Eggs
The eggs are arguably
the most vulnerable stage of a wood turtle's life. In some years,
skunks and raccoons can destroy up to 100% of clutches at a given nesting
site. One study noted that 15 of 17 nests were destroyed, but
that the nests were preyed upon 9 weeks after they were laid. Other
predators include coyotes and ravens. The larvae of certain flies
scavenge infertile eggs.
Hatchlings & Juveniles
Young
Wood Turtles are likely preyed upon by a wide variety of animals. Known
predators include raccoons, skunks, oppossums, chipmunks, dogs, cats,
several birds, and large-mouthed bass. Fly larvae can consume
live hatchlings in the nest chamber. These
fly larvae enter through the center of the plastron, where the turtle
was connected to its yolk sac.
Adults
Adult Wood Turtles are
often encountered with one or more missing limbs. In most cases,
limb mutilations and amputations are due to encounters with the wood
turtle's life-long enemy, the raccoon. In agricultural areas,
however, limb loss may be the result of agricultural mowers. After
15 years of investigation, one study documented a significantly lower
probability of recapturing Wood Turtles that had at least one missing
limb than those that were intact. So, it seems limb loss
can compromise the survival of certain turtles, at least over the long
term.
