Processa edulis

Nocturnal caridean shrimp that changes color and inhabits seagrass beds.

Last updated

Males range from 12 to 34 mm in length, while females measure 25 to 52 mm.[1][2] The caridean shrimp known as nika shrimp, Processa edulis, lives in shallow Atlantic and Mediterranean waters.[3] During daylight hours it conceals itself, and after dark it forages for food within seagrass beds and eelgrass flats.[3]

Key facts and history

A tooth and a point tip the short rostrum, which does not reach past the eyes.[1] Astaxanthin and its esters cause the shrimp’s color change from white by day to pink or red with tiny white spots at night.[1] Nematodes, polychaetes, amphipods, isopods, ostracods, decapod larvae, foraminifera, molluscs, and fish eggs are among the small invertebrates it consumes.[4][2]

What the cited sources add

The DORIS account notes that about ten other Processa species exist in Europe.[2] The species is parasitized by two epicaridean isopods: the branchial bopyrid Urobopyrus processae and the abdominal bopyrid Pliophryxus philonika.[2] The DORIS account states that Processa edulis was heavily affected by oil from the Amoco Cadiz spill that impregnated the sand.[2] The proposed common name "crevette-autruche" (ostrich shrimp) refers to the genus's habit of burrowing head-first into sand using the last maxillipeds and front legs.[2]

The Latin name Processa means "that advances forward," possibly referring to its forward-burrowing behavior, and edulis means "edible".[2]
