ORCAS or "Killer Whales" are very intelligent mammals ! They have great spirits and are a good sign of life in the ocean. Yes, they can be tricksters too ! I doubt they think of their act of taking the fish from the fishermen as "theft" more likely they give thanks that some human being has done their work for them !  Never knew why such beautiful creatures were called " Killer Whales" until I saw them snack baby seals off the rocks for their dinner.  Give thanks for them being in our waters and leave some fish for them !
