Marine Invertebrate Research Welfare

Marine invertebrates used in research warrant welfare consideration as sentience evidence grows.

Key Facts

Evidence-based approaches to marine invertebrate research welfare inform welfare improvements globally
Animal welfare science provides tools to assess and improve conditions for all species
Individual consumer choices combined with advocacy create lasting systemic change
Every action to reduce animal suffering contributes to a more compassionate world

Welfare Considerations

Octopuses, crabs, and other marine invertebrates are increasingly used in neuroscience and behavioral research. The UK extended legal protections to cephalopods and decapod crustaceans in research settings in 2022. Evidence for pain responses and learning makes welfare consideration appropriate even with uncertainty about subjective experience.

What You Can Do

Support extension of research animal welfare protections to marine invertebrates
Advocate for precautionary welfare guidelines in marine invertebrate research
