orcAs are extremely intelligent check out what they do to fishing boats .they get injured stealing fish off long lines however they ram the shit out of boats ,they chew up rudders/centerlines . Terrifying f your below deck and hear them communicating then bumping the keel.
Back during whaling days it wasn’t uncommon for orcas to lead whaling ships on to gray whales knowing they were gonna be fed all the scraps. Very intelligent animal.
