Behavioural studies on the green turtle ( Chelonia mydas) in the sea
Underwater observations of green turtles near Fairfax Island, Bunker Group, Australia, disclosed female behaviour patterns to avoid copulation, including a striking adpressed hind limb position; resting in a female sanctuary area; avoidance swimming; face-to-face confrontation, followed or accompanied by biting; and a ‘refusal’ position, with the female assuming a vertical position, her limbs widely outspread and plastron facing the male. Copulation activity precedes egg laying on Fairfax. Copulation lasts as long as 6 hr. Females outnumber males, who engage in multiple copulations. The ‘escort’ is a group of one to five males attendant upon mated pairs. Hatchlings feed on various invertebrates. Cleaner fishes groom adult female turtles
