Let's face it, there are a lot of ways to eat and be eaten in the animal kingdom. Feeding ranges from the sponge-like mouth parts of flies to the flat molar-like chompers of clam-eating fish like black drum. If an animal or plant exists in the world, then something feeds in or on it. This is true of animals that drink blood, also called sanguivores (sang-wa-vors). Another word for this is hermatophagy (pronounced her- mat-oh-fay-gee). Any time you see the term "--phagy" at the end of a word it means "eating". Herma comes from the Greek word "haima" or "blood" and phagein or "to eat." For today's post I want to share with you the world of sanguivores or blood drinkers. There are more than you think, and even though you may already be squirming in your seat at the though, keep an open mind. Blood is little more than water with easily digestible proteins, lipids (fats), and nutrients. To humans blood is super taboo, and gross, we see blood as "disgusting" because we're taught that it's full of diseases and should only be seen in horror films. However, in nature blood is something not to be wasted or ignored. It's the "water of life" for some animals. Here are 12 of the most interesting.
Opossums Eat Ticks and Help Humans

Why Opossums Get Ticked-off
Let's face it, ticks are one of those creatures that everyone hates. Even I, the biggest nature nugget of them all, hate ticks. They're flat and creepy and they invade the private moist areas of the human body that only my doctor and I should have access to. As if that's not enough, they bury their mouth parts in our skin, latch on, and suck our life-blood all while possibly transferring diseases. This creates a real ick factor that keeps many people out of the woods altogether. However, there is some hope, namely because there is a cadre of creatures that eat ticks. There are the usual suspects of beetles, ants, centipedes, and other generalist eaters that wipe out ticks, but this list also includes chickens and ground fowl such as guinea birds and bobwhites. There's even an African bird called an oxpecker, which lives in sub-Saharan Africa that eats ticks off water buffalo and other hoofed animals (and who doesn't love that name!?). Well, since we're short on oxpeckers here in the Eastern US we have to rely on another creature to help us out, namely the Virginia opossum (Didelphis virginiana).
