Shark metabolism may hold key to species survival
According to a new study by the University of Queensland, the internal energy flow of large sharks and rays could be essential to surviving climate change. University of Queensland Ph.D. candidate Christopher Lawson found that bioenergetics of sharks and rays will determine the animals ability to adjust to temperature changes in historical habitats “Shark and rays […]

IUCN Red List of Threatened Species keeps growing
More than 28,000 species around the world are threatened, according to the Red List of Threatened Species compiled by the International Union for the Conservation of Nature (IUCN).
