Presumably it penetrates to  this water area from time to time. It is not possible to find the species in museum Black Sea’s  collections  [Kobjakova & Dolgopolskaya, 1969, p. 298]. P. minutus was recorded by  Czerniavsky from Odessa, Black Sea: “Mus. Zool. Univ. Odess. (Prof. Marcusen).”  [Czerniavsky, 1884, p. 136].   Range. “The relative abundance of these oceanic crabs is more or less dependent upon the  prevalence of flotsam or of floating or swimming organisms to which the crabs may cling.  They are therefore found far more commonly on Sargassum in the Sargasso Sea area of the  North Atlantic than in any other part of the world. Records of their occurrence in other areas  are still too scattered and frequently too unreliable to justify the usual distribution note that  Planes is "found in all tropical and temperate seas."
