I pestered Stitch London to let me knit something for their specimen jars and they said yes. Here is my creation along with other woolly beasties of the deep!
My fishy knit is a coelacanth (far left). You can read more about them on the Stitch London blog.
I'm a natural history geek and have always loved the story of the discovery that a presumed extinct species was living in the depths of the Mozambique channel. If you're interested in enormous old fish with anal fins I can recommend this book.
I'm pretty sure they sell it in the NHM shop. If you're at the museum on Friday night come and say hello. Lets hope the Bone eating snot worms haven't eaten the giant sloth by then.
