2. The picture below shows a lined chiton (Tonicella lineata) with its head at left and tail end at right (source: Wikipedia):
 This eyecatching animal invites us to count. 8 plates it has and 6 of them carry triangular marks. Its bright yellow spots are arranged with one spot at the head end and with 7 more on each side, altogether 15 yellow 'sunspots'.
When Metoro said mama it was
presumably because he identifed the chevron
pattern in the mama glyph type with
the
pattern of plates on a chiton. |
