Reading the June 10 issue, I was prepared to catch the Simpsonesque spoof (blunder?) in this article. Perhaps the creature had up to 748 legs, or possibly up to 752 legs, but not “up to 750 legs.”

Researcher Paul Marek of East Carolina University explains that Illacme plenipes has four legs per segment, except for segments 2, 3, and 4, which have one pair each, and three segments that don’t have any legs. So, an individual with 192 segments would have 750 legs. —S. Milius
