If a 7 pound baby was consuming 301 tons of food,it could be compared to which animal?

I should have send this one in the "nature trivia" by the way (sorry DG).

Hint: eats 86,000 times its own weight in the first 56 days of its life.

I'm guessing some kind of insect larva. Maybe a silkworm caterpillar?

Close enough,Professor,it is the "polephemus moth larva".Many trivia sites are calling it the "biggest eater".other source.

Of course in this scenario, after the 7 lb. baby eats 301 tons in 56 days she loses her mouth and gets busy reproducing.
