The freshwater leech, Macrobdella decora, lives in slow moving freshwater and feeds on the blood of its prey (fish, frogs, turtles, and some mammals) with its front and rear suckers. The leech’s mouth sucker is able to break through the skin of the host and then releases an enzyme that numbs the affected area and then causes the blood to flow freely.
Macrobdella decora, known as the North American leech, is a particularly colorful leech with orange spots down its sides and an orange belly. It's pretty to look at but not particularly pretty to have stuck on your skin, and is very common across the continent.
