How to tell the difference between a coconut crab and a hermit crab. They look very similar to the blueberry hermit crab at first, but the coconut crab has protective spines near its eyes. Hermit crabs do not have these spines since they have adapted to retreat into a shell to protect their eyes. The coconut crab does not depend on a seashell as it gets larger. I still have yet to find a juvenile coconut crab adapting with a seashell.

Terrestrial hermit crabs live in the coastal forest where the treeline and coastline meet. They are the caretakers of the coastal forest. They mainly feed on plants, flowers, fruits and seeds in the treeline. They also help disperse seeds in the forest, specifically the screw pine tree seeds.
