So, why are animals (mostly) getting smaller?

In 10 seconds? Climate change is leading to smaller body sizes and larger appendages (fins, tails, legs, wings) in animals, according to research. A rapid increase in temperature puts animals at risk of extinction due to inability to keep up with change.

What’s happening to animals in relation to climate change? Animals are changing aspects of their body form (morphology) as a result of increased temperatures. A recent study, has linked this to the thermoregulation in animals, which is the ability to maintain a body temperature within a specific range, even if different to the surrounding temperature.
