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.
