The Shriekers are named for their main attack method of using intense sound waves to stun prey, and then swooping in to devour their helpless victim. They are easy to spot even in thick vegetation, as their leaves are always swaying. When one detects prey, it bursts from the ground with a scream, then becomes invisible, reappears to fire a soundwave and repeats from step two. It can be spotted with the Dark Visor or Echo Visor. They are most effective when in groups.
