Let's call these "straight-back" shrimp. Later, we'll post "hump-back shrimp". (These are not the common names.) All shrimp photos were taken by Dave Bulloch.
Pink shrimp are the most common, the ones you usually find at the grocery store.
Grass shrimp, of course, are one of several speciesthat live in local grass flats. They do well in aquaria.
The common snapping shrimp are also called pistol shrimp. One greatly enlarged claw creates a sound that will stun small fish.
Just over 1 1/2 inches in length.
