What is notable about coconut crabs regarding their movement capabilities?

Coconut crabs are particularly notable for their exceptional climbing abilities, which is why the chosen answer is correct. These large terrestrial crabs are equipped with strong legs that enable them to ascend trees with remarkable agility. They are often found in coastal regions, and their ability to climb helps them to access food sources, such as coconuts, which they can crack open using their powerful pincers. Climbing not only aids in foraging but also offers them protection from predators and a suitable habitat for reproduction.

While coconut crabs can move quickly on land, they are not known for running at high speeds like some terrestrial animals, making the option of running fast less relevant. They also lack the anatomical adaptations necessary for flying, as their body structure is not designed for flight in the way some other species, like birds or flying insects, are. In terms of swimming, while they are capable of doing so for short distances, they do not have the capacity to swim well or rely on swimming as a primary mode of movement. Therefore, the focus on their climbing capabilities highlights their unique adaptations and behavior in their natural habitat.
