Armpits may be a ticklish place for humans, but for manatees (Order: Sirenia), armpits are good for nursing young! Manatees are mammals and nurse their offspring with mammary glands that are located under the pectoral flippers for over a year. Sketch and fact contributed by Karli Chudeau Source: Berta, A. (2012).

If you want to befriend a goat, better say cheese! New research shows that goats can distinguish between human happy and sad faces, and prefer the pictures of humans that smile! When presented with images of the two facial expressions, goats spent 50% more time approaching and nudging the happy-face photos. This has important implications…

In Kowloon and New Territory, Hong Kong, over 1000 free-ranging Rhesus macaques (Macaca mulatta) and Long-tailed macaques (Macaca fascicularis) live just minutes from the busiest part of the city!

Even among nature’s best dads, some are better than others! Marmoset dads who respond to infant distress calls quickly and early in their offspring’s life are more likely to have offspring that survive beyond 30 days and are also more likely to gain weight quicker than babies of less attentive dads. Researchers indicate this comes…

With a majority of their lives spent soaring at sea, the Laysan albatross is a poster child for energy-efficient flight. Wings spanning up to 7 feet and the use of dynamic soaring allow albatrosses to fly for hours without flapping their wings. Dynamic soaring exploits wind shear, or the variation of wind velocity that occurs…

Bighorn sheep have double layered skulls to protect themselves during (literally) head-to-head combat. Their horns can weigh up to 14 kg (30 pounds!). Males fight battles with their heavy heads and horns, sometimes to the death, to win access to females. Now that’s a heavy concept! Sketch and fact contributed by Lea Pollack Source: Bighorn…

These marine birds mate for life, but don’t spend much time together other than during the mating season, which is only 20-30 days long. Talk about difficult travel logistics: GPS trackers show that penguins…
