Crab excavations

This photo explains he odd patterns in the sand that I showed yesterday.  Little crabs come out of their holes in the sand and deposit little balls of sand that they have dug out of their burrows.  There must be quite a network of tunnels under the sand.  I wonder why they do not flood with water when the tide comes in and covers over this area, but the crabs are obviously doing fine.

This week we have photos highlighting the wildlife of Tanzania, Africa posted on our Viva la Voyage travel photo site.
