User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-5460283-20120906021128

I think I know why in the Raveinte (i hope i spelled that right) in its ecology completely destroys the island that it fed off. I think it did this to make a safe nursery for its young.

Benifits:

1: No large predators to eat the eggs (if there are any) or young.

2: The Raveinte has enough food by eating the inhabitants of the island to go through the proccess of nursing the young (like a dimetrodon).

I think some partial proof of this is it is extremely territorial most likely because it sees the hunters as a threat to its young.
