eat the roaches
prawn bears stalked eyes whereas cockroach does not?
its near its eyes
Hugely different organisms. External obvious differences: Prawns have swimmerets (pleopods), a tailfan (uropods flanking telson), rostrum, claws (chelated pereiopods), stalked eyes, long antennae, antennules. Grasshoppers have wings, large hind legs (femurs?), short antennae, unstalked eyes. Ignore morphology, if it's living underwater it isn't a grasshopper. ;)
It allows the crayfish to burrow into the river bed and leave its eyes protruding to look for danger.

well it all started out in a small little place called your mum, the sun was rising and your dad was with little missy pocock :) a cockroach therefore has 4 eyes, 5 noses and a leg.
In cockroach, various structures like antennae, labium, maxillary palps, labial palps , compound eyes, simple eyes etc., are sensory in nature.These structures contain various receptors like chemoreceptors, mechanoreceptors, photoreceptors, thermoreceptors, etc. These receptors contain units like ommatidia, sensilla and Scolopendra.
The hunter stalked silently through the forest, eyes trained on its prey.
Roaches have a pair of compound eyes, each made up of more than 2,000 individual hexagonal-shaped facets and each facet has its own optic nerve.
antennae (touch, taste) compound eyes (light and movement)
Cockroaches have compound eyes for sight, antennal flagella for sensing touch, as well as cerci that are all over it that allow it to detect air movement.
their chitinous exoskeleton ... sensory organs like antennae , compound eyes , anal cerci (that have receptors to sense vibrations ).......... are some of important features
