I took a lot of photos of fiddler crabs. During the photography, I also saw other interesting crabs. One of them posted on the Digital Camera Malaysia magazine. Here are some photos for your viewing pleasure. But none of them seems to be edible.
The first one is a mud crab commonly found in mangrove forest. You can see them easily on the mangrove roots of muddy area. Sometimes, they may come to your drain after the flood. The pattern on its shell looks like a face.
Tree climbing crab (probably Cardisoma carnifex)? I saw it on a mangrove tree once. It is the ugliest crab that I’ve ever seen. Most crabs have flat body and distinct edge. This one looks more like a hard bun. If you ask a small kid to draw a crab, his drawing will look like the crab below. It is quite big and you can “see” that its shell is very hard.
