Tour of mangrove swamps

Following is a really nice mangrove swamp web page.
I especially like their "Halloween Crab".

One of the crabs on the above website also lives in the South Lido mangroves.
It is the mangrove tree crab or Aratus pisonii. .

This is one of only two species of crabs that can climb trees. It digs into the tree with sharp claws and can cling to tree bark as well as to wooden docks and pilings. The mangrove crab eats leaves and insect larvae in the mangrove trees
