Today, most fleas are invisible to the naked eye. Even the largest is less than 10 millimetres long. This creature was 20 times larger than the most common species, coming in at an incredible 20 millimetres in length. A general rule with evolution is, the larger the species the more succesful it is. These giants show just how succesful the fleas were during the Mesozoic era. While they are significantly smaller today, they occupy all corners of the planet in hundreds of different species.
