Spider Tortoise

The Spider Tortoise gets its name — in both Japanese and English — from the radiating light-brown and yellow markings across its dark carapace, which resemble a spiderweb. Endemic to southern Madagascar, this small tortoise reaches a maximum shell length of about 15cm, making it manageable in terms of space. Many individuals have a hinge on the front lobe of the plastron, allowing them to close up defensively when startled. They tend to be somewhat shy and sensitive to changes in their environment, so keeping them well calls for an experienced, attentive keeper.

About Spider Tortoise

The Spider Tortoise is a small species endemic to southern Madagascar, with spiderweb-like radiating markings on its dark shell. Reaching up to 15cm, it's best suited to experienced keepers.

7 things to know before welcoming a Spider Tortoise

  1. 1Named After Its Web-Like Shell

    The dark carapace is marked with radiating light-brown and yellow patterns that resemble a spiderweb — the origin of both its Japanese and English names. No two individuals share exactly the same pattern.

  2. 2A Small Species, Max 15cm

    Even as adults, Spider Tortoises reach a maximum shell length of about 15cm. This small size makes them manageable in limited space, though their enclosure should still be adjusted as they grow.

  3. 3Endemic to Southern Madagascar

    This species is found only in southern Madagascar. Recreating a dry, arid environment similar to its native habitat, with careful temperature and humidity control, is essential.

  4. 4A Hinged Plastron for Defense

    Many individuals have a hinge on the front lobe of the plastron, allowing them to draw into their shell when they sense danger. Handle them gently and let them get used to you gradually rather than forcing contact.

  5. 5Best Suited to Experienced Keepers

    Careful attention to temperature, humidity, and UV lighting is required, which is why this species is considered suitable for experienced keepers rather than beginners.

  6. 6Plan for a Long Lifespan

    With an estimated maximum lifespan of around 70 years, Spider Tortoises are a long-term commitment. Before bringing one home, consider whether you can provide care for its entire life.

  7. 7Diet and UV Lighting Needs

    A diet centered on vegetables and forage, along with UV lighting to support healthy shell and bone development, are essential. Make sure you can maintain consistent feeding and lighting care over the long term.
