Do Rats Have Bones?
WouterMost rats have two kinds of bones: their tail and collarbone. The tail has a variety of bones, called caudal vertebrae, and the average rat has 27-30 bones in it. The tail is flexible, allowing the rat to squeeze through small gaps and fit through tight spaces.
Because rats are able to squeeze through very small gaps, some people think that they don’t have bones. However, this isn’t true. Rats’ bones are attached to each other by cartilage. This allows them to fit through very small holes, but this flexibility would prevent them from bending their bones.
Rats also have small bodies, so their spines are firm. The thin shape of their body allows them to fit through small gaps, but their small bodies make them more prone to being overweight. In addition, because they’re not able to bend their bones to fit through small holes, their bodies are naturally shaped like cylinders.
Unlike many other species of animals, rats have tiny bones and are able to fit through very small holes. Because of this ability, there have been several myths about the structure of rats’ bones. Some people think that the rats don’t have any bones, while others believe that the bones are collapsible.
Rats don’t have collar bones, but they do have very flexible ribs. This allows them to wiggle through small gaps and squeeze through small holes without much difficulty. This flexibility is aided by the fact that rats lack a collarbone, and their cylindrical shape makes them ideal for wriggling through tight spaces.
