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.

Brown Bats 101
You can't look at Halloween decorations without seeing bats hanging everywhere. They are often lumped with spiders and black cats and relegated to the "scary things" category. Like many "scary" things, bats really aren't that bad if you understand a little bit about them. This is why I want to introduce you to brown bats, a good place to start on your way to appreciating our bat neighbors. After all, Bat Week is October 25th-October 31st (Have you planned your party yet??)!

BATS AREN'T RODENTS
First, let's get this straight, bats are not rodents. If you question this simply throw a mouse in the air and see if it flies. Bats are the only flying mammals. The creature that comes closest are flying squirrels and they simply leap like demented nocturnal paragliders and then float around using the flaps of skin between their arms and legs as they go from tree to tree.
An Introduction to Bats and Echolocation (and Tools to Use in the Classroom)
Bats Can Be Identified Through Their Unique Echolocation Patterns, They Even Have Dialects

As an undergraduate my introduction to field research was through bats. I studied under Dr. John Leffler, a student of EO Wilson, and spent countless hours recording bat sounds and trying to match their sounds to visual patterns that were species specific. If my life had gone differently I might still be studying bats and hanging from ropes welding bat gates. Even though I moved on from bats, to birds, and then outdoor education, I still have a mad passion for them and bat programs are one of my favorites. Thus, I'll do a series of posts on bats in the coming months in tribute to these amazing flying mammals. Today let's start with echolocation.
