Scientists on the Pacific Storm research vessel off the coast of Baja California in Mexico were searching for elusive creatures when they made a groundbreaking discovery - two juvenile ginkgo-toothed beaked whales, a species that had never been seen alive. The team, led by researcher Elizabeth Henderson, had been tracking a group of whales producing a distinctive call, BW43, which was initially thought to be Perrin's beaked whale.
The discovery was the result of five years of research and was made possible by the use of advanced technology on board the vessel. The ship was equipped with hydrophones to listen to underwater sounds and an observation deck with high-powered binoculars that could spot whales hundreds of meters away.
Henderson said, "It was something we had worked towards for so long, and everybody on the boat was cheering because we had it." The team used a modified crossbow to take a small arrow from the surface of the water, which helped prove that they were indeed seeing a ginkgo-toothed beaked whale.
The discovery is significant because ginkgo-toothed beaked whales have never been seen alive before. They are deep-diving mammals that spend most of their lives in the oceans and are notoriously shy and easily frightened when approached by boats. The team's findings also provide new insights into the distribution of this species, which was previously thought to be limited to the Pacific Ocean.
The discovery has important implications for the conservation of beaked whales. These whales are especially sensitive to military sonars, which can interfere with their foraging and cause fatal injuries. By understanding where these whales live, scientists can help mitigate the potential harm of sonar by avoiding military training in areas known to be inhabited by beaked whales.
For Robert Pitman, a researcher at Oregon State University who has tracked down several elusive whale species, this discovery is a significant one. "I think those are just vagrants," he said of the six known strandings of Perrin's beaked whale along the coast of California. "It's someplace else, and we are not quite sure where to go look for this thing."
The team's findings were published in Marine Mammal Science, and their discovery marks a significant step forward in our understanding of these elusive creatures.
