Also known as Alpheid Shrimp, Fine-striped Shrimp, Goby Shrimp, Pistol Shrimp, Snapping Shrimp, Yellow Bulldozer Shrimp, Yellow-lined Pistol Shrimp.
Found usually in pairs or colonies living close to their holes that they share with various gobies of the genus Amblyeleotris and Cryptocentrus on coral and rocky areas over shallow estuaries, harbours and reefs.
They feed nocturnally on tiny invertebrates and zooplankton.
Length - 5cm
Depth - 1-5m
Snapping Shrimps usually share their holes with various Gobies. While the shrimps dig out their holes the gobies stand guard, as the shrimps vision is poor they usually keep one antennae in contact with their goby partner.
Snapping Shrimps have a large claw, which they are able to snap, giving a load cracking noise and at the same time this produces a large jet of water, used in defence to either deter or to knock out their prey. (edit) Ref: https://www.sealifebase.org/summary/Alpheus-ochrostriatus.html
