Alligator Snapping Turtle
Macrochelys temminckii
alligator-snapping-turtle
Snapshot
North America’s largest freshwater turtle — males to roughly 31 inches carapace and very heavy — huge head, hooked beak, three carapace keels, worm-like tongue lure. In Georgia, the western M. temminckii occupies Gulf drainages outside the Suwannee basin (see Suwannee profile for M. suwanniensis). State-threatened complex; leave alone.

Description and identification
SREL: males to ~31 in / ~200 lb class — North America’s largest freshwater turtle. Very large head, strongly hooked beak, long tail. Dark brown carapace with three longitudinal keels; rear margin strongly serrated. Reduced plastron. Lacks the distinctly saw-toothed tail of common snappers. Pink worm-like tongue lure used in ambush. Males much larger than females.
Look-alikes
Common snapping turtle — smaller head, saw-toothed tail, statewide including ponds. Suwannee alligator snapping turtle (M. suwanniensis) — similar Macrochelys form but endemic to the Suwannee River watershed; treat as a separate ESA-listed species in south-central Georgia. Prefer drainage ID over casual shell cues.
Range in Georgia
Rivers and streams draining to the Gulf of Mexico — Mississippi system north to Iowa, east into southern Georgia and the Florida panhandle (SREL). Prefers riverine/oxbow settings, not isolated ponds. Georgia western / non-Suwannee Gulf drainages for temminckii; Suwannee basin = suwanniensis.
Habitat preferences
Rivers, streams, and oxbow lakes with woody structure; rarely isolated wetlands or farm ponds. Needs intact river corridors and nesting banks. Prefer Gulf-drainage riverine settings outside the Suwannee for temminckii.
Natural history
Extremely aquatic; rarely leaves water except to nest. Mate late winter–early spring; single clutch of about 10–60 eggs, ~90-day hatch. Ambush predator using the tongue lure; juveniles may lure more actively while adults may scavenge more. Slow maturity and low reproductive rate mean commercial harvest in the late 20th century still echoes in depleted populations.
Food preferences
Acorns, nuts, berries, vegetation, and animal prey — fish, turtles, snakes, salamanders, even small mammals or alligators opportunistically (SREL). Broad opportunistic river diet.
Temperament and encounters
Powerful jaws — never handle. State-threatened context: observe from shore or boat only; report violations to DNR.
Conservation and legal notes
SREL: populations depleted by commercial harvest mid–late 20th century; slow to recover. Considered Threatened in Georgia. Keep federal status language careful: the 2024 ESA Threatened listing applies to Suwannee M. suwanniensis — do not imply identical federal status for temminckii without checking the current rule. Species-split matters for compliance.
In Georgia, native turtles are wildlife. Many species are protected nongame animals; some are state- and/or federally listed. Possession, take, sale, and nesting-beach disturbance rules are species-specific — check current Georgia DNR and USFWS guidance before any collection or relocation. Do not invent statutes. Roads, habitat loss, bycatch, and illegal collection drive many declines. Educational observation from a distance is the default.
If you meet one
Leave listed turtles alone. Do not handle, collect, or casually relocate them. If one is in immediate danger on a road and you can act safely without injury to yourself or the animal, you may gently move it the short distance off the pavement in the direction it was traveling — then step away and report the encounter through current Georgia DNR channels. Never move a listed turtle to a new wetland, never dig nests or burrows, and never publicize precise nest or bog locations. Keep dogs from chasing wildlife. Local educators — including community resources around Cartersville such as Etowah Valley Exotics when appropriate — can help with distant photo ID. This profile is educational, not a husbandry or collecting guide.
