Killer whales and dolphins have been captured hunting together on camera, in what could be a scientific first. Footage published in the journal Scientific report shows the two mammals working together to catch salmon in the waters around Vancouver Island in British Columbia, Canada. Researchers believe this is the first documented case of cooperative foraging between dolphins and killer whales, who are actually the largest species of dolphin. "N…

A shocking study in British Columbia documented the amazing Orcas and Golfinhos-pilot Cooperation for salmon hunting. This alliance increases the efficiency of breeding in 40%, challenging what it was known about the interaction between marine predators. The article explains how the lack of salmon can be strengt…
Orcas are amazingly intelligent hunters: they create waves to push seals from ice floes and drive herring together into swarms. They can stun prey animals with tail strikes to eat them in peace. Now, an international research team led by Dalhousie University (DU) in Canada found out that the sword whales use the dolphin's underwater radar to find Chinook salmon. They themselves save a lot of energy – and leave their diligent helpers a juicy rewa…
Madrid.- It was known that whales and dolphins interacted in the waters of the Pacific Ocean but no collaboration had ever been observed between them. Now, for the first time, a scientific team has recorded a group of killer whales and dolphins hunting together and sharing the loot. The images, collected by Canadian scientists, show for the first time a group of orcas (Orcinus orca) and dolphins of white Pacific flanks (Lagenorhynchus obliquiden…
A recent study in British Columbia suggests that whales and dolphins could co-operate to hunt salmon. Through fine observations, scientists lift the veil on a surprising and revealing interspecies alliance of the intelligence of these marine mammals.
