Crabs

Those small crabs master the art of camouflage, you can hardly spot them, usually on a rock, at the junction air/water.

Look at this tiny crab just over the water.

A pipefish

We spotted this fish in Byblos fishing and boating area.
It's a kind of syngnathus, also known as pipefish (in french : aiguille de mer ou poisson trompette).
