Turns out that baby snapper (larvae) make "knocking" sounds that adults also use, which function to keep fish together in their schools. Read more here.

I'm always looking for the opportunity to use the term "pugnacious" - which is the perfect term to describe steamer ducks, who seem to love to beat up (and even kill) other ducks. It's not clear to scientists what these ducks are so angry about, but they are big and physically built for fighting.
