I read an interesting January 15, 2025 article by Bob Holmes at Knowable Magazine titled The Caterpillars that can kill you. One may thing that I will offer a caterpillar fact as something I learned from the article. Not so. I present a lizard fact:

[A] forerunner to the new blockbuster drug semaglutide — better known by brand names such as Ozempic and Wegovy — was based on a molecule extracted from a venomous lizard, the Gila monster.

I present a Gila monster for those of you (which included be before finding this link) who are not familiar with it.
