Five eyes and a claw-ended appendage made an unusual head
Opabinia, known from Canada’s Burgess Shale, lived during the Cambrian period. Its head had five eyes and a flexible forward-reaching appendage ending in a claw-like structure. The mouth faced backwards beneath the head, and the appendage could reach it.
Even picturing the arrangement takes a moment.
