A male (silver) and female (brown) common European adder meet prior to mating. Scientists are just beginning to understand female sexual anatomy in snakes.

Why Did Scientists Wait So Long to Study the Snake Clitoris?

The delay is representative of a major problem in biology: Female and intersex animals are understudied compared with their male counterparts

The strategy an animal uses to track a scent depends upon a number of factors, including the animal’s body shape and the amount of turbulence in the odor plume.

Scientists Are Trying to Figure Out How Animals Follow a Scent to Its Source

Uncovering the varied strategies that animals employ could help engineers develop robots that accomplish similar tasks

Many animals like corals release eggs and sperm into the water on just the right nights of the month.

Whales are tricky to see from a satellite. Belugas, with their light skin standing out against the water, are a bit easier to spot.

Can Satellites Really Detect Whales From Space?

Distant identification of whales is improving rapidly, but finding the behemoth creatures is still surprisingly tricky

Australia’s Most Endangered Parrot Faces an Unusual Threat: Trees

Native vegetation blocks the birds’ ability to see approaching predators

Large felids such as lions and tigers cause more deaths than other predators like bears and wolves. Most fatal felid attacks occur in low-income areas and are predatory, with humans stalked as prey.

What 70 Years of Data Says About Where Predators Kill Humans

A new survey of attacks by lions, wolves and other big carnivores shows that people in low-income countries are at greater risk
