Drei Löwen im Zoo von Tokio sterben an einem vermuteten Hitzschlag.

Three lions died at Tokyo's Tama Zoo after showing signs of suspected heatstroke, according to a press release issued by the zoo this week. The three animals, aged 3, 11 and 15 years old, all were born at the facility and exhibited severe dehydration and multiple organ failure during post-mortem examinations. The exact cause of death remains under investigation. The incident occurred amid a sudden spike in temperatures in Tokyo during mid-July. The zoo reported that most of its 16 lions began losing their appetite and becoming lethargic, with some requiring medical attention. Some of the affected animals recovered, while others worsened, developing severe symptoms such as an inability to stand and loss of consciousness. No other animals at the zoo displayed signs of illness, though staff have been monitoring them more closely. An official at Tama Zoo stated that public viewing of the lions was suspended on July 23 as their condition deteriorated. The zoo has continued efforts to treat the affected animals, including water-spraying and administering medication via intravenous drips. The extreme weather conditions saw temperatures in the area reach nearly 39 degrees Celsius (102 degrees Fahrenheit) in mid- to late July, prompting heatstroke warnings. Experts noted that lions are native to sub-Saharan Africa, where they are adapted to arid and hot climates. However, Tokyo's climate combines intense heat with high humidity, making it challenging for the animals to regulate their body temperature effectively. This environmental mismatch likely contributed to the health crisis among the lion population. The zoo has taken steps to manage the situation, implementing stricter care protocols and limiting public access to the enclosures housing the affected animals. Staff members have been working around the clock to provide appropriate treatment and monitor the remaining lions for early signs of distress. Despite these measures, the deaths highlight the vulnerability of non-native species to extreme weather conditions. Officials at Tama Zoo emphasized that while the immediate focus is on treating the surviving lions, long-term strategies will need to address how to better prepare for future heatwaves. Climate change has led to increasingly frequent and severe weather events, posing new challenges for zoos and wildlife facilities worldwide. As global temperatures continue to rise, institutions must adapt their animal care practices to ensure the well-being of both native and exotic species.
