Chadwick Beach Cotton Mouse (Peromyscus gossypinus restrictus)
The Chadwick Beach Cotton Mouse was a subspecies of Cotton Deermouse endemic to the Manasota Key peninsula in Florida. The subspecies is only known from a few sample speciments collected in the 1930s.
The Chadwick Beach Cotton Mouse was smaller and paler than the parent species; being about 7 inches in length with a cinnamon colored coat.
The animal is considered extinct after extensive surveys in 1984, 1985, 1988, and 1989 failed to find any specimens in the wild. Deforestation of its habitat, maritime forests and predation by feral cats are likely contributors to extinction.
