Common snapping turtles are fascinating creatures that have been inhabiting freshwater habitats for millions of years. They are known for their prehistoric appearance, with a large head, powerful jaws, and a thick, muscular tail. Snapping turtles are found throughout North America, predominantly in rivers, ponds, and marshes.

One of the most common questions people have about snapping turtles is how big they can grow. Let’s explore their size and growth patterns in more detail.

Size and Weight

Common snapping turtles are one of the largest freshwater turtles in North America. On average, adult snapping turtles can reach a carapace length (shell length) of 8 to 20 inches (20 to 50 cm) and weigh between 10 to 35 pounds (4.5 to 16 kg). However, it’s worth noting that some individuals have been recorded to exceed these average sizes.

Males are generally larger than females, with their shells measuring around 12 to 18 inches (30 to 45 cm) in length. Females, on the other hand, typically have a carapace length of 8 to 12 inches (20 to 30 cm). Their size is influenced by various factors such as genetics, habitat quality, and diet.

Growth Rate

Snapping turtles grow relatively slowly compared to other turtle species. It can take them 10 to 20 years to reach their maximum size. Their growth rate is highly dependent on environmental conditions, food availability, and overall health. A healthy snapping turtle living in a favorable habitat with an abundance of food will have a better chance of attaining larger sizes.

During their first few years of life, snapping turtles show rapid growth. However, growth rate slows down significantly as they age. By the time they reach adulthood, their growth rate becomes much slower.

Life Span

Snapping turtles are known for their longevity. In the wild, they can live for several decades. The average lifespan of a snapping turtle is estimated to be around 30 to 40 years, although some individuals have been reported to live up to 100 years!

Several factors can affect the lifespan of snapping turtles, including predation, habitat quality, and human activities such as road traffic. However, if they manage to survive their early years, snapping turtles can live a long and fulfilling life in the wild.
