Just as restaurants, clothing stores and offices around the world have had to close their doors to prevent the spread of the novel coronavirus, so have zoos, aquariums and animal sanctuaries. Some zoos have followed other industries by using online technology to keep life going. Many of them livestream animal activity to viewers, post behind-the-scenes photographs and videos, and conduct virtual fundraising.

Though the institutions have been closed to visitors, zookeepers must still go in to feed the animals and provide medical care and enrichment. In order to facilitate this activity, the zoos have taken on additional safety precautions to disinfect facilities and ensure the virus is not unintentionally spread among animals (as happened in the case of several tigers and lions that were infected at the Bronx Zoo). Some zoos are trying to keep animals on the same schedules they had before the lockdown. One aquarium in Japan asked people to participate in video calls with its garden eels in response to worries that the animals would become accustomed to the absence of humans and be skittish when visitors returned.

With no revenue coming in from visitors, some zoos have been concerned about being able to properly feed their animals if the shutdowns continue for a long period of time. A few news outlets have quoted zoo representatives, including ones in Germany and Indonesia, as saying that if the situation got bad enough, they might have to slaughter some of their animals to feed others, though there have not be any reports of that happening.

Here we round up photographs from zoos around the world taken during the height of the pandemic and shutdowns to show the varying ways they have responded.

On May 5, 2020, a zookeeper wears a protective mask to spray water on a Sumatran elephant (Elephas maximus sumatranus) inside its enclosure at Gembira Loka Zoo in Yogyakarta, Indonesia, during the country’s lockdown. According to media and the Indonesian Zoo Association (PKBSI), tens of thousands of zoo animals across Indonesia are at risk of food shortage because of a lack of revenue during the COVID-19 pandemic. The PKBSI launched a fundraiser to provide food to zoo animals. According to a story from the international news agency AFP, the situation got bad enough, the association was considering allowing zoos to feed herbivores to carnivores.
