This is Franklin, our Diamondback Terrapin. Diamondback Terrapins are a species of turtle that lives in brackish water here in Florida, which is different from our sea turtle residents who live in saltwater. Franklin was originally someone’s pet, but she decided to rehome him at CMA. He was named by our Terrific Turtles camp students and by our resident Russian tortoise.

The red drum uses its senses of sight and touch, and its downturned mouth, to locate forage on the bottom through vacuuming or biting. A 3-year-old red drum typically weighs 6 to 8 lb. The largest red drum on record weighed just over 94 lb and was caught in 1984 on Hatteras Island. They max at 5 ft in length.
