Turtles are ready to mate when their carapace measures about 8 inches. The nesting season is from April through November, with most of the nesting in southern New England occurring in late May through June. Snapping turtles rarely leave their aquatic habitat except during the breeding season, at which time females travel great distances in search of a place to dig a nest and lay eggs.
Some turtles have been found as far as a mile from the nearest water source. Selected nest sites include banks, lawns, gardens, road embankments, and sometimes muskrat burrows. One clutch of eggs is laid in May or June.
With powerful hind legs, the female digs a shallow bowl-shaped nest in a well-drained, sunny location.
Over a period of several hours, she lays approximately 20 to 40 creamy white, ping-pong ball-sized eggs. After covering the eggs, the female returns to the water, leaving the eggs and hatchlings to fend for themselves.
Turtle nests are often preyed upon by raccoons, skunks, and crows. Snapping turtles have temperature-dependent sex determination. Hatching takes approximately 80 to 90 days, but the hatch date can vary depending on temperature and other environmental conditions.
Generally, hatchlings emerge from their leathery egg in August through October by using a small egg tooth to break open the shell. When the young hatch, they dig out of the nest and instinctively head to water. Young at hatching are about an inch long with soft shells and they must make it to water without being preyed upon by raccoons, skunks, foxes, dogs, birds, and snakes.
When they reach water, the young turtles may be taken by fish and other snapping turtles. Once the turtles have grown some and their shells harden, they are virtually predator-free.

Snapping Turtles prefer to burrow down and lay on the bottom of their enclosure between surface visits as an ambush behavior.
Removing their ability to have anywhere to hide can stop this behavior entirely. They are much calmer and more likely to avoid you in the water, but once removed, they can become overly aggressive.

They have an extremely high cold tolerance and often remain active, even underneath sheets of ice.
They will bury themselves in the muddy bottom of a lake or river and expose their heads in the water. For up to six months, these turtles can remain buried, breathing only through membranous gas exchanges.
In captivity, many of these behaviors are retained. Females may root around their dry dock during laying season, but otherwise rarely leave the water. They have strong, sharp beaks and long necks, so special handling skills are needed for this species. The Snapping Turtle is known to be aggressive as adults, especiallyf when taken out of water.

Females also tend to be smaller, but this is not always a reliable way to sex them. Hatchlings tend to be similarly sized regardless of sex. They can be 2. By 5 years old, most males have reached sexual maturity and should measure approximately 6 inches long.
By years growth slows , and your turtle will slowly reach their maximum size of between inches and pounds. Wild Snapping Turtles tend to have tan, brown, or black shells. However, this shell tends to get covered by mud and algae over time. Their skin is an olive-yellow color over most of their body, except their heads, which tend to be darker. Babies are typically defined as being less than 6 months in age and have very similar care requirements to adults.
The shell of a snapping turtle can be brown, tan or olive green. Young snapping turtles showcase light brown shells. The color of their skin varies and is frequently yellow, brown, rusty orange or slightly red. Factors believed to affect skin color include diet, water quality and soil type.
