Terrestrial hermit crabs live in the coastal forest where the treeline and coastline meet. They are the caretakers of the coastal forest. They scavenge on marine life and any dead animals washed ashore. They also feed on plants, flowers, fruits and seeds in the treeline. They also help disperse seeds in the forest, specifically the screw pine tree seeds.
Pandanus trees with spiky sword shaped leaves provide a perfect environment for the Coconut crabs to thrive.

Coconut crabs spend their day hiding in burrows. They venture out searching for food late at night. This juvenile was found crossing the road.
Have a great day!
