Dr Gunther von Hagens' plastination exhibition Animals Inside Out opens this weekend at London's Natural History Museum.
In the past some people have been upset with Dr von Hagens' exhibitions as he also uses humans (with their permission). He thinks this is the best way to teach us how complex our bodies are, but not everyone agrees. This display shows the structure of the shark that lies just beheath its skin.
There are 100 animals on display at London's Natural History Museum. As well as smaller animals like sheep and goats, the team have even plastinated an Asian elephant and a giraffe. You can see the detail of their bodies and get up close to the exhibits.
Dr Gunther von Hagens is a scientist, famous for inventing a technique to preserve the remains of things that have died. His interest in teaching us about how bodies are made has brought about his latest exhibition Animals Inside Out.
The technique he uses is called 'plastination', and it works by removing the fat and water from a body and replacing it with plastic, so it will not decay. Here you can see the huge muscles of this bull and it feels like plastic to touch.
Instead of preserving the muscles, the team have preserved the blood vessels of this ostrich. It shows how blood is pumped all over the body in tiny tubes called capillaries.
Look closely and you can see the vessels that carried the blood around this shark. The exhibition opens on 6 April and you can visit until 16 September.
This huge male gorilla was given to the scientist by a zoo after it died. You can really see by its muscular skeleton how strong they are: gorillas use these huge muscles for pulling down small trees to get to the fruit and leaves at the top.
