Fiddler crab Of the two pincers of the male's fiddler, one is particularly large and the other is of normal size. It uses its small pincers to dig small animals out of the mud and put them in its mouth to eat, while the large pincers are used to show off to other members of its kind.
This crab lives on tropical beaches. At low tide, they crawled out of their holes and waved their pincers at each other, some raising their pincers like shields, others waving them, and others jerking both pincers. This act of displaying the pliers is a manifestation of this:
This sand is mine, get out of the way! ”
When the burrow is invaded by other crabs, some fiddler crabs make a grasshopper-like "chirping" sound, which is the sound it makes by rubbing its hard shell with its pincers.
Only male fiddler crabs have oversized pincers, which are used to show off fighting other males.
If another tide sweeper enters their territory, they will fight. Each crab tries to knock their opponent to the ground with their large pincers.
At high tide, each crab cuts a small round piece of mud and brings it back to its burrow. They burrow into the hole and lay down the mud as a lid to cover the hole. The bubbles are sealed in the hole, and the crab breathes in the air until the tide recedes again.
