Studies have shown that a variety of species “smile” to show their positive reaction to a stimulus. Several years ago, dogs and rats were studied in the first landmark study that proved smiles are more than a human characteristic.
Most avid dogs owners already know their dogs smile when they are happy and excited. It is one of the many traits that make a good dog so special.
But it turns out that mammals like dogs and rats may not be the only species to smile along with humans. Scientist now are suspecting that this reaction may go well beyond anyone’s prior expectations.
Scientists at the Monterey Bay Aquarium, the first aquarium to house great white sharks, are exploring whether these sharks also express facial expressions like a smile. If conclusive, it shows a degree of cognition across a wide range of species that very few thought was possible.
Who knows what else your pet is thinking!
