== Analysis ==
 
Tortoises are the single best animal for meat : nutrition input, or ''nutrition efficiency''. This is due to their remarkably low hunger rate. A tortoise farm can also produce a lot of leather. However, tortoises are not [[pen animal]]s. They must be re-tamed every  {{#expr:12 - 6*{{P|Wildness}} round 2}} days, or carefully slaughtered just before they become un-tame, which requires a lot of micromanagement. Players may prefer to ranch animals like the [[ibex]] and [[horse]], as they do not require nearly as much work to farm.
 
 
 
===Nutrition===
 
When slaughtered, a tortoise yields {{#vardefineecho:baby_meat|{{Meat Leather Curve|{{#expr:{{P|Body Size}}*0.2*140}}}}}} meat and {{Meat Leather Curve|{{#expr:{{P|Body Size}}*0.2*40}}}} [[lizardskin]] as a baby; {{Meat Leather Curve|{{#expr:{{P|Body Size}}*0.5*140}}}} meat and {{Meat Leather Curve|{{#expr:{{P|Body Size}}*0.5*40}}}} lizardskin as a juvenile; or {{Meat Leather Curve|{{#expr:{{P|Body Size}}*140}}}} meat and {{Meat Leather Curve|{{#expr:{{P|Body Size}}*40}}}} lizardskin as an adult. 1 meat is worth 0.05 nutrition. A tortoise's [[Tortoise egg (fert.)|fertilized egg]] only provides {{Q|Tortoise egg (fert.)|Nutrition}} nutrition, compared to the {{#expr:{{#var:baby_meat}}*0.05}} of a butchered baby. Therefore, a tortoise should always be allowed to hatch.
 
  
An adult tortoise consumes {{P|Real Hunger Rate}} nutrition per day, and a fertilized female creates an average of {{#expr: {{P|Eggs Per Clutch Average}}/{{P|Egg Laying Interval}} round 2}} offspring per day.
+
They can often be seen engaging predators in fighting, and unlike other prey animals, they can emerge victorious.
* When offspring are slaughtered as babies, a female tortoise will produce {{#expr:{{Meat Production|{{PAGENAME}}|baby}} round 2}} nutrition of meat per day, giving a potential nutrition efficiency of {{%|{{Meat Production|{{PAGENAME}}|baby}}/{{P|Real Hunger Rate}} round 3}}.
 
* If the offspring are allowed to grow to adulthood, they will consume an additional {{#expr:{{Nutrition Consumption|{{PAGENAME}}|adult}} - {{P|Real Hunger Rate}} round 2}} nutrition per day, but will instead yield {{#expr:{{Meat Production|{{PAGENAME}}|adult}} round 2}} nutrition per day as they are slaughtered, resulting in a potential nutrition efficiency of {{%|{{Meat Production|{{PAGENAME}}|adult}}/{{Nutrition Consumption|{{PAGENAME}}|adult}} round 3}}.
 
This does not consider the food required of male tortoises. A female:male ratio of {{#vardefineecho:femaleratio|{{#expr: 2/3*24*{{P|Egg Laying Interval}}/{{P|Mate Mtb Hours}}}}}}:1 reaches an optimal [[Animals#Mating|fertilization rate]]. 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}}. For reference, the next best animal, the [[chicken]], has a nutrition efficiency of {{%|{{Meat Production|Chicken|Baby|2}}/{{Nutrition Consumption|Chicken|Baby|2|1}} round 3}}, after considering their female:male ratio. Chickens do not produce leather. The next best animal that produces leather is the [[ibex]].
 
  
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.

When slaughtered, a tortoise yields {{#vardefineecho:baby_meat|{{Meat Leather Curve|{{#expr:{{P|Body Size}}*0.2*140}}}}}} meat and {{Meat Leather Curve|{{#expr:{{P|Body Size}}*0.2*40}}}} [[lizardskin]] as a baby; {{Meat Leather Curve|{{#expr:{{P|Body Size}}*0.5*140}}}} meat and {{Meat Leather Curve|{{#expr:{{P|Body Size}}*0.5*40}}}} lizardskin as a juvenile; or {{Meat Leather Curve|{{#expr:{{P|Body Size}}*140}}}} meat and {{Meat Leather Curve|{{#expr:{{P|Body Size}}*40}}}} lizardskin as an adult.
  
=== Combat ===
+
Tortoises do not layer unfertilised eggs, and as their [[Tortoise egg (fert.)|fertilised eggs]] only provide {{Q|Tortoise egg (fert.)|Nutrition}} nutrition compared to the {{#expr:{{#var:baby_meat}}*0.05}} nutrition of the butchered baby tortoise, they should always be allowed to hatch.
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 [[cougar]]s. This isn't because tortoises are great at combat, but rather a consequence of RimWorld's combat RNG. [[Armor]] has a chance to completely negate damage, so turtles have a higher-than-usual chance to win. And if a tortoise loses, you usually won't see their corpse (it'll 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 [[prisoner]]s is even less of a risk (prisoners do not fight back).
+
An adult female tortoise consumes {{P|Real Hunger Rate}} nutrition per day. If her offspring are slaughtered immediately, a female tortoise produces {{#expr:{{Meat Production|{{PAGENAME}}|baby}} round 2}} nutrition of meat per day, giving a nutrition efficiency of {{#expr:{{Meat Production|{{PAGENAME}}|baby}}/{{P|Real Hunger Rate}} round 3}}. If the offspring are allowed to grow to adulthood before they are slaughtered, they will consume an additional {{#expr:{{Nutrition Consumption|{{PAGENAME}}|adult}} - {{P|Real Hunger Rate}} round 2}} nutrition per day, but will instead yield {{#expr:{{Meat Production|{{PAGENAME}}|adult}} round 2}} nutrition per day as they are slaughtered, resulting in a nutrition efficiency of {{#expr:{{Meat Production|{{PAGENAME}}|adult}}/{{Nutrition Consumption|{{PAGENAME}}|adult}} round 3}}. 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.
  
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.
+
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.<sup>?</sup>

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 or for training the melee skill. Because of the creature's armor and low damage output, a 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.

Their heavy armor and small size makes them a decent combat animal despite their low damage output, easily occupying attackers' time, and they may even survive to down a raider. Their extremely slow speed makes them impractical to use in offensive raids. However, prepositioning tortoises by restricting their area to chokepoints can sometimes be quite helpful when defending.
