Self-healing Axolotl


When one of these creatures is damaged (cut, or having a limb torn off), coagulation begins immediately – and new cells start to develop. In the case of a missing limb, a layer of skin cells begin to form from the cells at the location of the trauma. Following this, new tissues begin to grow: the axolotl is remarkable for its ability to generate new blood vessels, sinews, muscle, bone and even nerves. The length of time it takes to grow a brand new limb? Just a few months.

Octopus


An octopus has three hearts. Two hearts are dedicated to pumping blood to the gills, while the other takes care of the rest of the body. Unlike humans, octopuses have blue blood. Their blood lacks hemoglobin, the protein that gives human blood its red color. Instead, they rely on the copper-rich protein hemocyanin to perform oxygen transport duties, as it is more efficient in low-temperature and low-oxygen environments.

Candiru are small, parasitic, freshwater catfish famous for launching themselves up the urethra of anyone foolish enough to urinate in the river, and getting lodged into the urinary tract because of the spines that run along their backs.
