160. Tetragonal Fiddler Crab (Gelasimus tetragonon)

Subject: The Tetragonal Fiddler Crab (Gelasimus tetragonon) lives in the tidal zones of mangrove forests and muddy marches of the Indo-West Pacific and the East coasts of Africa. These burrow digging crabs filter out detritus from the sand and mud during low tide, creating little mud balls. Males of these semi-terrestrial crabs have on one side a much larger claw.

Technique: The extremely wary crabs duck back in their borrows at the slightest detection of movement. To film their natural behaviour we posed our camera in front of the anticipated path of the crab. The camera was then controlled remotely using a dedicated app.
