Interesting.

What animals cannot be accurately depicted with 13 circles?

Pelican on a bicycle

  • More generally, any animal that cannot be drawn in 12 circles cannot be drawn in 13 circles when riding a bicycle. By recursion, no animal can be drawn when riding a stack of seven bicycles.

centipede

  • I think so. With 13 circles, I can’t figure out how you could represent more than 26 legs (and other features would be lost).

    • You can use perspective tricks to only show half the legs

      A mature house centipede has 15 pairs of legs. You can probably get the point across with a portion of that, and use two parts of a circle for 2 legs.
