Life Cycle: 1.Mate shortly after winter 2.Most snakes lay eggs, some poisonous varieties lay live young 3.Eggs are soft and leathery 4.Clutches of eggs between 12-24. 5.Young are active and fend for themselves 6.Three years to achieve adulthood

12 Common Garter Snake

13 Non-Poisonous Range from 24 to 45 inches Usually three stripes down its back and typically greenish yellow Near water

22 Timber Rattlesnake

23 Endangered Species Adults average 38-43 inches in length. Poisonous

24 Frog and Toad’s Characteristics Habitat: frogs in wet areas or water covered, toads are terrestrial Feeding Habits: Tadpoles- vegetarians Adults- Carnivorous, eating insects Life Cycle: 1.Mostly begins as eggs, which hatches in short time 2.Tadpoles-aquatic creatures 3.Mating season is March until late summer 4.Females lay hundreds of eggs 5.Males attract themselves to receptive females 6.Females extrude her eggs and males fertilize them 7.Success depends on water temperature 8.Usually takes two year to become an adult 9.Hibernate during the winter

25 American Toad

26 Also known as the “Hop Toad” Adults are an olive-brown to reddish color with dark spots 2 to 4 inches in length Common in gardens and other cultivated areas

27 American Bullfrog

31 Tree Frog

32 Small Thinner Round pads on their toes Good climbers Aquatic and Terrestrial with some burrowers

33 Salamander

34 Salamanders Habitats: Moist, mostly terrestrial Feeding Habits: Strictly carnivours. Insects, eggs, larvae Life Cycle: 1.Fertilization is an internal process 2.Mating and egg-laying are not in the same season, sperm remains viable and females can carry it for months 3.Eggs may be laid on land or water 4.Eggs may be laid in masses, in strings or singly 5.Will hatch into tadpoles with gills 6.If laid on land will have vestiges of gills, with will shed 7.Time as larvae varies greatly from days to over a year 8.Develop at rates depending on temperatures and food 9.Live short lives
