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.

Learning through Observing: Social learning occurs across vertebrate species

Social learning is widely thought to be something done only by species with social lives. However, recent research is showing that even more solitary species participate in social learning. A team of researchers from Australia tested the ability of a solitary shark species to learn through observing and mimicking members of their own species. They found that these particular sharks are capable of learning in this way, which contributes to our understanding of these animals’ lives and what we can do to conserve them.

Flame retardant sharks?

Flame retardants are found everywhere from your house to your car. Unfortunately, these chemicals can accumulate in the environment, including the ocean. Once in the ocean, flame retardants can make their way into marine organisms. The researchers in this study wanted to determine if flame retardants are transferred from mothers to offspring in sharks.
