We were catching a plane from Cairns in Queensland, Australia, at the end of a long visit to the area. We arrived a bit early so took the rental car for a random drive down to the coast.
Someone spotted that there was a sign pointing to a Boardwalk across the mangrove swamps, so we parked and went exploring. It was a wonderful walk. We saw huge spider colonies, twisted mangrove roots in the mud, amazing walking fish and loads of birds.
Looking over the edge of the Boardwalk, we noticed tiny colourful crabs scuttling about on the mud. This is one of them – so, so colourful and in such contrast with the dull mud that they must have some cunning line of defence.
