C got a rare present from his friend. It was a smoked sturgeon (mum of caviar). Although I thought it would be like a smoked salmon, it was completely different. The meat was quite firm and fatty (not greasy), maybe because of sturgeon breed in a very cold place. Compared with smoked salmon, it was a meat rather than a fish. The slice was also thicker and smoked more than salmon. I squeezed a lemon on it, grinded black pepper and put on a buttered bread. Delicious.

In Japan, we call sturgeon 'chou-zame' which means 'butterfly-shark'. Lots of people often misunderstand that sturgeon is a kind of shark because of the Japanese name and the shape itself. It looks very similar to shark actually, but it's not the same kind! There are lots of different stories where the name of butterfly comes from. A) The butterfly patterns will appear if the skin is polished. B) Each of the backbones has the shape of a butterfly. C) The triangle dorsal fin looks like butterfly.
