General Invasion History:
Patelloida striata has a broad native range in the Indo-Pacific from central Japan to the Caroline Islands, north of Papua New Guinea (Kurihara 2002; Academy of Natural Sciences of Philadelphia 2013). This limpet was reported to be abundant in Samish Bay, Washington (WA) in 1924, after the planting of Japanese Pacific Oysters (Crassostrea gigas) and was later seen on a shipment of oysters to Willapa Bay, WA (Kincaid 1949, cited by Hanna 1996 and Carlton 1979).

Invasion History on the West Coast:
Patelloida striata (as Acmea heroldi signata) was reported to be abundant in Samish Bay, Washington (WA) in 1924, after the planting of Pacific Oysters (Crassostrea gigas) from Kumamoto, Japan and was later seen on a shipment of oysters to Willapa Bay, WA (Kincaid 1949, cited by Hanna 1996 and Carlton 1979). This species did not established in Washington.
Description
Patelloida striata is a small limpet with a flattened cone-shaped oval shell, which has an apex at the anterior end. The shell is marked with concentric growth rings and strong ridges radiating from the apex. The shells occasionally reach 24-33 mm in size, but more often are a maximum of 12-18 mm. The color of the dorsal surface is dark to light brown, with streaks of white scattered along the rays. The interior of the empty shell is pearly, with a dark oval in the center, said to resemble the shape of an owl, typical of the family Lottidae (Owl Limpets). Description from: Abbott 1974, Kurihara 2002, http://www.conchology.be/?t=27&family=LOTTIIDAE&species=Patelloida%20striata, and http://www.femorale.com.br/shellphotos/detail.asp?species=Patelloida+striata+(Quoy+%26+Gaimard%2C+1834).
Kincaid (1949, cited by Hanna 1966 and Carlton 1979) identified their oyster-associated Japanese limpets as 'Acmea heroldi signata’ which Carlton equated with P. striata, which we have followed here. However, the same P. heroldi signata is now equated with P. signata, a reddish deep-water species in the P. pygmaea complex (Nakano and Ozawa 2005). Patelloida striata, P. pygmaea, and P. signata all occur near Kumamoto, Japan, the source region for the oysters. Patelloida pygmaea occurrs on the Pacific Oyster (Crassostrea gigas) (Nakano and Ozawa 2005), while P. striata seems to be more of an intertidal species (Kurihara 2002). However, in the absence of preserved specimens, the precise identity of these limpets is unknown.
