Animals that eat coconuts include bears, monkeys and other animals that eat plants and can access the coconut meat. In addition, an animal that is notorious for eating coconuts is the coconut eating crab
The coconut crab is one of the largest crustaceans on earth and can grow three feet across. It's native to the islands of the Indo-Pacific region. The coconut crab is nocturnal and is strong enough to crack open coconuts and eat its flesh. It also eats small mammals, fruits, carrion, fellow coconut crabs and its own exoskeleton.
Though humans aren't sure of the origins of the coconut, it is now grown on plantations in over 80 countries and is prized for its meat, "milk," oil, water and other products.
