Is this what you look like when you think about your work email, post-holiday season? River otters use land only as a latrine and a bed, snatching sleep during the daytime in dens or beaver lodges. Most hours are spent swimming, hunting fish, or playing in fresh and coastal waters, where they are widespread.

This mini-monkey could fit in a human’s hand: the pygmy marmoset (Callithrix pygmaea) may look like a tiny squirrel as it dashes through the rainforest canopy of South America, but this primate is actually the world’s smallest monkey. Weighing in at 140 g and growing to be 13 cm long, it has a tail that’s longer than its body—and while not prehensile, it helps this monkey balance in the trees.
