Alpheus edwardsii is an Indo-West Pacific snapping shrimp that belongs to the Edwardsii species group within the genus Alpheus. Alpheus edwardsii commonly lives in pairs in the intertidal; Ming-Shiou (1994) found that the antennular flagellum plays an important role in pairing behavior in this species.

Alpheus edwardsii belongs to the Edwardsii species group within the genus Alpheus (Banner and Banner 1982). Type locality: Suez (neotype) (Banner and Banner 1972), types stored at the Muséum national d’Histoire Naturelle, Paris, France (MNHN). For additional descriptions, see Banner and Banner (1982), Chace (1988), Anker (2001).

Indo-West Pacific and Indian Ocean: Australia, Red Sea, Thailand, Philippines; likely throughout the Indian Ocean and Southeast Asia, Caroline Islands (Banner and Banner 1982, Chace 1988). (Banner and Banner (1972) note that earlier records should be viewed with caution, as this name has been applied to many specimens.

Maximum body size is 14 mm (carapace length) (Chace 1988). Specimens of what was first identified as Alpheus edwardsii were collected by Savigny while he was a naturalist on Napoleon's Egyptian campaign; Audouin (1827) applied the name Athanas edwardsii to the specimens, but the types have been lost. Banner and Banner (1972) established a neotype for A. edwardsii based on material from the Suez area. Anker (2001) notes that A. edwardsii and A. audouini (the latter currently a junior synonym of A. edwardsii) may be two distinct species. Color likely variable; one specimen from the Red Sea has been described as having a greyish green body with light sides, abdomen with 7 longitudinal rows of white spots, chelae bluish grey with pale fingers and brown tips (reported in Banner and Banner 1981).

This species is primarily intertidal, where it lives under rocks, in clumps of coral, and in sandy/muddy areas; it has been dredged from as deep as 26 meters (Banner and Banner 1982)

Alpheus edwardsii commonly lives in heterosexual pairs in the intertidal; Ming-Shiou (1994) found that the antennular flagellum plays an important role in pairing behavior in this species.

Classification of this species in the genus Alpheus is uncertain.
