The Mud and Musk Turtles were long overlooked by reptile keepers, but many are now growing rapidly in popularity. Several make far better “first turtles” than Red Eared Sliders and other commonly-recommended species, as they are small (one species matures at 3-4 inches in length, and most average 6 inches), undemanding, and do not need UVB exposure. Although all have certain similarities, they exhibit a wide variety of fascinating lifestyles. Individuals of several species have reached 30, 40 and even 70+ years of age!
