[1] It lives in the Marquesas Islands and parts of the Indian Ocean, including the Seychelles, in association with a goby of the genus Amblyeleotris.

The rostrum of Alpheus randalli is half as long again as it is broad and the carapace is not laterally compressed.

The background colour of this shrimp is white or transparent with red bands and spots on the rostrum and both large and small chelipeds.

[2] Alpheus randalli was first described in 1981 from the Marquesas Islands in the Indian Ocean where it was found living at a depth of 18 metres (59 ft) in association with a previously undescribed species of goby in the genus Amblyeleotris.

It feeds by picking small invertebrates out of the substrate that has been disturbed by the shrimp or by taking mouthfuls of sediment and extracting edible organisms and detritus.
