Spotted turtle

The spotted turtle is a petite reptile that splits its time between water and land. Its glossy black shell is dotted with bright yellow polka-dots that stretch across its skin. You can tell males apart by their darker faces and tails nearly twice as long as the females'.

• Adults grow no larger than a grapefruit, with shells measuring 3-5 inches across.
• Males develop ink-black eyes while females keep golden-colored ones.
• Their yellow spots act like fingerprints—no two turtles share the same pattern.
