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.

Breeding: Females are fertilized internally.  The eggs form ovarian cysts, in which they develop.  When they hatch, the female gives live birth.  The young go through several planktonic stages.
