The violinist Karramarro (Uca mjoebergi), when he sees the female, usually excitedly agitates his big piece to attract her: You can repeat the movement up to 20 times. However, a new study has just revealed a new data on the behavior of the species. In fact, scientists have found that males also listen or spy on their competitors covertly to get to know the stays of crab females that might be couple.

To reach this conclusion, researchers have studied about 50 “encounters” or crab coverings. The results have been published in Biology Letters. As they have explained, although the female is not seen live, when a crab malt to another male, he begins to move his own yew. Save time in the match.
