I spotted this adult male Crab Ghost Crab on the beach at low tide early one morning on Sanibel Island. They are most active before sunrise. They eat coquina clams, mole crabs and goodies that wash up high on the beach.
Sanibel Island, FL Dec. 18, 2009 It was quite a surprise to see these little crabs scurrying around on the branches and roots of the red mangrove trees. They were quite shy and would move to the opposite side of the branch pretty quickly, I had to snap my pictures fast!
These little crabs literally walk on their tiptoes but they sure can move fast! Males have one much larger claw that they use to attract the attention of the females. So, I guess with fiddler crabs, size does matter! ;)
