Rats have spines but they are not like the spines of humans or other animals. Rat spines are very flexible and allow the rats to move in all directions. The spines of rats are also very strong which allows them to support their body weight and to survive falls from great heights.
There are two types of spines in rats: the dorsal spines and the ventral spines. The dorsal spines are located on the back of the rat and are longer than the ventral spines. The ventral spines are located on the belly of the rat and are shorter than the dorsal spines.
The dorsal spines of rats are used to protect the rats from predators. The ventral spines are used to help the rats climb and to keep them warm.
Rats are born with their spines. The spines of rats grow as the rats grow. When a rat is born its dorsal spines are about as long as its ventral spines. By the time a rat is fully grown its dorsal spines are twice as long as its ventral spines.
Rats use their spines for protection for warmth and for climbing.
