From other sources
Distribution A. falcatus is frequently found along the Dutch coast from the Voordelta to the Wadden islands and, in lower densities, at the shallow Dogger Bank. Both A. swamrnerdami and A. falcatus are absent from the Oyster Ground. In the Delta area, the Dutch Wadden Sea and at the Oyster Ground A. falcatus is absent. [details]

Distribution All British coasts, but apparently not common. [details]

Habitat In the study area, this species occurs in fine to mediurn sand with a low mud content. In literature A. falcatus is also described from shell or muddy sand (Lincoln, 1979). [details]

Morphology This amphipod has a length of up to about 7 mm. lts colour is pale white with brown patches. The body is strongly compressed. The head has a well developed, slender rostrum. The eyes are moderately large in females and very large in males. A. falcatus differs from A. swammerdami (q.v.) because of the large claspers found on the robust third pereopod (Lincoln, 1979; Hayward & Ryland, 1990). [details]
