Nature can be brutal. But animals also help each other, sometimes in ways unimaginable to the human observers. For instance, take the case of killer whales and dolphins, two top marine predators. According to new research, these mammals appear to have forged a special relationship\u2014which scientists caught on camera for the first time.<\/p>\n

In a Scientific Reports<\/a> study published on December 11, researchers describe how killer whales, or orcas, collaborate with Pacific white-sided dolphins<\/a> to track and feast on salmon off the coasts of British Columbia, Canada. The partnership was far more sophisticated than the two species sharing a meal, the paper reported, as the tag team capitalized on the other\u2019s natural strengths.<\/p>\n

For example, orcas used dolphin echolocation cues to locate large salmon, which are typically \u201cprey that dolphins cannot capture and swallow whole,\u201d the researchers explained in a statement<\/a>.\u00a0 Once caught, the orcas broke down the salmon into smaller pieces to share amongst themselves,\u00a0giving dolphins the leftovers.<\/p>\n

Pesky dolphins? <\/p>\n

As with many of the best scientific discoveries, the researchers stumbled upon this partnership accidentally. The researchers initially hoped to investigate how and why the orca populations of northern Canada were thriving compared to their southern counterparts. But their work encountered an unexpected obstacle: dolphins everywhere.<\/p>\n

\u201cAt first you\u2019re like, \u2018Oh, get out of here. We\u2019re trying to do some research,\u2019\u201d Keith Holmes, study co-author and a geographer at Hakai Institute, recalled to CBC<\/a>, admitting at some point getting \u201ca little annoyed.\u201d<\/p>\n

But that soon changed once the researchers had a closer look. If anything, the orcas were following the dolphins, not the other way around. Using drones and suction-cup biologging tags, the team was able to get aerial and underwater footage of what was happening.<\/p>\n

For roughly two years, the team recorded 258 unique events of dolphins traveling near tagged orcas. As the researchers reviewed the clips, they were mesmerized by what they saw.<\/p>\n

Listen, catch, eat <\/p>\n

The orcas were \u201csort of spread out and pinging through the water in a much broader area than what the whales can search\u2014and the whale was listening,\u201d Andrew Trites, study senior author and a marine biologist at the University of British Columbia in Canada, told CBC.<\/p>\n

When the orcas read signs of large Chinook salmon in the vicinity, they quickly swam forward to deliver the killing bite, then shared the catch with their fellow orcas. After they were done, the dolphins arrived to feast on the leftover flesh and tissue.<\/p>\n

There were no signs of any aggression during the whole process, Trites explained, although the killer whales could easily kill a dolphin if they wished to. \u201cBy working together, killer whales can conserve energy and use the dolphins as radar-equipped scouts to increase their chances of finding large Chinook salmon at deeper depths,\u201d he added in the university statement.<\/p>\n

The dolphins get predator protection and consistent access to \u201cone of the ocean\u2019s most prized fish,\u201d Trites said. \u201cIt\u2019s a win-win for everyone involved.\u201d<\/p>\n

Collaboration or exploitation? <\/p>\n

That said, there could be other ways to interpret this situation, Janet Mann, a behavioral ecologist at Georgetown University uninvolved in the new research, told<\/a> Scientific American. For instance, it could just be that the killer whales are exploiting the dolphins\u2019 tracking abilities to find salmon, she said.<\/p>\n

\u201cI don\u2019t think it\u2019s been shown as cooperation because I think the standards for cooperation are a little bit higher,\u201d Mann added. \u201cIt\u2019s not like the dolphins wait for the killer whales to come and then they say, \u2018Let\u2019s go.\u2019\u201d<\/p>\n

The researchers appear to be aware of this caveat, as in concluding the paper, they note that the extent to which this is a mutually beneficial relationship would require further studies. Additionally, it remains unclear whether this partnership subsists year-round or is limited to when there are high-value prey like the Chinook salmon nearby.<\/p>\n

\u201cThis is just another piece of evidence of what kind of intricacies are happening out there,\u201d Trites said.<\/p>\n

Now, before you point out a certain something in the comments\u2014yes, this is technically a dolphin-dolphin collaboration. Orcas (Orcinus orca) belong to the oceanic dolphin family Delphinidae, as do Pacific white-sided dolphins. And yes, orcas are dolphins\u2014but they also qualify as whales. Toothed whales, to be precise.<\/p>\n","protected":false},"excerpt":{"rendered":"Nature can be brutal.
