  GALAPAGOS TORTOISES
Agonistic behavior in Geochelone in the Galapagos appears to be a ritualistic competition for height.
Nearly all are capable of retracting the head and neck within the carapace and protecting the anterior opening of the carapace by pulling up the forelimbs, which are covered with thick scales.
Feral goats, traveling across bare lava fields from the southern part of the island, have invaded and devastated the area which was once a haven for the last large population of the giant tortoises.

 Radiated Tortoises
Among the most distinctive and beautiful are those tortoises which have a "star" or "radiating" pattern on their carapace, and many people believe that of these, the rare Radiated Tortoise, Geochelone radiata, is the most distinguished.
Radiated tortoises are among the world's rarer tortoises, although they are not as rare as the closely related Madagascar tortoise Geochelone yniphora, or "Angonoka", of which there may be only a few dozen surviving in the wild.
We are all indebted to the institutions and individuals who have worked so hard to make this program a success, for without their efforts one of the most beautiful tortoise species, Geochelone radiata, the Radiated tortoise, might not be around today for the world to admire.

 Turtles at Rotterdam Zoo
Between 1997 and 2004 we bred Cuora amboinensis (31 specimens), in 1999: 3 Cuora trifasciata, and between 1999 and 2003: 57 Geoclemys hamiltonii.
For reintroduction purposes 206 Geochelone sulcata were bred; they all went to the SOS Sulcata project in Senegal.
In this former filter section we already kept 1.2 Geochelone radiata in an exhibit also measuring 600x300x150 cm, and this group produced 4 hatchlings in 2003 and the first one this year was born May 16.

 Redfoot Tortoise
The red-footed tortoise (Geochelone carbonaria) has been an enduring favorite in the herpetocultural trade for years.
Red-footed tortoises have challenging head movements that are a series of lateral jerks, by contrast, yellow-footed tortoises utilize a long sideways sweep in their displays (Auffenberg, 1965).

 African Spurred Tortoise, Geochelone sulcata - Client Handout
Introduction: Commonly known as the African spurred, furrowed, or Sulcata tortoise, Geochelone sulcata originates in the Sahel region of Africa, along the southern edge of the Sahara Desert.
Both sexes have large gular projections (forked protrusions under the neck on bottom of the shell), but the males, tend to be larger and more flared.
Housing: Geochelone sulcata should have a clean, dry enclosure with access to food and water, full-spectrum lighting, warm and cool areas, (allowing for thermoregulation), a simulated (or real) burrow or hide-box, and protection from predators or other hazards.

Geographical distribution and variation: Geochelone carbonaria is discontinuous in distribution, ranging from easternmost Panama and parts of Colombia, Venezuela and Guianas in the north, to the mouth of the Amazon, to Bolivia, Paraguay, and the northernmost part of Argentina.
Habitat: Geochelone carbonaria lives in mosaics of deciduous and gallery forest interspersed with savannah, while G.
Parallel research on tortoise biology, reproductive capacity and growth in the wild is also needed because so little is known about their population levels and ecology under field conditions.

ABSTRACT: Geochelone chilensis is similar in its ecology to Gopherus agassizii.
For several decades forests and deserts throughout the tortoises’; range have been affected by free-ranging livestock, mainly goats but also cattle and sheep.
Populations are consequently marginalized to places such as road edges, sand hills, edges of salt lakes, and rugged landscapes where livestock seem to have low impact.

Phylogenetic Relationships of the Galapagos Tortoise Geochelone nigra from Microsatellite and Mitochondrial DNA Data
Although the Galapagos tortoise, Geochelone nigra has been recognized for 30 years as a single species with sub-specific populations distinguished on the basis of morphology, the taxonomic relationships of these geographically isolated subspecies have remained unresolved.
Although morphological differences for carapace shape, maximum adult size, and neck and limb length have continued to form the basis for the Galapagos tortoise’s taxonomy, in many cases, the plasticity variation cannot be classified to subspecies based on morphology alone (Fritts 1984).

It is important for you to get the accurate information you need to keep and raise your Sulcata so you don't make some of the grave mistakes that I did when I first purchased my Sulcata.
This care sheet is a good beginner’s reference and might help to explain, in layman’s terms, some of the more technical jargon of the tortoise world.
Point of interest: for those of you who also have Leopard tortoises (Geochelone Pardalis), the care of the Leopard and the Sulcata is virtually identical.
