Protozoan

ULF 49 is an unnamed species of aquatic creature found behind transparant membranes within the Impact Crater on Tallon IV. Physically, they resemble large cells or some form of sea slug, and are extremely similar to ULF 7, although it is unknown if the two species are at all related. Although these creatures cannot be scanned, they can be observed to have a strong heat signiture when viewed through the Thermal Visor. They will scatter if shot at, but cannot be harmed on account of the rigid membrane that encases them. Similar-looking cell-like objects can be observed floating behind transparant membranes within all three Leviathans explored during the events of Metroid Prime 3: Corruption, although these entities are blue instead of orange and never react to Samus's presance in any way.
