The red-footed tortoise's climate in the northern part of the range changes little day to day and rarely gets too hot for them, so the tortoises do not need to practice any form of dormancy and can often forage all day long. The tortoises in Moskovitz's study area were most active after 3:00pm while many species from warmer climes would be most ...
Arizona Game and Fish has more than 100 captive tortoises that need homes. Here's why and everything you need to know about applying to adopt one.
The Jackson ratio is calculated by taking the weight of the tortoise in grams and dividing it by the cube of the length of the tortoise's carapace in centimeters. [1] This is essentially a value of the density of the tortoise in g/cm 3. The optimal value for this ratio is 0.21 with a range of 0.18–0.22 being acceptable for hibernation.

Yellow-footed tortoises are a large species – fifth-largest overall and third-largest mainland species, after the Aldabra giant tortoise (Aldabrachelys gigantea), Galapagos giant tortoise (Chelonoidis niger), African spurred tortoise, and Asian forest tortoise. Typical sizes average 40 cm (15.75 in), but much larger specimens are common.
The brain of a tortoise is extremely small. Red-footed tortoises, from Central and South America, do not have an area in the brain called the hippocampus, which relates to emotion, learning, memory and spatial navigation. Studies have shown that red-footed tortoises may rely on an area of the brain called the medial cortex for emotional actions ...
These tortoises may attain a length of 25 to 36 cm (10 to 14 in), [12] with males being slightly larger than females. A male tortoise has a longer gular horn than a female, his plastron (lower shell) is concave compared to a female tortoise. Males have larger tails than females do. Their shells are high-domed, and greenish-tan to dark brown in ...
