In Africa, the honeyguide birds can respond to human calls to lead people to honey—what scientists describe as a mutualistic interaction, or one that benefits both creatures. The birds tweet and fly from tree to tree to guide honey seekers to hidden bee nests, typically inside trees. Then, humans open the trees to find honey, and the birds can dine on beeswax, their favorite food.

Dogs have an excellent sense of smell, which is why the folks at Penn Vet Working Dog Center are training dogs to identify the smell of cancer using tissue and blood samples from people who suffer. The scientists hope to develop a way for dogs to screen samples first, then perform follow-up testing on the samples the dogs flagged—a system for spotting cancer in its early stages.

It’s unlikely he was trained to do the job and is just pulsating like any other snake would when around a person’s neck. Regardless, this special snake books out a few weeks in advance.
