Welfare of Giant African Land Snails in Captivity

Giant African land snails are popular pets with welfare needs that are often poorly understood, and they also raise biosecurity concerns.

Key Facts

Giant African land snails can grow to 30 cm and live 5-10 years
They are illegal to own in the US due to invasive species concerns
In Europe they are popular pets often kept in inadequate conditions
Their welfare needs include correct humidity, temperature, substrate depth, and calcium
They are social and do better when kept in groups rather than alone

Welfare Considerations

Giant African land snails in captivity face welfare challenges from inadequate substrate preventing natural burrowing behavior, incorrect humidity causing shell degradation and desiccation, calcium deficiency causing thin fragile shells, and isolation from conspecifics. As mollusks with nociceptors they have some capacity for pain responses. Improper handling causes physical damage. Owners often underestimate their lifespan and complexity of care. The welfare dimension is often overlooked due to perceptions that snails are simple animals.

What You Can Do

Research snail care thoroughly before acquiring any mollusks as pets
Provide deep substrate for burrowing and adequate calcium sources
Never release pet snails into the wild due to invasive species risk
Keep snails in appropriate humidity levels to prevent desiccation
