The non-indigenous window shell Theora lubrica Gould, 1861 (Bivalvia: Cardiida: Semelidae) in the delta area of the Netherlands
Basteria , Volume 83 - Issue 1-3 p. 52- 58
The non-indigenous bivalve Theora lubrica has been introduced to the southwestern delta area of the Netherlands. For several years, it has been misidentified as Abra nitida, a species with similar appearance. Theora lubrica differs from A. nitida in the presence of an internal ridge (from umbo to anteroventral margin) and a bifid cardinal tooth in the left valve. In native and newly colonised areas the bivalve is particularly a successful competitor at sites with periodical hypoxic conditions. Ecology and invasiveness are discussed.
