Turtle

Turtles are reptiles of the order Testudines that visitors can see on a Everglades airboat tour, known for their special bony or cartilaginous shell, which extends from their ribs and acts as a shield. The earliest known members of the group date back to 157 million years ago, making them one of the oldest reptile groups – older than snakes and crocodilians. Turtles are ectotherms, meaning that their internal temperature varies according to their environment.

Turtle Habitat

Turtles are found above and below ground, perfect for trying to spot during our world-famous Everglades airboat tours. They can be found in all warm and temperate waters throughout the world and some migrate hundreds of miles between nesting and feeding grounds.

Turtle Size & Appearance

Known species you will see at Everglades Holiday park span in length from 3 inches to 6.6 feet and range in weights between 5 ounces to a full ton – 2,000 pounds! Turtles are separated into two groups depending on how they withdraw their necks into their shells. The Cryptodira withdraw their necks under their spines, while the Pleurodia contract their necks to the side; spotting these differences on a group airboat tour or a private airboat tour is always a great game to play. They have rigid beaks and use their jaws to cut and chew food. The jaws are covered in sharp, horny ridges rather than teeth. Their upper shell is called the carapace while the lower shell is called the plastron. They are joined together on turtles’ sides by bony structures called bridges.

Diet

Their diets are largely dependent on the species and the habitat in which they are found. While on a Everglades excursion for food, turtles typically diet on many plants that grow in water, small insects, snails, worms and even dead marine animals and fish. Due to the importance of protein intake in their growth, the wild variety are mainly carnivorous when they are young and gradually add plants and vegetation to their diets as they age.
