The Russian tortoise is also known as Afghan,
steppe, central Asian, four-toed and Horsfield's tortoise. They
fall under the Mediterranean category, which includes four other
species.
The range of the Russian tortoise is from southeastern
Russia
, through eastern
Iran
, northwest
Pakistan
and
Afghanistan
. Its habitat is often dry dessert area at high elevations, where
they can be found near springs and brooks.
The Russian tortoise has a rounded-oval carapace which is
flattened along the vertebral scutes. The average length is 6-8
inches, and its color can range from light tan to yellow-green to
olive, usually with brown or black markings on the larger scutes.
The plastron is usually blotched with brown or black on each
scute. Unlike the other tortoises known as Mediterranean
tortoises, the Russian tortoise does not have a plastral hinge
between the abdominal and femoral scutes. The rear marginal scutes,
on either side of the tail, are enlarged and often slightly
serrated, especially in the male. The tail of the male is larger
than the female and the tip is hard and bony. The skin is usually
yellowish-tan. The Russian tortoise is the only Testudo with four
claws on each foot.
The Russian tortoise is primarily a burrow-dweller. In the
wild they are only active for about three months out of the year,
emerging from hibernation in early spring (March-May). Once they
emerge, they immediately begin reproducing. In May or June the
female lays 2-6 eggs, and may lay two or three additional clutches
during the same season. In the wild the eggs incubate for 80-110
days and hatchlings emerge in August or September. In captivity,
eggs are incubated at 87 degrees F for 60-75 days. Hatchlings are
usually 1.25-1.33 inches (32-34mm) long. They do not reach sexual
maturity until they are 10 years old, and are not considered to be
full-grown until they reach 20-30 years of age.
The Russian tortoise remains active until June or July, then
its activity slows and it only emerges from its burrow at dawn or
dusk when the temperatures are cooler. Most food plants are gone
by this time and it begins feeding on dried grasses and twigs
prior to hibernation. Hibernation occurs at surface air and soil
temperatures of 32 F or less, with the below surface soil
temperature at 59 F. The ideal body temperature during hibernation
is 39 to 41 F. When body temperature rises to 46 to 50 F, the
tortoise emerges from hibernation.
While hibernation is important for long-term health of the
Russian tortoise, it should not be attempted with newly acquired
tortoises, or any tortoise that is not healthy. Every effort
should be made to diagnose and treat injuries and any disease or
parasite problems prior to hibernation. During hibernation the
tortoise's immune system is depressed and any heath issues it may
have can progress and possibly lead to death. Temperature
maintenance is very important during hibernation. At 39 F and
below, most disease organisms will stop multiplying, but at 45 F
they can continue to multiply, causing any disease process that
may be present to progress rapidly.
DIET
In the wild the diet of the Russian tortoise consists
entirely of herbaceous and succulent vegetation, including grasses
(dried and green), twigs, flowers, fruits and the flesh leaves and
stems of native and cultivated plants. During rainstorms, the
tortoise will drink from puddles and will usually pass urine.
During the dry season it relies on metabolic water supplies.
In captivity, the Russian tortoise's diet should be high in
fiber and low in protein and consist of dark, leafy greens,
grasses, common backyard "weeds" such as dandelion,
leaves and flowers of non-poisonous trees and shrubs such as Morus
(Mulberry) and Abutilon (Chinese Lantern). Foods offered should be
from uncontaminated areas not treated with pesticides. Fruit
should be offered sparingly to avoid an excess of sugar in the
diet. Both calcium and multivitamin supplements are recommended.
HABITAT
The captive environment for the Russian tortoise can consist
of a dry, escape-proof enclosure (using underground wire mesh) in
the summer and hibernation during the winter. The enclosure should
be secured with fencing over the top to prevent possible predators
from injuring the tortoise. Day temperature should be 80-90 F and
night time temperature should not go below 75 F.
Direct sunlight or UVB lighting is essential to their
health. Humidity should be maintained at 40-75%, and a shaded area
and a soaking area should be provided. Shell rot can occur if the
tortoise is kept in a moist climate on a moist substrate, so the
tortoise must be able to dry out completely most of the time.
Russian tortoises can be maintained singly or in groups, however
excessive male courtship can cause stress to females. It is not
recommended that different species of tortoises be housed
together.
SIGNS OF A SICK TORTOISE
Tortoises are especially susceptible to respiratory ailments
and nutritional deficiencies. Signs to watch for include lethargy,
bubbling from the nose, wheezing, swollen or closed eyes, lack of
appetite for more than 2-3 days, loose stools, soft shell or
abnormal shell growth or beak growth. Pictured below is a Russian
with multiple problems related to husbandry and nutrition.
