Biology/Natural History: This is one of the most common subtidal shrimp in this area. It sometimes swims up into the water column, to at least 100 m off the bottom. Ovigerous females can be found in January-February and May-September. They bear about 2200 eggs.

Parasites include the branchial parasitic isopod Argeia pugettensis (especially in Puget Sound) and the rhizocephalan barnacle Mycetomorpha vancouverensis.

The genus Neocrangon is separated from Crangon by the fact that Crangon has an arthrobranch gill on the third maxilliped and one median spine, while Neocrangon does not have the arthrobranch gill on the third maxilliped but does have the single median spine. Butler (1980) notes that along our coast this species does not have the arthrobranch gill but it has two median dorsal spines instead of one. On this basis, Butler (1980) decided the separation of

the two genera is invalid and called this species C. communis. Lamb and Hanby (2005) also follow this nomenclature.
