Brief Summary

Overview

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.

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.

Physical Description

Morphology

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).
