Occurrence and behaviour of Paromola cuvieri (Crustacea, Decapoda) were recorded by means of the MEMO lander equipped with two digital cameras and deployed in the cold-water coral community of the Santa Maria di Leuca (Mediterranean Sea). A total of 14 individuals were observed at depths between 547 and 648 m; 10 in the coral habitat on coral mounds and 4 off the coral habitat on muddy bottoms. Thirteen specimens recorded were females, one male and all were shown to scavenge the bait. All the specimens carried a sponge on their exoskeleton using the fifth pereiopods. The specimens were distinguishable by the size and shape of the carried sponge. The present observations demonstrate both passive covering behaviour and active behaviour of discouraging approach and attack from competitors or predators, respectively. This study represents the first in situ documentation of Paromola cuvieri behaviour interacting with other deep-sea species in the Mediterranean Sea.
► Occurrence of Paromola cuvieri in the deep-water of the Mediterranean Sea was recorded.
► A lander equipped with two digital cameras was deployed in a cold-water coral community.
► Scavenger activity on the bait was documented for the first time.
► Carrying behaviour of sponge was observed in all the specimens recorded.
► Active behaviour of discouraging approach and attack from competitors or predators was documented for the first time.
