Summary:
When endangered killer whales swim through the sheltered waters of Puget Sound, they leave behind traces of "environmental DNA" that researchers can detect as much as two hours later, a new study has found.

The findings, published today in the journal Frontiers, are surprising and significant. They not only provide a new non-invasive way to study whales, they may help scientists locate cetacean species that are known but have rarely been detected -- including certain beaked whales.
