Physical 

Sand Shrimp can range in color from nearly transparent to mottled brown.  They can reach up to 7.5 cm in length at maturity, with a short rostrum and hook-like appendages.

Habitat

C. septemspinosa live in small burrows or eelgrass beds, and range from the Arctic to Florida up to depths of 300 ft.

Feeding 

Sand Shrimp are predatory scavengers.  They will sometimes attack weakened prey, but prefer to scavenge dead fish and other organic materials.
