Meet the World's Largest Arthropod:

The world’s largest Arthropod is the Coconut Crab – which can crack open coconuts with its giant claws.

Let's uncover their unique adaptations!

With a leg span of up to three feet, it is the largest land-living arthropod in the world.

They can also reach weights of up to 9 pounds!

Diet

With a taste for coconuts, fruits, and even carrion, these land-dwelling crabs are known to climb trees and crack open coconuts with their massive claws.

Coconut crab populations can become so large that they strip entire trees of their fruit, leaving little for birds and other animals to eat.

Temper

Despite their intimidating size, coconut crabs are not aggressive toward humans.

They are shy and nocturnal creatures

These crabs communicate through chemical signals, which they release to mark their territories and attract potential mates.

Impact on Ecosystem

They efficiently consume dead animals and seabird chicks, which can otherwise become breeding grounds for pathogens and parasites.

Habitat

Found primarily on islands in the Pacific and Indian Oceans, these crabs live in lush rainforests and along rocky shores.

These crabs are excellent swimmers and can survive in both saltwater and freshwater.

Survival Strategy

They bury themselves in the sand, exposing only their eyes, allowing them to blend in with their surroundings and avoid detection.

The world's largest arthropod has a lifespan of up to 60 years, and have an impressive ability to regenerate lost limbs.
