Greek Tortoise Care: Spur-Thighed Tortoise Guide

The Greek tortoise (Testudo graeca) — also called the spur-thighed tortoise — is one of the Mediterranean group’s most variable species, with at least a dozen recognised subspecies spread across the Mediterranean rim from Spain to Iran. Marcus has kept a small group of T. g. ibera in an outdoor pen for ten years and has views on which subspecies suits which climate. This is the dedicated guide.

The subspecies maze

This is where Greek tortoises get complicated. The species has been split, lumped, and re-split repeatedly as DNA work has revealed regional populations:

• T. g. graeca — North African (Morocco, Algeria, Libya). Smaller (12–18 cm); arid-adapted.
• T. g. ibera — Turkey, Balkans, Caucasus. Larger (18–25 cm); the most common in the European trade.
• T. g. terrestris — Middle East. Medium-sized.
• T. g. zarudnyi — Iran. Largest of the subspecies, up to 30 cm.
• T. g. nikolskii — Russia/Caucasus. Smaller variant.
• T. g. whitei — Tunisia, possibly Algeria. Often disputed taxonomically.

The practical implication: husbandry varies subtly. North African subspecies prefer drier, hotter conditions and shorter brumation. European/Caucasian subspecies tolerate cooler conditions and longer brumation. Always identify your subspecies before deciding on brumation length and humidity targets.

This guide uses T. g. ibera as the reference since it’s the most common in the European trade. Notes flag where other subspecies differ.

Adult size

• T. g. ibera: 18–25 cm shell length, 1.5–3 kg.
• T. g. graeca: 12–18 cm.
• T. g. zarudnyi: up to 30 cm.

Females are larger than males in most subspecies.

Outdoor pen

Same Mediterranean framework as Hermann’s with subspecies-specific adjustments. Standard outdoor pen for a single adult T. g. ibera:

• Footprint: 4×3 m minimum.
• Walls: 30 cm above, buried 15 cm.
• Substrate: grass with bare-earth patches. Less lush than Hermann’s pens; Greeks come from drier rocky habitat.
• Basking spots: south-facing flat stones. Greeks bask extensively.
• Shade: 30 % of pen. Important in summer; less critical than for forest-edge species.
• Hides: stone overhangs or wooden shelters in cool corners.
• Water: shallow dish, refreshed every other day.
• Plant for grazing: dandelion, plantain, mallow, clover, hibiscus, sow thistle.

North African subspecies (T. g. graeca) want drier conditions still — minimal grass, more bare earth/stone, more shade overall, less misting indoors.

Indoor housing

Same tortoise-table framework as other Testudo species:

• Floor area 200×80 cm for adults; 120×60 cm for hatchlings.
• Open-top design.
• Substrate: soil-and-sand mix (70/30) 5–7 cm deep.
• Basking spot 32–35 °C; cool end 18–22 °C.
• UVB tube, T5 HO, replaced annually.
• Multiple hides.
• Shallow water dish.
• Photoperiod 12–14 hours summer, 10 hours winter.

Brumation

Greek tortoise brumation varies dramatically by subspecies:

• T. g. ibera: 12–14 weeks, target 4–8 °C. Same as Hermann’s.
• T. g. graeca: 8–10 weeks, slightly warmer (6–10 °C). North African origin tolerates less cold.
• T. g. zarudnyi: 14–16 weeks, cooler (4–7 °C). Iranian/cold-tolerant.

Identify the subspecies before brumating. The full protocol is in our brumation guide.

Diet

Standard Mediterranean diet — weeds, leaves, edible flowers, almost no fruit, no protein. See our Mediterranean Tortoise Diet Guide for the full framework.

Greek-specific notes:

• Greek tortoises eat tougher, more fibrous material than Hermann’s in the wild. Lean toward older, drier weeds rather than tender young growth.
• They tolerate cactus pads (opuntia/prickly pear, thorns removed) well — closer match to native diet than soft greens.
• North African subspecies in particular benefit from more arid-vegetation foods like cactus, dry grasses, mallow leaves.

Behaviour

Greeks are bolder than Hermann’s in our experience — more willing to approach a keeper, more food-driven, more vocal during the breeding season (the “clicking” courtship call is louder than in Hermann’s). Males can be persistent breeders and may need separation from females outside the breeding season.

Single-keeping is fine. Pairs work in adequate space. Multiple males in a single enclosure rarely works — aggression spirals.

Health red flags

Same as other Mediterranean tortoises — pyramiding, respiratory infection, vitamin A deficiency, MBD. See our Turtle Health & Feeding Guide for full triage.

Greek-specific:

• Runny nose syndrome (RNS). Greek tortoises (particularly T. g. ibera) carry herpesvirus at higher rates than Hermann’s in some populations. Chronic intermittent rhinitis can be the visible sign. Vet diagnosis required; treatment is supportive rather than curative.
• Imported wild-caught issues. Greek tortoises have historically been wild-collected in large numbers; older animals in private collections may have parasites or RNS from their origins.

Legal status

Greek tortoises are EU/UK CITES Annex A — same as Hermann’s, with full Article 10 paperwork required. Practical points:

• Every Greek tortoise must have an A10 certificate.
• Some specific subspecies (e.g. T. g. nikolskii) have additional protection in source countries.
• The historic wild-caught Greek tortoise trade was substantial; older animals in private hands without paperwork may have been wild-imported decades ago.

Buying advice

• Article 10 non-negotiable.
• Identify subspecies before buying. Husbandry varies. T. g. ibera is the safest first Greek for most European keepers; North African subspecies are higher-difficulty.
• Hatchling prices: £150–500. Premium pattern locality types at the top end.
• Health-check the eyes and nostrils. RNS can be subtle but visible — clear nostrils, no discharge.
• Specialist breeder over pet shop.
