Similar Species
The tracks of Hawksbill Turtles and Green Turtles are distinguishable from one another. Hawksbill Turtles have front flipper marks equal or slightly wider than their back flipper marks, back flipper marks are widely spaced and curled, and the back flippers, belly and tail produce a zigzag pattern due to the turtle's alternating gait. Green turtle tracks have front flipper marks overlapping those made by the back flippers, they are paired, they have symmetrical front flipper marks, and a short distance between flipper marks.
