    whales have something in their brain cavity that was considered valuable at the time, can’t remember what it was called or what it was used for but I think that was the equivilant thing they were going for in Avatar

      Whales have been used for a number of resources in the past.

      Oil from blubber was a big one, and used in everything from lamps to soap.

      Ambergris was a perfume base.

      Spermaceti, the substance in the head of sperm whales, was used for candles and also lamps, as it was a higher quality.
