Metal Accumulation in Sharks of the Caribbean

Pollution threatens marine life worldwide. Some of this pollution includes metals that build up in the tissues of marine life, including sharks. People around the world consume shark meat as a part of their diets. Caribbean reef sharks are commonly consumed by people throughout the Caribbean and South America, but a study on metal levels in their tissues had never been done. A team of researchers undertook this study to assess the danger to people and to better identify sources of pollution so that marine pollution can be better managed.

Sperm Whales Learned to Avoid Nineteenth-Century Whalers

Nineteenth-century whalers questioned why sperm whales were getting drastically more challenging to capture.

Sperm whales that have encountered whalers might communicate to other sperm whales how to avoid the dangerous whalers. This information transfer between whales could help them adapt to rapidly changing environments.
