Let me tell you why barnacles are cool.

1. They are pretty colorful when you look closely.

2. They are filter feeders so they can like this to try to catch food particles flowing by.

3. (Kids hide your eyes) They have the longest penis to body ratio of any creature on the planet. Because they are sessile they have to be able to reach quite a distance to deliver sperm to a nearby female.
