Scyllarus pygmaeus has been assessed as Least Concern. This is because it is widespread throughout the Mediterranean and deemed too small to be economically viable. It has been widely confused with S. arctus, and when caught that to be juveniles of that species. Although there is very little population information, it is not thought to be threatened.
|Range Description:||This species is found throughout the throughout the Mediterranean (Lindley et al. 2004); as well as the Canary Islands, Cape Verde Islands and Madeira (Holthuis 1991).|

There is no overall population information available for this species. This is a common species and is captured in trawl fisheries.
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species is found between 5 and 100 metres (Holthuis 1991). This species lives on sandy and coralline substrates and Caurlerpa and Posidonia beds in the Mediterranean.|
|Use and Trade:||This species is not considered to be economically viable due to its small size (Holthuis 1991). If this species is accidentally caught as by-catch it is usually considered to be a juvenile Scyllarus arctus and thrown back into the sea (Holthuis 1991). Historically, this species was harvested in small quantities by artisnal fishermen, but its now considered to be very rare (Linares 2008 in Lloret and Riera 2008).|
It is unknown whether this species is being impacted on by any major threat processes. However, this species has experienced a local decline in Cape Creus, Spain, where it was previously caught in small quantities, but now it is considered to be 'very rare' (Linares 2008 in Lloret and Riera 2008).
This species has been listed by the Council of Europe as a protected species in the Convention on the Conservation of European Wildlife and Natural Habitats (Council of Europe 1979). Further research into the population demographics and potential threats is suggested as these data are lacking.
