Exotic Pet Welfare

Hermit Crabs in the Pet Trade

Hermit crabs sold as pets have complex welfare needs that the pet trade almost universally fails to communicate to buyers.

Key Facts

Millions of hermit crabs are sold annually as low-maintenance pets, often in beach souvenir shops
Wild-caught hermit crabs frequently arrive dehydrated and have a lifespan of months in typical pet conditions
In the wild, hermit crabs can live 30 to 40 years and form social groups
Properly housed hermit crabs require marine and freshwater pools, substrate for molting, and appropriately sized shells
Painted shells sold in pet shops are toxic to hermit crabs and prevent shell exchange

Welfare Considerations

Hermit crabs sold as cheap novelty pets are among the most mistreated invertebrate companions. The gap between their actual needs and typical ownership conditions means most die within months of purchase. The suffering involved — dehydration, inadequate molting conditions, shell unavailability — is preventable with accurate information.

What You Can Do

Do not purchase hermit crabs from souvenir shops or pet stores that sell them as novelty items
If you keep hermit crabs, provide species-appropriate substrate, humidity, and multiple shell options
