Now, scientists are adding one more behavior to the list: forming fast friendships. A new study shows killer whales can rival animals such as chimpanzees and macaques (a kind of monkey), and even humans when it comes to the kind of “social touch” that is a sign of strong friendship. Some ocean animals maintain social structures — including male dolphins (海豚) that learn the “names” of their close friends. But there is little proof about wild killer whales. That’s where drone (无人机) technology came in. Michael Weiss, a behavioral ecologist, teamed up with his workmates to launch drones, flying them 30 to 120 meters above a group of killer whales. That was high enough not to trouble the whales, marking the first time drones have been used to study friendly physical contact in whales. The researchers recorded over 800 examples of physical contact between individuals. Those included slippery hugs, back-to-back and nose-to-nose touches between pairs of whales. Other whales playfully threw young whales into the air, letting them fall into the water. Besides, the drone pictures showed clear preferences among individuals, usually for one “best friend” of the same sex and age. Take J49 and J51 — two distantly related young males aged 9 and 6 — for example. “Every time you see a group of whales, those two are right there communicating with each other,” Weiss says. The young led most of these interactions, rather than the older females or males. Older males in particular were less important. “The young individuals really seem to be the glue (胶水) holding the groups together, Weiss says. As individuals age, this gradual loss of “centrality” is known in many social mammals, including humans. That finding is “especially appealing” to biological
