Odaraia is a genus of crustacean arthropod from the Middle Cambrian. Its fossils, which reach 15 centimetres (5.9 in) in length,[1] have been found in the Burgess Shale in British Columbia, Canada. 217 specimens of Odaraia alata are known from the Greater Phyllopod Bed, where they comprise 0.41% of the community.[2]
Odaraia bore a large pair of eyes at the front of its body,[1] and may have had two smaller eyes in between.[3] It had a tubular body with at least 45 pairs of biramous limbs, and its tail had three fins – two horizontal, one vertical – which were used to stabilise the animal as it swam on its back.[1]
