Crayfish Memes

The taxonomic chaos on full display! Nothing screams "biology" like the completely arbitrary decisions about which appendages count as legs. Top left: "Pedipalps aren't legs!" Bottom left: "Pedipalps aren't legs!" Right side: "Actually, pedipalps totally count as legs!" And don't get me started on the crayfish situation—"decapods" literally means "ten feet," but apparently we can't agree if claws are feet or not. This is why biologists spend half their careers arguing about classification systems while the organisms themselves couldn't care less. Thirty years of education just to debate whether that grabby thing is a modified leg or not. Meanwhile, physics people are naming particles after colors and flavors, and we think we're the serious ones.
