An especially popular killer whale put a dead fish on his head, in a throwback to a fashion last seen in the 1980s.

Orcas have been spotted wearing dead salmon on their head like hats, a trend that hasn't been popular with the whales since the 1980s.

The fashionistas of the ocean have spoken, and it’s official -- salmon hats are making a comeback among orcas.
