First leg subchelate (flat short claws ending in a finger fitting across an oblique palm). Fourth segment (merus) of first leg (pereopod 1) with a ventral spine. Second leg chelate and subequal in length to other legs. A single arthrobranch (gill) on maxilliped 3. Up to 1.5 cm long.
This introduced sand shrimp species was first collected in Australia in 2008 but is so far confined to intertidal sediments off Newport, Port Phillip Bay. As shrimps have pelagic larval stages there is the potential for them to be taken in with ships' ballast water and transported. Many Crangon species are described as prey or predators of flat fish.
Intertidal to 24 m.
Yellow Sea, northern part of the East China Sea, central and southern part of the Sea of Japan, and Japanese mainland.
