That's interesting. Almost like the number of rattles on a rattle snake.

An immature Lithobiomorpha; I don't know genus & species. Note that it has only 9 pairs of legs and pedal segments instead of 15. This is because the Lithobiomorpha and Scutigeromorpha demonstrate "anamorphosis," hatching from the egg with less than the full adult complement of legs & segments, and they add both legs & segments at each molt, as they grow to maturity with 15 of both. The orders Scolopendromorpha & Geophilomorpha demonstrate "epimorphosis"; they hatch from the egg with the full adult complement of legs & segments and simply get larger at subsequent molts.
