The first organization, by its own description, dedicated exclusively to improving the welfare of the ~440 billion shrimp farmed each year, deploying humane electrical stunners and pushing producers away from cruel practices like eyestalk ablation.

Accelerates the academic field of wild animal welfare science through original research, grantmaking, and professional outreach to identify evidence-based interventions for improving wild animals' wellbeing.

Reduces the suffering of farmed fishes by researching, testing and implementing welfare improvements — chiefly better water quality and lower stocking density — with partner farms in India, where most of its work happens, and a small team in China.

Drives systems-level change for trillions of farmed and wild-caught aquatic animals by reforming seafood certification schemes and building the Aquatic Animal Alliance coalition.

Protects wildlife and habitat across nearly two million acres of the Amboseli-Tsavo-Kilimanjaro ecosystem on the Kenya–Tanzania border, using community-based Maasai ranger patrols, snare removal and work to resolve conflicts between people and wildlife.

Protects bats and their habitats worldwide through evidence-based conservation and cutting-edge research, recognizing bats as vital pollinators and pest controllers.

Builds teams of women rangers to protect wildlife and wild landscapes in Zimbabwe, Mozambique and Botswana, reporting more than 13.1 million acres under management and a 90% decline in elephant poaching in its Zimbabwe operations.
