Hmm, let me remember from what I looked into before we came here.

They got sharp teeth inside their long beaks to eat smaller fish with, they can swim and jump fast, and can attack anyone within seconds if they aren’t being careful. Light refraction on the water does play a role of the way they hunt for prey.

(The last part did spooked Rose out as she squeaks in terror. She is having a hard time trying not to panic about narrow fish with sharp pointy teeth.)
