Are you curious about the age of snapping turtle by size? Well, you’ve come to the right place. In this article, we’ll give you a detailed guide on how to determine age based on size for hatchling, juvenile and adult snapping turtles.
Male common snappers reach maturity at age 4 to 6 years, with a carapace length of 7.08 – 7.48 inches (18 to 19 cm), while females take a little longer, reaching maturity between 10 to 12 years of age. By this time, the female will have a carapace length of 7.87 to 8.66 inches (20 to 22 cm).
Close your eyes, and follow the traditional ways of finding out snapping turtle’s age, for example, by size calculation. Snapping turtles show a narrow range of size distribution at a particular age. Compare your snapping turtle’s current growth with the standard size-age distribution chart.
The common snapping turtle (Chelydra serpentina) is a species of large freshwater turtle in the family Chelydridae. Its natural range extends from southeastern Canada, southwest to the edge of the Rocky Mountains, as far east as Nova Scotia and Florida.
Snapping Turtle Size and Appearance. Snapping turtles are among the most prehistoric-looking reptiles in existence. Like dinosaurs, they’re huge and covered in tough, armor-like skin and scales. You may wonder: Just how huge? Chelydra spp.: Carapace (top shell): 9.8 – 20 in. (24.9 – 50.8 cm) Weight: 9.9 – 35.3 lbs. (4.5 – 16 kg)
Snapping turtles reach adulthood between 8 and 10 years old and can live for decades beyond that. The carapace measures 8-12 inches on an average adult, and fully-grown turtles can weigh between 10 to 35 pounds. Takedown request View complete answer on portal.ct.gov.
Adult snapping turtles, on the other hand, can grow up to 18 inches in length and weigh more than 35 pounds. By measuring the size and weight of a snapping turtle, you can determine its age. To accurately measure the size and weight of a snapping turtle, use a digital scale and a measuring tape.
Method 1: Counting Rings. This involves counting the growth rings on the turtle’s shell and dividing that number by two. An example given is if there are 14 rings, the turtle’s age is estimated to be 7 years. Method 2: Checking The Size. A chart compares the plastron length (the bottom part of the shell) of males and females to the turtle’s age.
Alligator snapping turtles can grow to some 80 to 100 cm (31.5 to 39.3 inches) and weigh about 70 to 90 kg (about 154.3 to 198.4 pounds). Their life span in the wild ranges up to about 45 years, although they can live much longer in captivity. The oldest alligator snapping turtle ever recorded was a captive that reached 70 years old.
Common Snapping Turtle Size and Lifespan On average most common snapping turtles live between 35 and 40 years, and reach sizes between 8 and 15 inches. In general, females tend to be slightly bigger than males.
