The Chute Leech is seen in Metroid II: Return of Samus. They are found on SR388. It has a flat body and will lie dormant until Samus walks by. Its attack is to jump into the air and then glide down, swaying from side to side using its parachute-like body. Artwork seems to indicate that they have four eyes.
Metroid II manualEdit
"Usually they will lay quietly on the ground or in the liquid. But, when Samus comes close, they will jump up to attack, falling down like a leaf from a tree."
