TripAdvisor announced it will no longer sell tickets to attractions that breed or import captive whales and dolphins as part of its animal welfare policy which was launched in 2016.

The company’s policy states that it will not sell tickets to events in which animals are “forced to perform demeaning tricks or other unnatural behaviors” or some experiences “where tourists come into physical contact with captive wild animals.” TripAdvisor cites elephant riding and tiger petting as 2 such examples of physical contact.

While TripAdvisor will not sell tickets to such attractions, it also will not remove any of these attractions from its review website.

Said President of TripAdvisor Experiences and Rentals, Dermot Halpin, “Our aim is not only to prevent future generations of whales and dolphins from being raised in captivity, but also to encourage the industry to move towards alternative models, like seaside sanctuaries, that will better provide for the needs of the current captive population.”

These attractions will be removed from the website by the end of this year. As of the writing of this article, tickets could still be purchased via the TripAdvisor website.
