• Orangutans are smart enough to talk about things not immediately present, D-Brief notes.


• The Crux notes that chimpanzees apparently have not developed small talk.


• The remarkable evolution of the songs of humpback whales over time looks a lot like the evolution of pop culture among humans, I think. D-Brief reports.


• Vox notes how, in many ways, trying to understand and communicate with humpback whales is so close to SETI.


• This article at The Conversation looks at a recent adoption of a narwhal into a group of belugas. What does it mean about these species' social relationships?


• Gizmodo notes that, recently, the species of fish known as the cleaner wrasse passed the mirror test for self-awareness. What does this mean about fish intelligence? What does this mean about the test?


• Honeybees, it turns out, can add and subtract. Motherboard reports.
