Smooth snapping shrimp
Alpheus sp.*
Family Alpheidae
updated Jan 2020
Where seen? This short and stout snapping shrimp is sometimes seen on many of our shores, in sandy areas near seagrasses and among coral rubble. It is more active at night. During the day, these shrimps usually remain hidden in their burrows.

Features: Body length 4-5cm. The shrimp has a smooth body which is usually plain. The enlarged pincer is flattened but rounded, somewhat like a cartoon drawing of a muscle man. Often the 'finger' of the enlarged pincer is orange.

This shrimp is sometimes seen in a burrow with large brittle stars.

Several different species of snapping shrimps might have this appearance.
