Pubity on Instagram: " Pigs have incredibly keen noses, with a sense of smell far stronger than humans thanks to a large number of scent receptors and a powerful snout built for rooting through soil. They can detect food underground, sense predators, and even pick up subtle chemical cues in their environment. This sharp smell is so strong that trained pigs have been used to find truffles and locate items with surprising accuracy. (roxxydepalma/ monicag_gch8 via ViralHog) #surprise"
