What eats a coconut crab?

Answer 1

Adult coconut crabs have no known predators apart from other coconut crabs and humans. Its large size and the quality of its meat mean that the coconut crab is extensively hunted and is rare on islands with a human population. The coconut crab is eaten by Southeast Asians and Pacific Islanders and is considered a delicacy and an aphrodisiac, and intensive hunting has threatened the species' survival in some areas. While the coconut crab itself is not innately poisonous, it may become so depending on its diet, and cases of coconut crab poisoning have occurred. For instance, consumption of the sea mango Cerbera manghas by the coconut crab may make the coconut crab toxic due to the presence of cardiac cardenolides.

Answer 2

Coconut crabs are primarily scavengers and will eat a variety of foods including fruits, nuts, plants, and even carrion. They are opportunistic feeders and will also consume smaller animals such as other crabs, insects, and smaller vertebrates. Additionally, coconut crabs have been known to feed on coconut flesh, which is how they got their name.
