East Mouse
East Mouse (Welsh: Ynys Amlwch) is an islet found off the north coast of Anglesey. It is found just a few hundred yards away from the town of Amlwch, for which reason the island is known in Welsh as Ynys Amlwch, meaning "Amlwch Island". The islet is tiny (a maximum 462 feet long by 200 feet wide) with a maximum area of only 1½ acres, and void of any significant flora and fauna.
The islet is one of three similarly named islands off the north coast of Anglesey, the other two being West Mouse and Middle Mouse.
