This crab is so named because of the size of their claws. They get their food from the mud… and it’s their playground as well.
The crab picks up chunks of mud with its claws and places them in palps in front of its mouth. The mud is filtered through some fine hairs and… down the hatch!
Of course the male can only use one of his claws. The other is so big that it’s worthless for picking up mud.
He uses this claw to mark out territory… And why not, to attract female fiddlers.
When he wants to impress them he’ll shake his large claw around vigorously.
Several species of fiddler crabs coexist in the mangrove swamp.
Nevertheless, these ladies have no trouble telling their own gentlemen friends from the others.
The female crab accompanies the male crab to his shelter where nobody will bother them while they mate.
It’s also common to see two males fighting over a female crab at the border between their territories.
So many adoring bachelors, and all of them so virile, can only lead to squabbling.
