Betaeopsis aequimanus (Dana, 1852)
The small snapping shrimp betaeopsis aequimanus is native to New Zealand and is not recognizable as a "typical" banger at first glance. The color morphs of Steward Island animals found under rocks were solid brownish-red and olive-green on seagrasses. Richardson & Yaldewyn described the color as orange-yellowish or dark green with a lighter longitudinal line down the back.
Occurrence extends to the temperate waters of New Zealand and its neighboring islands. Betaeopsis aequimanus is found in shallow coastal waters mostly under rocks or between seagrasses in the tide. If the crackling shrimp is "drained" by the ebb tide, it is able to jump like amphipods to get back into the water.
Betaeopsis aequimanus is the type species of its genus.
The genus Betaeopsis currently includes only three scientifically described species:
Betaeopsis acanthops (Bruce & Iliffe, 1991)
Betaeopsis aequimanus (Dana, 1852)
Betaeopsis indica (De Man, 1910)
