Why do killer squids have beaks?

Question

I know they use it for eating but it just seems wrong that a creature that lives in the ocean should have a beak similar to a parrot's? How did that evolve? lol.. sad I know

Answer 1

The squid needs its beaks to kill struggling fish. The beaks are more like teeth of animals than the beaks of parrots, which use the beaks to crack seeds.

Answer 2

Because they evolved from birds that fell in the water. Duh.
