Marine biologists are studying the sounds that fish make. They believe that sounds are key to understanding fish behavior. This audio story explores how listening to fish may also be a way to help protect fish. By studying the sounds that fish make when trying to attract mates and when breeding, we may be able to stay clear of them during those times to help them reproduce more productively.

As plants and animals reproduce over time, they are able to change and adapt to ensure or improve their chances of survival. The evolutionary goal of reproduction is paired with the concept of natural selection and survival of the fittest to determine who will reproduce. From colorful plumage to size, different species use different strategies to ensure reproduction and mate selection. The sand tiger shark has a unique strategy to ensure successful reproduction - and it depends on the timing of mating. Listen to learn more about the ultimate sibling rivalry while in the womb.
