Quick answer
Coconut Crabs feed on coconuts, fruit, seeds and carrion, adjusting with season, age, and what is abundant in Tropical islands across the Indo-Pacific. That label is a preferred pattern, not every item an individual might sample.

Coconut Crab diet overview
Coconut Crabs (Birgus latro) are best summarised as Omnivore (coconuts, fruit, seeds, carrion). Anatomy and habitat (Tropical islands across the Indo-Pacific) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How coconut crabs find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Coconut Crab role in the food web
As consumers in their food web, coconut crabs move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild coconut crabs. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Range and habitat
Coconut Crabs inhabit Tropical islands across the Indian Ocean and Pacific Ocean, from the Andaman Islands east to the Cook Islands. Their preferred habitat includes tropical islands across the indo-pacific, where they find food, shelter, and breeding sites. Population density varies with prey availability, water access, and human disturbance. Protected areas and intact corridors remain essential for long-term persis
Physical characteristics and behaviour
Adult coconut crabs typically measure about 0.4 m in length and weigh Up to about 4 kg (9 lb). They can sprint at up to 4 km/h (2 mph) when hunting or escaping predators. Coconut Crabs are known for the world's largest land arthropod and tree-climbing island giant — social structure, daily activity, and seasonal movements all reflect pressures in their native environment.
