Hedgehogs are small, spiny mammals that are found in Europe, Africa, and Asia. They are nocturnal animals that are known for their unique defense mechanism of rolling into a tight ball when they feel threatened. Hedgehogs have a wide range of habitats, from forests to deserts, and they are even found in some urban areas. Although they are not currently considered to be endangered, their populations are declining in some areas due to habitat loss and fragmentation.
Hedgehogs are interesting animals, and one of the things that makes them unique is that they do not have tails. This is not to say that they are born without tails, but rather that they lose their tails during their first molt. This process, known as autotomy, is a way for the hedgehog to escape predators. The tail will grow back, but it will be shorter and less spiny than the original.
