Alligator snapping turtle care(Macroclemys temminckii)Description:Alligator snapping turtles are the largest freshwater turtles. They weigh between 155 and 175 pounds (70 to 80 kg). They are characterized by three large, pronounced ridges, or keels, that run from the front to the back of the carapace. With powerful jaws and a large head, they are unique among snapping turtles for having eyes on the side of the head. The alligator snapping turtle looks very primitive and has been called the dinosaur of the turtle world.
Alligator snapping turtles spend most of their time in the water, and generally only nesting females venture on land. However, males have been known to bask. They are solitary, and there is very little social structure or parental care. The turtles stay submerged for 40 to 50 minutes at a time, and only go to the surface for air. They are so motionless under water that algae may cover their backs and make the turtles almost invisible to fish.
Distribution and habitat:Alligator snapping turtles are native to the southeastern region of the United States. They are confined to the river systems that drain into the Gulf of Mexico.
They generally live in the deep water of large rivers, canals, lakes, and swamps. Hatchlings and juveniles usually live in small streams.
Adult size: 15 - 26"
Life span: They can live between 20 and 70 years in captivity.
Temperature Range (°F):Air temperature = Low to mid 80's
Basking temperature = High 80's to low 90's
Water temperature = 75 - 80°F
Diet: They are fed with mice, worms, fish, and prepared diet.
Beginner turtle?: NO!
Recommended enclosure:An outdoor pond above all else for adults, with 800 gallon stock tanks just behind. Juveniles (6-12 inches) are fine in smaller stock tanks and large (100+ gallon) aquariums.
Community habitat:Despite many large adults often being kept with other turtle species in zoo exhibits, alligator snapping turtles are best kept alone.
Status:There is no special status for the alligator snapping turtle. The main threat to the alligator snapping turtle is people who kill these reptiles for their meat.
Alligator snapping turtles play a role in freshwater ecosystems. Adults are not a source of food for any animals other than humans, but eggs and hatchlings are a source of food for large fish, raccoons, and birds. The adults, however, are important predators. Humans find them valuable for their unique appearance and their meat.
Reproduction:During reproduction, the male alligator snapping turtle mounts the back of the female. He grasps her shell with all four of his feet and inseminates her. It is unlikely that females reproduce more than once a year, and some females lay eggs in alternate years.
The turtles mate in early spring in Florida and late spring in the Mississippi Valley. They nest about two months later in a nest about 160 feet (50 m) from the shore. All nests are dug in the sand and clutch success is highly variable. A clutch may contain eight to 52 eggs and incubation takes 3.5 to 4.5 months. Hatchlings, therefore, emerge in the fall.
The sex of the hatchling is determined by incubation temperature and the hatchlings look very much like adults. Sexual maturity occurs in 11 to 13 years.
Other Information:Because of their extremely large size (heaviest freshwater turtle in the world), alligator snappers are not for beginners, or even experienced keepers if they cannot provide the space for these beasts.
