Predators Northern short-tailed shrews, Striped skunks, Virginia opossums, raccoons, foxes, and the North American River Otter. Most predation is on eggs, and juveniles. Habitat Blanding s turtles are semi-aquatic, living mostly in shallow wetland habitats where aquatic vegetation is abundant. Region Native to Canada, stretching as far west as southeastern Ontario and as far east as southern Nova Scotia. They continue southward to the United States. With a range including the Great Lakes region, this reptiles range stretches as far northeast as Maine and as far northwest as South Dakota and Nebraska, including southeastern New York, Pennsylvania, Illinois, Indiana, Iowa, Massachusetts, southern Michigan, southeastern Minnesota, New Hampshire, as well as Ohio.

Blanding s Turtle Emydoidea blandingii 3 Reproduction Polyandrous: females mate with several males during on breeding season. The females reach sexual maturity at 14 to 21 years, averaging maturity at 18 years. Males tend to reach sexual maturity at around 12 years. The females have all of the control in the courtship process when it comes to choosing their mates. However, during courtship, the males are very aggressive and are the ones who seem to be in control, mounting the females and grabbing their carapaces. The females tend to mate with the same males each year. Mating takes place year round, but mostly the start of spring in March and early April. o Mating takes place at night. Females will only nest and lay eggs once a year, between the last weeks of June and the beginning of July. Clutches are products of more than one father, and may be cared for by multiple male turtles, usually two, but occasionally up to three mates. Clutch sizes range from 3 to 19, averaging around 10 eggs. The incubation period typically lasts between 80 and 128 days. Females leave the eggs once they bury them in a safe nesting spot, and the males watch over the eggs from then on until the final days of the incubation period. Behavior Blanding s turtles are mostly aquatic, they commonly emerge from the water to rest on logs, sedge clumps, or any terrestrial land that is close to their aquatic homes. Overwinter in both terrestrial and aquatic habitats. On land males will travel, on average, over 6 miles in a day. Adaptations The hinges of the ventral shell are able to move.

Common Snapping Turtle Chelydra serpentina 6 John Ball Zoo Habitat Located in the North America Turtle habitat (Weather permitting). Individual Animals: 1 Male Birth date and location unknown Arrived October 07, 2012 o From a Private Donor Life Expectancy Wild: up to 30 years Under Managed Care: 47 years Statistics Largest species of turtle native to Michigan Length Carapace: 8-18.5 inches o Tail is almost as long as the shell Weight 8.8-35 pounds Diet Omnivore Wild carrion, invertebrates, fish, birds, small mammals, amphibians, and a surprisingly large amount of aquatic vegetation. Predators None once they are full grown. The eggs and hatchlings of snapping turtles may be eaten by other large turtles, great blue herons, crows, raccoons, skunks, foxes, bullfrogs, water snakes, and large predatory fish, such as largemouth bass. Habitat Fresh or brackish water. They prefer water bodies with muddy bottoms and abundant vegetation because concealment is easier. Region From S. Alberta and east to Nova Scotia in the north, extending south all the way to the Gulf of Mexico and into central Texas. Reproduction Over most of its range, the common snapping turtle mates from late March to November. Over much of North America, the main nesting period of this species is between mid- May and mid-june. Using its hind feet, the female common snapping turtle digs a flask-shaped nest, usually in relatively loose sand, vegetable debris. In most populations of the common snapping turtle, only one clutch is laid per breeding season. The eggs are roughly the size of a ping-pong ball.

Common Snapping Turtle Chelydra serpentina 7 A clutch consists of between 25 and 45 eggs. Incubation last 75-95 days. Adaptations The tail has saw-toothed keels on it. Behavior Diurnal This species is seldom seen basking, but can often be seen floating just below the water s surface. Adults sit and wait for prey to swim near it instead of actively seeking it out. Most common snapping turtles enter hibernation by late October. Hibernation usually ends around April, but this varies depending on the location.

Eastern Box Turtle Terrapene carolina carolina 8 John Ball Zoo Habitat Located in the Natural Treasures building. One can also be found in the Red Barn. Individual Animals: 3 Males Male Ted (darker coloration) o Born February 1995 (Estimate) Location unknown o Arrived February 19, 2015 Male Bill (lighter coloration) o Birth date and location unknown o Arrived March 08, 2008 Male Carl (split beak) o Housed in Upper Red Barn o Birth date and location unknown o Arrived 1985 Life Expectancy Can live over 100 years. Statistics Length 4.3-7 inches, females tend to be smaller Diet Omnivore Wild snails, insects, berries, fungi, slugs, worms, roots, flowers, fish, frogs, salamanders, snakes, birds, and eggs. Predators Few species can prey effectively on adults due to their ability to close their shells. Habitat Forest, savanna, or grassland. Region Exclusively North America Ranging from southern Maine to Florida along the East Coast, and west to Michigan, Illinois, eastern Kansas, Oklahoma, and Texas. Reproduction Polygynandrous both males and females can have multiple mates. Sexual maturity is reached around 5 years of age. Mating season begins in the spring and continues throughout summer until October. Males sometimes fall backwards after copulation, and if they can't right themselves they die of starvation. Nesting occurs from May through July. Nests are usually dug in sandy or loamy soil, using the hind legs. Then eggs are laid in this cavity and the nest is carefully covered up again.

Eastern Box Turtle Terrapene carolina carolina 9 A female may lay fertile eggs for up to four years after one successful mating. There are 3-8 eggs laid, though usually 4 or 5, and they are elliptical with thin, white, flexible shells. Incubation last roughly 3 months Adaptations Hinged plastron (ventral part of shell) that allows box turtles to close their shells almost completely. Male Box turtles eyes tend to be more colorful than females. The red or orange coloration may help females to identify males from a distance. Behavior Diurnal When it gets too hot, they hide under decaying logs and leaves, crawl into mammal burrows, or in mud. When it is very hot, they go into shady pools and puddles to cool off. In the northern regions they go into hibernation in October or November and emerge from hibernation in April. o Further south, they remain active later in the year. To hibernate, they burrow as much as two feet deep into loose earth, mud, stream bottoms, old stump holes, or mammal burrows. Eastern Box Turtles are the only land turtle native to Michigan. Conservation Concerns Degradation, fragmentation and destruction of Box Turtle habitat is widespread Numbers are also declining due to the pet trade. While listed as vulnerable, their population is decreasing and they are a species of concern in many states.

Painted Turtle Chrysemys picta 10 John Ball Zoo Habitat There are 3 Painted turtles located in the North America Turtle Habitat. Individual Animals: 2 Males, 1 Female Male o Hatch location and date: Unknown o Arrived July 10, 2008 From public donor Male o Wild Hatch (Michigan) Date: Unknown o Arrived April 26, 2008 Female o Hatch location and date: Unknown o Arrived March 10, 2008 From public donor Life Expectancy Painted turtles may live as long as 35 to 40 years. Statistics Length 3.5-9.8 inches Weight 13 ounces Diet Omnivore Wild plants, small animals, such as fish, crustaceans, aquatic insects, and some carrion. Predators Mink, raccoons, foxes, North American River Otters, and other medium-sized predators. Habitat Painted turtles prefer living in freshwater that is quiet, shallow, and has a thick layer of mud. Region Painted turtles are one of the most common turtles in North America and are found from southern Canada to northern Mexico. The Painted Turtle is Michigan s state reptile.

Painted Turtle Chrysemys picta 11 Reproduction Polygynous: having more than one female as a mate at one time. Mating begins after hibernation and before feeding begins when the water temperatures are still low. The breeding season lasts from late spring to early summer. Males mature at about 3-5 years of age. Females take longer at 6-10 years. In the early summer females lay 4 to 15 oval, softshelled eggs, in a flask-shaped hole. Females choose soft, sandy soil with good exposure to the sun in which to dig the hole. Once the eggs are laid they cover the hole and leave. The young hatch and dig out of the nest on their own, they are independent immediately. Behavior Diurnal Painted turtles must eat in the water, their tongue does not move freely and they cannot manipulate food well on land. Painted turtles bask in large groups on logs, fallen trees, and other objects. The sunning helps rid them of parasitic leeches. In many areas turtles hibernate during the winter months by burrowing into the mud and allowing their bodies to become very cold. They use touch to communicate with each other, particularly during mating. Adaptations They have no teeth, the turtle jaw has tough plates for gripping food. Sound perception is poor in turtles, but they do have a good sense of smell and color vision.

Spotted Turtle Clemmys guttata 14 John Ball Zoo Habitat There is 1 spotted turtle located in the Frogs and friends building. Individual Animals: 1 Male, 3 Undetermined Male o Housed in Frogs and Friends o Hatched September 2010 Unknown location o Arrived February 24, 2011 Private Donor Life Expectancy Can reach over 100 years of age. Statistics Smallest species of turtle native to Michigan Length 4.5 inches Diet Omnivore Wild algae, leaves of soft aquatic plants, water lily seeds, worms, mollusks, crustaceans, adult and larval insects, amphibian eggs and larvae, and carrion. Predators Raccoons, Common Snapping Turtles, Muskrats and Foxes. Most predation is on eggs, and juveniles. Habitat Shallow waters with a soft bottom substrate and some submergent and emergent vegetation. Sedge meadows, boggy ponds, fens, tamarack swamps, and slow, muddy streams. Region Eastern North America: from Canada to Northern Florida including the Midwest. Within this range, the Spotted Turtle is spottily distributed in the remaining suitable habitat, and most populations are small and colonial in nature. Behavior Spotted Turtles tend to become inactive in the warmest part of the summer. When surprised while basking, Spotted Turtles will dive into the water and bury themselves in the bottom mud.

Reproduction Sexual maturity at a carapace length of 3.5 inches (around 7-14 years of age). Male Spotted Turtles may fight each other, presumably over access to females. Courtship involves the male chasing the female under water while nipping and biting her legs and carapace; he then mounts her shell and bites at her head and neck. Copulation occurs in shallow water and may last for an hour. Nesting can occur from late May through June. Females typically lay only one clutch of from 1 to 8 eggs per year, though a few may lay a second, smaller clutch a few days after the first. Nesting females seek open, sunny locations that offer moist, but well-drained, soils. The sex of the hatchlings is determined by nest temperature during the middle third of the incubation period; cooler experimental temperatures produced mostly males, and warmer temperatures produced only females.

Wood Turtle Glyptemys insculpta 16 John Ball Zoo Habitat Located in the North America Turtle habitat (Weather permitting). One can also be found in the Red Barn. Individual Animals: 2 Females Female Harding o Housed in Upper Red Barn o Hatched between April and August 2003 Location unknown o Arrived February 19,2005 Public Donor Female o Housed in the North America Turtle Habitat o Hatched between April and August 2003 Location unknown o Arrived February 19,2005 Public Donor Life Expectancy Wood Turtle can reach 60 years of age. Statistics Carapace Length 6.3-9.8 inches Diet Omnivore Wild leaves, flowers, berries, fungi, slugs, snails, worms, and insects. o Opportunistically consume young mice or eggs, or scavenge dead animals. Predators Few species can prey effectively on adults. Raccoons prey upon nests. Habitat Forest, rivers, and streams Region Small area of eastern Canada and the northeastern U.S. Reproduction Wood turtles in the wild usually reach sexual maturity between 14 and 20 years of age. Courtship may include a mating "dance" in which the male and female face each other and swing their heads back and forth; perhaps more frequently the male simply pursues the female while nipping at her limbs and shell and then mounts her carapace. Mating is most frequent in spring and fall. The female excavates the nest with her hind feet, creating a globular cavity about 2-5 inches deep.

Wood Turtle Glyptemys insculpta 17 Clutch size ranges from 3 to 18 eggs (usually 5 to 13). Only one clutch is produced each year, and females may not reproduce every year. Incubation requires from 47 to 69 days. Hatchlings generally emerge from their nests in late August or September and move to water. Adaptations The scutes, or scales, on the wood turtles shell show concentric annual growth that can be used to approximate the turtle age. Behavior Diurnal They can capture earthworms by thumping the ground with their forefeet or the front of the plastron. It is thought that the worms may mistake the vibrations caused by this thumping for the approach of a mole or perhaps a hard rain, and come to the surface, only to be grabbed by the hungry turtle Conservation Concerns Habitat degradation, fragmentation and destruction are widespread in Wood Turtles' areas of occupancy, from residential and recreational developments. Predation by raccoons is significant, and believed to result in no recruitment in Michigan.
