Freshwater environments cover about 1% of Earth's surface while accounting for more than 10% of known species. Like many marine and terrestrial ecosystems, however, they are in distress. A new study looking at some of the denizens of freshwater habitats offers a stark illustration of this biodiversity predicament. Researchers assessed the status of 23,496 species of freshwater animals in groups including fishes, crustaceans such as crabs, crayfish and shrimp and insects such as dragonflies and damselflies, finding 24% of them at a high risk of extinction.

The Humboldt penguin population has dramatically decreased in areas along the central coast of Chile, making them one of the most vulnerable of the world's 18 penguin species and putting them at risk of extinction, experts warn. Last year, scientists surveyed two islands off the central Chilean coast and detected 842 breeding pairs or active nests. This year they found just one breeding pair. Paulina Arce, a veterinarian who specializes in penguins, says that penguin populations in all islands surveyed decreased or remained the same.

Populations of a vulnerable species of marine mammal, numerous species of abalone and a type of Caribbean coral are now threatened with extinction, an international conservation organization said Friday. The International Union for Conservation of Nature announced the update during the United Nations Convention on Biological Diversity, or COP15, conference in Montreal. The union’s hundreds of members include government agencies from around the world, and it’s one of the planet’s widest-reaching environmental networks.
