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.
