Tortoises are crawling omnivores which live in the moderate climates of the temperate forest and temperate swamp, and the sweltering humidity of the tropical rainforest and tropical swamp. Its thick shell gives it 35% blunt damage resistance and 50% sharp damage resistance. Their small body size, built-in armor, and moderate health means that a hunter will need several shots to take one down.

They can often be seen engaging predators in fighting, and unlike other prey animals, they can emerge victorious.

Analysis

Tortoises are the single best animal for meat : nutrition input, or nutrition efficiency. This is due to their large yield relative to their low hunger rate. However, tortoises are not pen animals. They must be re-tamed every 7.5 days, or carefully slaughtered just before they become un-tame. Players may prefer to ranch animals like the ibex and horse, as they do not require nearly as much micromanagement.

Nutrition

When slaughtered, a tortoise yields 21 meat and 11 lizardskin as a baby; 36 meat and 18 lizardskin as a juvenile; or 70 meat and 25 lizardskin as an adult. 1 meat is worth 0.05 nutrition.

A tortoise's fertilized egg only provides 0.25, compared to the 1.05 nutrition of a butchered baby. Therefore, a tortoise should always be allowed to hatch.

An adult tortoise consumes 0.13 nutrition per day, and a fertilized female creates an average of 0.3 offspring per day.

When offspring are slaughtered as babies, a female tortoise will produce 0.32 nutrition of meat per day, giving an optimal nutrition efficiency of 242.6%.
If the offspring are allowed to grow to adulthood, they will consume an additional 0.27 nutrition per day, but will instead yield 1.05 nutrition per day as they are slaughtered, resulting in an optimal nutrition efficiency of 260.5%.

This does not consider the food required of male tortoises. A female:male ratio of 8.88:1 reaches an optimal fertilization rate. With this ratio of tortoises, you reach a "true" nutrition efficiency of 251.2%.

Some care must be used when managing tortoise eggs, as tortoises themselves are omnivorous and do not seem to discriminate against eating their unhatched young. Make use of restriction zones and hauling labor to pull freshly laid eggs away from animal pens and into safe hatcheries to maximize yield.

Combat

Turtles are poor animals for combat. They do little damage, and due to their low health scale, they aren't durable, either. Turtles can occasionally be seen beating much larger predators, such as lynx and coguars. This isn't because tortoises are great at combat, but rather a consequence RimWorld's combat RNG. Armor has a chance to completely negate damage, so turtles have a higher-than-usual chance to win. If tortoise dies, their corpse will usually be consumed right away.

Because of their low damage and high-ish armor, turtles can be used to train the Melee and Medical skills. A well-armored colonist can land many melee blows on a tortoise without much risk. This trains their Melee skill. A doctor can tend to the colonist's and turtle's wounds, which trains Medical. Rinse and repeat a few times until the poor beast finally dies. Note that beating up human prisoners is even less of a risk (prisoners do not fight back).

As manhunters, tortoises are trivial to deal with, due to their slow speed. If you have any sort of ranged weapon, kiting tactics can be used to easily defeat a tortoise pack. Even if you don't have a ranged weapon, you could run to the nearest door and close it.

*As of version 1.1.2610, all animals can be tamed. The percentage of likelihood of success depends on factors such as the Animals Wildness Percentage, Pawn Handling Skill, and others. More information can be found on the animals page.

When considering a population of equal numbers of male and female tortoises, these nutrition efficiencies fall to {{#expr:{{Meat Production|{{PAGENAME}}|baby|1|1}}/{{Nutrition Consumption|{{PAGENAME}}|baby|1|1}} round 3}} for baby slaughter and {{#expr:{{Meat Production|{{PAGENAME}}|adult|1|1}}/{{Nutrition Consumption|{{PAGENAME}}|adult|1|1}} round 3}} for adult slaughter.

With this ratio of tortoises, you reach a "true" nutrition efficiency of {{%|{{Meat Production|{{PAGENAME}}|Adult|{{#var:femaleratio}}|1 round 2}}/{{Nutrition Consumption|{{PAGENAME}}|Adult|{{#var:femaleratio}}|1}} round 3}}.

Make use of restriction zones and hauling labor to pull freshly laid eggs away from animal pens and into safe hatcheries to maximize yield.
-While tortoises are the single most nutritionally efficient animal in the game, they are not blocked by fences and so require taming upkeep every {{#expr:12 - 6*{{P|Wildness}} round 2}} days. This can potentially be worked around by slaughtering the tortoises just as they would lose their tameness, but this might require heavy micromanagement.
+=== Combat ===

Note that beating up human [[prisoner]]s is even less of a risk (prisoners do not fight back).
-Tortoises are fairly easy to tame. Tortoise ranching can be a rewarding experience as maintenance costs are low and fresh females can be constantly recruited in the right biomes. Though they will not explode into a dwarf fortress "2cat" style of overpopulation in the same way a few [[chicken]]s can manage to, players can still build up large tortoise farms and use them as a steady source of income.
-Alternatively they can be raised for doctors to train medical skills by euthanizing and/or for training the melee skill. Because of the creature's armor and low damage output, a [[plate armor|well-armored]] colonist can land many blows without much risk, quickly raising the melee skill substantially. One strategy is to allow warriors needing training in melee to fight, (but not kill) the animal, then for doctors to mend the creature's wounds, allowing them to train their skill, too. Rinse and repeat a few times until the poor beast has been tenderized enough to be given to the cooks for a nutritious final disposition.
+As [[manhunter]]s, tortoises are trivial to deal with, due to their slow speed. If you have any sort of ranged weapon, [[kiting]] tactics can be used to easily defeat a tortoise pack. Even if you don't have a ranged weapon, you could run to the nearest [[door]] and close it.
