A strange and rare group of orcas has stranded on a beach in Chile — the first event of its kind in 67 years and only the second ever recorded.
The orcas (Orcinus orca) belong to the "Type D" sub-group — a distinct group of orcas native to the Southern Hemisphere. Type D orcas are so different from other orcas that some scientists suggest they might actually be a completely separate species.
