Pseudemys concinna suwanniensis

Pseudemys concinna suwanniensis

Also known as Suwannee River Cooter

Suwannee cooters spend clear Florida mornings basking on sun-drenched river logs, absorbing heat before diving to graze on submerged river meadows. As specialized river herbivores, adults use finely serrated jaw cusps to crop tough aquatic plants like eelgrass and spring run vegetation. Adult females make annual treks onto sandy river terraces to nest, requiring quiet, intact riverbanks to lay their eggs safely.

Responsible observation
