Yes.  And they are the top carnivores of their ecosystem only, which 
is primarily aquatic (except for example the unusual lion pride that 
hunts in and around the water.  There's always a non-conformist).  
Like most large carnivores, they eat what gets near them when they're 
hungry.  Heck, I saw a T rex eat a lawyer!:))
