The Toronto Zoo is home to a troop of majestic western lowland gorillas.
Visitors flock to the gorilla habitat, eager to see the great apes up close.
But many guests end up showing their phones and taking selfies in front of the enclosure glass.
The zoo realizes the gorillas are becoming irritated and agitated by all the phone cameras.
To protect the gorillas' welfare, they kindly request people stop holding up phones.
They explain the unnatural screens are overstimulating and stressful to gorillas.
For the animals' wellbeing, guests are urged to be more respectful when viewing them.
