One to Make Your Sister Faint
Bombardier beetle
Probably one of the most interesting bugs that I know, considering the enormous debates on Creationism revolving around the complexities of the Bombardier beetle. Though, it is also one of the most disgusting. The list for disgusting bugs is rather long, but this little guy surely ranks high in the top 20 in my imaginary list.
There are over 500 species of the Bombardier beetle. Now, they may look like a normal beetle, but they have one very special defense mechanism that makes them unique. You see, they fire a mixture of chemicals from their special glands in their abdomen. While that would not be very incredible on its own, the mixture is of two different stored chemicals; hydroquinone and hydrogen peroxide.
When threatened, the two chemicals are mixed through two separate tubes with small amounts of catalytic enzymes and then it fires the primary weapon. The terrible smelling fluid that shoots out violently from the abdomen reaches the boiling point, 100+ degrees Fahrenheit, and makes a loud popping sound. Each time it does this it shoots about 70 times very rapidly. It is very painful on human skin.
