Biologists studying killer whales face the challenge of studying organisms that spend a majority of their time underwater. From extensive research, scientists have learned that killer whales have adapted their sounds to help them catch prey. Scientists are looking to do more research, but it's difficult to find the whales in the first place. Listen to learn more about the methods scientists use to understand killer whale noises.

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.
