 Soprano pipistrelle

The soprano pipistrelle ("Pipistrellus pygmaeus") is a small bat that in taxonomy was only formally separated from the common pipistrelle ("Pipistrellus pipistrellus") in 1999.It is possible that these two groups diverged from one another in the Mediterranean, and that is why "Pipistrellus pygmaeus" has the ability to thermoregulate at temperatures as high as 40 degrees Celsius.
