Walking Sharks Are Breaking the Rules of Evolution and Reproduction

This article from Discover Magazine explores the unique characteristics of walking sharks, also known as epaulette sharks, which can walk on land, survive low oxygen environments, and reproduce without wasting energy. These sharks have evolved to prioritize efficiency, allowing them to thrive in challenging environments. The study published in Biology Open reveals that female epaulette sharks can reproduce without any measurable increase in energy use, challenging existing assumptions about energy, evolution, and reproduction in the ocean.
