Amazing Algae eater 
The front half of the body is taken up by the cephalothorax, which means “head-chest.” It’s covered by a solid piece of shell that protects the shrimp’s head and most of its vital organs, like the heart, brain, stomach and reproductive system.
An Amano’s head comes to a sharp point, called the rostrum, that gives it the distinctive head shape of all shrimp and lobsters. From either side of the rostrum, the eyes poke out on movable stalks that let the shrimp look around for predators without moving and giving away their position.
Amanos also have two pairs of whiplike antennae that emerge from the front of the head. The antennae are sense organs they use to help them navigate their surroundings.
