7. Ball Python (Python regius)
Ball pythons are indigenous to West and Central Africa. In the wild, they typically inhabit savannas and grasslands.
These snakes are named for the way they behave when they feel threatened. Instead of slithering away or striking out, they curl into a tight ball to appear smaller.

9. Yellow-Bellied Slider (Trachemys scripta scripta)
Yellow-bellied sliders are basking turtles that are found in abundance in the southeast United States and are popular as pets. They are semi-aquatic, spending much of their time floating in the water and coming out on land to bask.
At maturity, the shells of these turtles reach 5-12 inches in length. Juveniles eat primarily aquatic insects, while adults mainly eat vegetation.
10. Red-Eared Slider (Trachemys scripta elegans)
Red-eared sliders are very much the same as yellow-bellied sliders in size, behavior and needs. They are native to the Mississippi river but have been seen in many other states and some parts of Canada.
Red-eared sliders kept as pets are often released into the wild, which explains their presence in locations other than the Mississippi. Many released sliders do very well in the wild, and they are considered an invasive species in some areas.
11. African Sideneck Turtle (Pelomedusa subrufa)
Also known as the African mud turtle, the African sideneck turtle gets its name from its lack of ability to tuck its head all the way into its shell. Instead, it draws its head sideways under the upper edge of the shell.
The average adult African sideneck’s size falls between 7 to 12 inches, with females averaging a greater size than males. They are known for their longevity, with some reports suggesting they can live more than 50 years in captivity.
12. Western Painted Turtle (Chrysemys picta bellii)
The painted turtle is a freshwater species prevalent in North America, typically residing in ponds, slow-moving rivers and creeks, and murky bogs. They need a habitat with fresh water, a soft bottom, basking sites, and aquatic plants.
Mature female turtles reach 12 inches in shell length. Males are smaller with an average shell length of 10 inches.
