Pink Clawed Crabs & Yellow Crabs - Savusavu, Fiji

Was thrilled to see these crabs with pink claws and incredible designs on their shells. They would come out at low tide and pick through the sand where they extract tiny bits of food from it. The yellow crabs would often fight one another (I think for mating rights and/or territory).
They have incredible eyesight and run quickly back to their holes with any movement. They would take a good 45 seconds to emerge from their holes again before coming back to feed.
