Believe it or not, this animal is closely related to the elephant, even though it looks like a hedgehog. It’s covered in spines, and unlike the porcupine it loses its spine, it keeps it for its entire life. But this means that the mother goes through an extreme birth because it gives birth to a spiky baby. Once it hits the air, the spikes solidify. But the mother can have between two and ten babies per litter, which means that’s a lot of spikes to deal with (Live Science).
