Can you solve it? On the tiles with the new Escher

Puzzles that will leave you in (identical) pieces

UPDATE: Read the solutions here

Today's puzzles come from Alain Nicolas, a Frenchman who has been called the world's finest artist of Escher-style tilings. (That's to say, tilings with no gaps or overlaps in which each tile is in the shape of a living creature, as pioneered in the 1930s and 1940s by the Dutch artist MC Escher).

In each puzzle, you will be presented with an outline, such as the one below left. The challenge is to draw a line that divides it into a certain number of pieces of identical size and shape. In this case, the solution, with two pieces, is below right.
