The alligator snapping turtle (Macrochelys temminckii) is a large, highly aquatic freshwater turtle of the southeastern United States. It spends much of its time resting on river or lake bottoms, where its rough shell and algae-friendly skin can help it blend into submerged wood and leaf litter. It is not a marine turtle and does not hunt on land.
A small lure inside a powerful ambush
When an alligator snapping turtle ambushes prey, it may lie still with its jaws open and wriggle a small, worm-like fleshy appendage on its tongue. Fish and other animals may investigate the movement, bringing them within reach. This is a tongue lure, not a blood-filled organ, and it is only one part of the turtle’s feeding behavior.
Life in freshwater habitats
Adults use deep rivers, oxbows, lakes, swamps and other slow-moving freshwater habitats. Their diet is varied and can include fish, aquatic invertebrates, carrion and other available prey. Young turtles may use the tongue lure more often than adults, but diet and hunting behavior change with age, habitat and opportunity.
Why the species needs protection
Harvest and poaching, fishing gear, habitat alteration and nest predation can all affect populations. Conservation work is most useful when it protects habitat, monitors populations, reduces avoidable bycatch and supports licensed head-start or release programs. Never remove a wild turtle from its habitat or approach one closely enough to risk a bite.
Observe without interfering
A resting turtle can be difficult to spot, which is part of its survival strategy. Give wildlife space, keep pets away from nesting areas and report injured animals to the appropriate local wildlife authority. Accurate sightings from a distance can be useful to researchers, but handling should be left to permitted professionals.
