Way of livingdiurnal
Like all crustaceans, Hymenocera picta molts whenever it becomes cramped in its shell. Before the hardening of its new body, it is more vulnerable and spends a good part of its time hidden. This mechanism, very complex, allows the periodic renewal of the exoskeleton and part of the internal skeleton. It is also during the moult that the females become fertile.
Hymenocera picta is a crustacea living as a couple or alone naturally found in the vegetation. This species is carnivorous . Measuring only a few centimeters, this small species tends to be discreet and hide in the presence of larger neighbors.
In a constant quest for dominance, the dominant males of this species cannot stand each other. The battle between two individuals can be intense and violent. It will result in the submission and sometimes even death of one of the protagonists.
The cilia located on the legs and tail facilitate swimming, which is done in leaps when the abdominal muscles contract.
