Unknown Life Form 24 is an unknown species of animal native to Zebes. Resembling a rather large Sidehopper, it charges back and forth at its prey and is also capable of leaping extremely high into the air. While it may be related to the Sidehopper, it is much more durable than one, though Samus' Screw Attack can kill it instantly.

While this species is usually encountered alone, it has also occasionally been found in small groups, though which is typically the norm for social behavior in this species is so far unknown.
