Why are orcas attacking boats and is the behaviour spreading?

ramming boats, biting rudders and, in a few cases, sinking entire
vessels. Now it has been reported that a similar encounter has
happened off Shetland. Madeleine Finlay speaks to marine biologist
and orca expert Hanne Strager about what might be behind these
incidents and where our fascination with orcas comes from This

audio of the calls of a humpback whale, not an orca. This audio has
