The walrus calves and beluga whales have been observed swimming in circles in their small tanks, and the bears, Arctic wolves, and foxes pace back and forth excessively and scratch at the walls. Animals Asia’s Animal Welfare Director Dave Neale said: 
 
 “Taking animals from their natural environments can never be defended, but when they’re rehomed in conditions like we’re seeing at the Grandview Aquarium it’s the worst possible situation. Animals Asia animal welfare director Dave Neale said in a statement: “There is no excuse for any animal to be trapped this way." “It is difficult for me to work with people that have chosen to house animals such as this bear in such poor conditions, but they were very open,” Neale wrote, adding that the zoo had already implemented some of his group’s recommendations, including providing piles of snow for its two polar bear hybrids. Neale said he doesn’t believe the zoo will shutter its doors anytime soon, but hopes that continued pressure will lead to “significant changes.” 
 
 “Make no mistake. In addition, critics have accused the aquarium of keeping beluga whales and walrus calves in spaces too small for them to express their natural behaviours, and keeping their bears in conditions that threaten the animals’ long-term wellbeing.
– His name is Pizza and he lives in a Chinese mall where visitors pose for selfies next to his glass enclosure and knock loudly to get his attention. Such is life when you're the "world's saddest polar bear," per the Daily Express. Pizza, a polar bear hybrid, is one of 500 animals living at Grandview Aquarium inside a Guangzhou shopping center, where critics say animals are housed in dimly lit rooms with few if any natural surroundings. PETA calls it "the saddest zoo in the world," asserting that animals "suffer from neglect, poor care, lack of stimulation, and lack of natural light." Foxes and wolves have been spotted pacing in their enclosures and scratching at walls, the group says. Animals Asia first drew international attention to the zoo earlier this year when it started a petition calling for the facility to be closed, reports Mashable and the Huffington Post. More than 270,000 people have added their signatures, leading zoo officials to adopt some of the group's recommendations, including putting snow in the polar bear enclosures, per a release. But more "significant changes" are needed, says Animals Asia's animal welfare director, Dave Neale. "Keeping animals in this way is not acceptable." Neale, who recently toured the facility and says Animals Asia has been asked to advise it, notes, "It is difficult for me to work with people that have chosen to house animals such as this bear in such poor conditions." But "if our experience has taught us anything—first you open doors, then you open cages." (A much-maligned zoo in Buenos Aires is shutting its doors.)
