This is tessellation shows translation symmetry, also called "slide symmetry" and "glide symmetry".

Technically, tessellations should not overlap. So, if we look at these fan / fish scale shapes as abstract, then this is a tessellation. If, however, we imagine that each penguin's feet are hidden behind the penguins standing in front of her, then this is not a tessellation. Tricky rules, huh!
