Male giraffes taste female urine to detect fertility using a special organ in their mouths—it's nature’s version of an ...

Animal senses When a cat or mouse senses the chemical compounds secreted by other animals, it activates a special sensor in the nose called the vomeronasal organ.

The enormous difference between male and female sexual behaviour may be explained, in animals at least, by a tiny organ in the nose rather than by any gender difference in brain circuitry.

The vomeronasal organ, found in the noses of some animals but not in people or higher primates, is a key processing center for pheromones.

The vomeronasal organ, found in the noses of some animals but not in people or higher primates, is a key processing centre for pheromones.

It turns out this is also true for mice, according to an MIT study that also identified the brain circuit responsible for this distancing behavior. Plants & Animals Mar 31, 2021 0 308 ...

The vomeronasal organ, a vital sensory structure, had never formed inside this dog’s snout, and a related structure, the septum pellucidum, was also missing.

The tongue does not have receptors to taste or smell. Instead, these receptors are in the vomeronasal, or Jacobson’s Organ, which is in the roof of the mouth.
