How to recognize Leander plumosus ?

Leander plumosus measures between 3 and 3 cm. Given its small size, this species is commonly referred to as a "dwarf" animal.

Of elongated form, like all the shrimps, it has 5 pairs of legs and a segmented carapace at the level of the abdomen which ends in a tail in fan cut for swimming.

Like all crustaceans, Leander plumosus 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.

Leander plumosus is a crustacea solitary. This species is omnivorous with carnivorous tendency . Measuring only a few centimeters, this small species tends to be discreet and hide in the presence of larger neighbors.

n general, this species does not care much about other animals crossing its path.

The cilia located on the legs and tail facilitate swimming, which is done in leaps when the abdominal muscles contract.
