In January 2019, an international team of scientists working off the tip of southern Chile got their first live look at what might be a new species of killer whale. Called Type D, the whales were previously known only from a beach stranding more than 60 years ago, fishermen’s stories, and tourist photographs.
Genetic samples the team collected will help determine whether this animal, with its distinctly different color pattern and body shape, is indeed new to science.
“We are very excited about the genetic analyses to come. Type D killer whales could be the largest undescribed animal left on the planet and a clear indication of how little we know about life in our oceans,” said Bob Pitman, a researcher from NOAA Fisheries’ Southwest Fisheries Science Center in La Jolla, California.
The team’s encounter with the distinctive whales came after they spent more than a week at anchor, waiting out the perpetual storms of Cape Horn off southern Chile. It was here that the scientists collected three biopsy samples–tiny bits of skin harmlessly taken from the whales with a crossbow dart–from a group of Type D killer whales
