This question already has an answer here:
Many years ago I read a book; I can't remember the name and I want to reread it. Can anyone help me out?
Settlers land on a planet and colonise it; they find this nasty creature that's a wee bit violent and start killing them all; later in the year, they discover that the creature was killing other smaller animals who later in the year turn into huge killing machines.
They then spend their time trying to survive from the new born creatures.
It was a great book but I can't remember the title.
