What can killer whales do?

They can kill large amounts of fish and are very dangerous nearly as dangerous as sharks, they're not much like whales except the size. They have very sharp teeths for ripping the skin of other fish.
killer whales hunt small fish. they are nice creatures and do not hurt people . a killer whale is actually a dolphin. just like a dolphin they eat small fish. they get their name "killer" whale because of there massive size!
