Other Common Names
Sand shrimp

At the Aquarium

Sandy Coast

Appearance

The shell surface is smooth and has drab coloration for blending in with sandy bottoms that they inhabit.

Habitat

Soft bottoms, from mud to gravel, commonly on sand

Diet

Crangon shrimp will eat fish larvae, including those of flatfish, worms, tiny crustaceans living in the sand, bivalve young or siphons

Life History

Spawning likely occurs in deeper, saltier waters. Females carry their eggs for several weeks, depending on temperature and other factors. A batch will have at least 1,500 eggs. These eggs hatch to planktonic larvae and have several metamorphic stages before settling to the bottom, likely to shallow, low-salinity areas such as estuaries.

Females grow larger than males, reaching lengths of 1.9 inches.

IUCN Status

Not Evaluated

Ecosystem & Cultural Importance

Predators of Crangon shrimp are other crustaceans, wading birds, and fish, including green sturgeon and commercially-important flatfish species. Flatfish species in particular, have a relationship with Crangon shrimp because the shrimp eat them in their larval forms, but the flatfish will then eat the shrimps when they grow bigger.

In San Francisco Bay, there is a bait fishery for Crangon shrimp.
Range
Vancouver Island, British Columbia to San Diego, California
On the Oregon Coast
Soft sandy bottoms from estuaries out to the mid-continental shelf.
Fun Facts
When disturbed, they will swim down into the sand, using their legs, and likely also their pleopods (swimming limbs).
