Peninsula Cooter

Fascinating facts about the Peninsula Cooter

• Most peninsula cooters stay between 9-13 inches (23–33 cm) long and weigh 5-15 lb (2.27–6.8 kg), yet the biggest individuals can top 16 inches (40.64 cm) and tip the scales at 35 lb (15.876 kg), showing the species can dwarf its average size under the right conditions.
• Unlike the Florida red-bellied cooter, the peninsula cooter’s shell and limbs are splashed with dozens of bright yellow stripes, while its belly stays a plain hue, making the pattern a quick field ID for herpetologists.
• Male peninsula cooters are smaller and have greatly elongated front claws used to stimulate the female prior to mating.
• You’ll find this turtle across peninsular Florida in everything from slow-moving ponds to faster rivers and even lake shorelines, proving it can thrive in a wide range of freshwater habitats.
