Two species of fish that live in extremely cold environments produce near-identical antifreeze glycoproteins, called AFGPs . Scientists have determined the origins of the AFGP gene in both species. Selected characteristics of the two fish species are provided in Table 1. Table 1. Characteristics of two fish species producing nearly identical antifreeze glycoproteins

Fish Species Order Location Evolutionary origin of the AFGP Gene
Boreogadus saida Gadiformes Arctic No sequence identity with trypsinogen
Dissostichus mawsoni Perciformes Antarctic Pancreatic trypsinogen
