On average, male turtles grow between 10 and 35 lbs, although they technically have no upper limit. The majority of turtles more than 22 lbs are old males. Female turtles are usually smaller than males. On average, a female turtle weighs between 10 and 20 lbs but could theoretically get larger than that.
Male vs Female Snapping Turtle: Tails
The easiest way to tell the difference between a male and a female snapper is their tails. In males, the tail is longer and thicker than the females. For most people identifying by eye, this is the best method when sexing them. Female turtles generally have shorter, thinner tails when compared to males.
Male vs Female Snapping Turtle: Plastron
The plastron is the section of the shell under the body of a turtle. In snapping turtles, plastrons are remarkably small when compared to most turtles around the world. Additionally, they appear disconnected. Still, looking at the plastron of a snapper can give clues as to its sex. Males are generally recognized as having a plastron that is slightly curved. Females usually have a plastron that is flatter than males. Although this detail is useful, it’s not as practical for the average person to check as they would have to risk a serious bite to flip the turtle over.
Male vs Female Snapping Turtle: Reproduction
One of the primary differences between male and female turtles is their reproduction habits. Turtles practice iteroparity (repeated reproductive events) over the course of their life and sexually mature between 12-20 years. Males contribute sperm to the life equation, but that’s about it. They don’t care for or protect the eggs or hatchlings in any real way. Females, on the other hand, play a much larger role. After mating with a male, a female can hold onto his sperm for several seasons, using it to create viable eggs whenever she deems it necessary. When she is ready to lay, a female turtle will travel over land in order to find sand soil to dig. Per year, females usually lay between 25 and 80 eggs total.
Male vs Female Snapping Turtle: Land travel
Although both males and females can travel on land, males are usually less likely to be found away from the water. The only reason males will leave the safety of the water is if they are hoping to branch out and find more territory to inhabit. Females are much more likely to be found away from water. In fact, while looking for a place to lay eggs, female snappers are known to travel a considerable distance to find sand.
