Coconut Crab
Also known as the palm thief or the robber crab, the coconut crab is on record as the largest land-living arthropod on the planet. This crab has an incredibly powerful set of pincers which it uses to climb and crack open coconuts.
The coconut crab has a body that is divided into 4 distinct parts: cephalic lobe, forepart, trunk, and opisthosoma. These land-based crabs have organs that are structured differently on their body, much like that of an insect.
They are usually around 40 cm long and weigh in at about 9 kg. As expected, they mostly eat coconuts, but will also sometimes eat tortoise eggs, leaves, fruit, and even discarded shells of other animals.
