This is a photograph of the coelacanth model on display in the Museum. The model is quite accurate, the coelacanth is bright blue in real life.
When the coelacanth was first rediscovered, scientists were amazed - they had thought it had been extinct for millions of years. Rewards were given for more fish to be caught, and many museums wanted a specimen of their own. Scientists began to worry that the coelacanth was being overfished - they didn't want to lose the fish they had just found.
Now models of the coelacanth are being displayed in the museums. They may not be the real thing, but they do not endanger any more fish, and they give you a better idea of what it looks like - real specimens begin to fade and can decay after a while.
