It's well reported that oil spill disasters can have a catastrophic biological and environmental impact. But to date, few studies have examined the effect of whole crude oil on senses of a marine vertebrate. A new study is the first to confirm physiological effects on stingrays – and their sense of smell in particular.

Many millions of years ago, we mammals veered from the path of Earth's other inhabitants by evolving a unique skill – the capacity to chew. This newfound ability to chow down on tough foods powered our warm-blooded metabolisms and is credited with much of our success over the past 60-70 million years. But recently, scientists are discovering some unexpected parallels in the animal kingdom, the latest example being an Amazonian freshwater stingray that likes to nibble away on aquatic insects.
