Opabinia is a strange extinct animal that lived during the
Cambrian period. Its fossils
were found in the Burgess Shale in the Canadian Rockies in British Columbia,
Like its contemporary,
Opabinia had segmented lobes on the sides of its body and a tail-fan, both
presumably used for swimming.
However, there are also important differences:
Opabina was much smaller at 1½ to 2¾ inches (4 to 7 centimeters) in
length, it had five eyes, and it had a very long hollow proboscis ending
in a claw-like structure.
there has been much debate about how to classify Obabinia, although it is thought
that the two are related.
Today Opabinia is usually considered to be a
Lobopod, a member of a group of segmented worms believed to be related to Arthropods.
