Spotted Shrimp

Presentation

The spotted shrimp is a small decapod crustacean recognizable by its translucent carapace scattered with brown or reddish spots. It lives on coastal seabeds, often hidden in sand or among seaweed and debris. This species is widely distributed in temperate and warm seas, where it plays an important role in benthic food webs. It is also exploited by artisanal and commercial fishing in certain regions. Its common name refers to the characteristic spotted pattern visible on its exoskeleton.

The segmented body of the spotted shrimp measures several centimetres and has a semi-transparent carapace marked with small pigmented spots. It has five pairs of thoracic walking legs adapted for crawling and swimming, as well as long sensory antennae. Its colouration allows it to blend in with its sandy or rocky surroundings, providing effective camouflage against predators.

Characteristics

Indicative values: they vary by subspecies, sex and region.

Habitat and distribution

The spotted shrimp inhabits shallow coastal seabeds, particularly sandy areas, seagrass meadows, and rocky substrates. It is also occasionally found in lagoons and coastal brackish waters. Its range extends from the intertidal zone down to several dozen meters in depth.

Behaviour

This species has primarily nocturnal habits, hiding in the substrate during the day to limit exposure to predators. It moves by crawling along the bottom or by rapid swimming movements when threatened, propelled by flexing its abdomen. The spotted shrimp typically lives in scattered groups rather than in structured schools.

Reproduction

Reproduction occurs through external fertilization following mating, during which the male deposits a spermatophore into the female. The female then carries the fertilized eggs beneath her abdomen until the planktonic larvae hatch. These larvae undergo several molts before reaching the adult benthic form.

Peculiarities

The spotted pattern on its carapace is a distinctive feature that allows this species to be differentiated from other similar coastal shrimp. It molts regularly to renew its exoskeleton as it grows. Its camouflage ability is particularly well developed thanks to its variable pigmentation.

Threats and conservation

Overfishing and degradation of coastal habitats, notably through pollution and coastal urbanization, represent the main threats facing this species. Climate change and ocean acidification could also affect its populations in the long term. However, it does not currently have a concerning conservation status at the global level.
