What Animals Don T Have Bones. You might naturally think a powerful animal like a shark has sizeable bones, and not only that but a strong bone density too, particularly around the jaw. After all, some animals don’t have any bones at all (like jellyfish) and others just have a hard layer on the outside of their body (like crabs).
Recap on shark bones (and the lack thereof) there are hundreds of species of sharks. We use the space to keep proteins to make white blood cells (and some others). The great apes, despite their size, tend to have very small penis bones, and humans are the only ones to have lost them altogether.
They don't make white blood cells there, and they don't live as.
All mammals, except some sea cows and sloths have seven bones in their necks. Chimpanzees and bonobos, two of our closest cousins, have a baculum that is only around 6 millimeters long. This category also includes rays, sawfish, and skates. Which is not to say they don’t have hard parts;
