A Seerook is a flying creature native to SR388. It will only harm Samus if she comes into physical contact with one, even then causing only minor damage. Seerook usually fly mindlessly back and forth, hovering directly above the ground. They have three small spikes on both sides of their bodies, along with a rounded sucker-like mouth surrounded by teeth (much like the mouth structure of some of the later developmental stages of the Metroid).
