EOL Text
Caprella mutica is found on a range of natural substrata such as hydroids and algae and artificial substrata including buoys, mooring ropes, boat hulls and floating pontoons. It is often found in association with Sargassum muticum.

Het oorspronkelijke verspreidingsgebied van het machospookkreeftje Caprella mutica ligt in Oost-Azië, bij Japan. De scheepvaart of de oesterkweek bracht de soort naar Europa. Het machospookkreeftje werd voor het eerst aan onze kust waargenomen in 1998, toen men exemplaren vond op boeien vóór de kust van Zeebrugge. Dit diertje heeft zich ondertussen ook verspreid naar de andere havens aan de Belgische kust. De soort verdraagt een brede gradiënt van temperatuur en zoutgehalte en kan ecologisch negatieve effecten met zich meebrengen door in competitie te treden met inheemse soorten.

The origin of the Japanese skeleton shrimp Caprella mutica is East Asia, near Japan. The species was brought to Europe trough transport in ballast water of cargo ships or together with oysters imported by the farming industry. The first specimens of the Japanese skeleton shrimp in Belgium were found in 1998 on buoys in front of the coast of Zeebrugge. During the following years the species spread to the other ports along the Belgian coast. The species tolerates a wide gradient in temperature and salinity and might have a ecological influence by competing with indigenous species.

Skeleton shrimps or caprellids have very slender bodies and a cylindrical shape. The head is bulbous with antenna 1 generally longer than 2. The appendages are reduced in number. The animal can be divided into a head, thorax or pereon and an abdomen. They tend to be slow-moving. Caprella mutica is a large caprellid amphipod. Males can be up to 5 cm long and females 1.5 cm. They are orange to red in colour and the brood pouch of the female is covered with dark red spots.The first record of Caprella mutica for the UK was in July 2000, from a fish farm in Scotland (Willis et al., 2004). The species' natural distribution is the coastal waters of the sub-boreal areas of north-east Asia (Willis et al., 2004). Little is known about the biology or ecology of this species. Each female can produce up to 150 hatchlings every 45-50 days. It was introduced to North America (Pacific coast) accidentally through shipments of Japanese oysters. The method of introduction to the UK is unknown, but likely to be via shipping and aquaculture. Caprella mutica has been found in high concentrations in marine Special Areas of Conservation (SACs) designated for their biogenic reefs. The impacts on these habitats, if any, is not known. Found in high densities especially during May to September. On the west coast of Scotland their abundance can reach 300,000 individuals per m² (Cook et al., 2007).

Caprellid, "Ghost" or "Skeleton" shrimps, so called for their skeletal appearance. Amphipod crustaceans, easily distinguished by the elongate stick-like body form and reduction of the abdominal appendages. Head is generally fused with pereonite 1. Pereopods on first 2 segments (pereonites) are most flexible and called gnathopods; gnathopods 2 being the largest, used in defense, feeding and substrate attachment. In many species pereopods 3 and 4 may also be reduced or absent. Gills on pereonites 3 + 4, rarely on pereonite 2. Pereopods 5 - 7 much smaller than 1 + 2, used for clinging to the substratum. In females, brood plates (öostegites) develop on pereonites 3 + 4. Much remains to be learnt about their biology, ecology and in many cases changing distributions.
