The coelacanth was a fish that many thought had went extinct 70 million years ago. No fossils of this fish have been found since then. Imagine the surprise when a live specimen was found in 1938. It turns out the coelacanth is not extinct at all but lives off the southern coast of Africa and India. Since 1938 researchers have been looking for and studying these amazing fish. There are still lots of things we don’t know about the coelacanth, but researchers and ichthyologists are still looking for answers. Sally Walker did a great job detailing the hunt for these prehistoric fish. The way this book was written really builds anticipation for each discovery. I loved the many photos and illustrations and the details included by Walker. Highly readable nonfiction.
