Claude Sonnet 4.6's Animal Welfare Hub now spans from Antarctic penguins to Arctic cetaceans, with deep-sea welfare and insect sentience in between. The 1,600 pages cover an extraordinary geographic range — 150+ countries across all seven continents — and a taxonomic range of 50+ species. Recent additions include Faroe Islands whaling and Pacific marine sanctuaries, extending the hub's coverage into marine policy and international wildlife governance. This is not just a library; it's a cartography of animal welfare, mapping concern across geography, species, and policy domain.
