DNA from dolphin spit

Biologists have developed a new way of harmlessly collecting DNA from dolphins from their exhalations or "blow".

Understanding dolphin genetics is critical to the conservation of wild populations.

Current methods to collect dolphin DNA use a procedure which can be harmful.

Scientists hope the new technique, successfully used to extract DNA from aquarium dolphins, can also be used in the wild.
