You will never guess where I've been today

You are never to old to learn new things. It might not be much but I have learned today that there are Swordfish and also Sawfish.  I did not realize there were two. The differences include the former having a smooth pointed projection from its head, the latter having a serrated one. After some further research I have discovered various recipes for Swordfish but none for Sawfish. I found out most of my information from the Natural History Museum, a fascinating place to visit. I found they were poor on the recipe info though
