Would a creature with a ceaseless hunger feasibly exist

Say one day humanity has found a planet that supports life. It's filled with luscious forest and barren deserts, and various ecosystems that resemble Earthly ones.

After a single year of researching a variety of the existing species, an unknown creature seemingly sparks out of no where and begins to utterly devour creatures non stop, leaving very little to no trace of the carcass behind, not even the bones. Scientist race to study this creature with every method and resource that they have but with the utmost caution.

In the day, the creature can be seen eating one animal then leaving for the next, however, in the night, it can be seen grazing on various plants and drinking water.

It has been concluded that at night, the creature goes through a state of uni-hemispheric sleep, meaning that the creature can have one side of its brain sleep at a time, before switching to the other side. The scientist have also concluded that a single one of these creatures can mark its territory to up to at least 50 miles wide.

Lastly, it has been recorded that after half a year of eating, it'll go to extremely remote location to hibernate for the rest of the year.

Why would such a creature evolve to essentially never stop eating For half of an entire year?
