Orcas may have been part of the sperm whale attack that inspired 'Moby Dick'

• Though it may seem modern, whales have been sinking boats since at least the 1800's.
• In 1820, a sperm whale sank a whaling boat. The lifeboats were later attacked by what may have been orcas.
• This story is said to have inspired the novel "Moby-Dick," and was adapted into a 2015 film. 

A pod of orcas has been terrorizing yachts in the Strait of Gibraltar for the last several years. The killer whales have sunk several boats and interacted with or damaged hundreds more.
