Percnon gibbesi is a notably swift and rather shy species of crab that is usually found during the day in crevices or among rubble. It moves quickly and skillfully sideways, especially when it feels threatened, and swiftly retreats to hiding spots. Although it primarily feeds on plant matter like algae, it occasionally consumes animal remains as well. Overall, its behavior is strongly focused on caution, speed, and adaptation to the rocky habitat.
The nimble spray crab has a particularly characteristic appearance. This species is flat, narrow, and well adapted to its life in shallow, rocky environments due to its fluorescent patterning. Notably, its legs have a yellow-white striped pattern.

The nimble spray crab is neither dangerous nor toxic to humans. However, it poses a threat to the ecosystem in the Mediterranean as an invasive species.
The nimble spray crab is considered an invasive species in the Mediterranean, having spread significantly since the 1990s. Due to its high mobility, rapid reproduction, and few natural enemies, it can establish itself very successfully. In doing so, it competes with native crab species for habitat and food, which can alter local ecosystems. Despite its rather inconspicuous size, it has a noticeable ecological significance.
