We all have certain images of what animals "should" look like in our heads, but the truth is that there are so many variations in nature that whatever we have in our minds is far from being a reflection of reality. For instance, we think of pigs as being pink with a little tail, but did you know that there's a species of pig that has four giant fangs? Here are 15 images of odd animals that will leave you scratching your head:
1. Budapest Highflyer
2. Damascus Goat
3. Tortoise Frog
4. Hammerhead Worm
5. Visored Bat
