This little guy is super-cute. So let’s talk about something that little less cute: glands. Penguins have two specialized glands that help them thrive in such chilly environments. First, their supraorbital gland filters the salt out of sea water and allows it to be excreted by sneezing or through their bill. Second, their preen gland which produces a waterproofing oil that helps them stay warm and glide easily through the water.
