Turtles in World of Warcraft are similar in appearance, but much greater in size than their real-life counterparts. They can be found both on land and in water.
Turtles of different species are found all over Azeroth. One of the most famous species is the giant sea turtles used by the goblins during the Second War. They were originally believed to be native only to the South Seas but have also been discovered in Northrend.
The most important distinction between the different kinds of turtles is which drop Turtle Scales and which do not. In general, turtles of a higher level have a better chance of dropping Turtle Scales. The turtles in Dustwallow Marsh rarely drop scales, while the ones in Tanaris may drop two or three at a time. The turtles in Thousand Needles never drop scales. Farming Turtle Scales is the primary reason to kill a turtle.
Tortoises (land turtles) are pretty much interchangeable with turtles in the game, since they all look the same. You can assume it is a tortoise if it doesn't appear near a large body of water (lake, river, or sea).
Some turtles can grow to enormous sizes. During the Second War, the orcs used them as submersible war machines. Their shells were so large that several orcs could fit inside them, and they attached goblin-made rockets to the top of their shells.
The goblins themselves also seem to have taken up turtles as a mount; a pair of mounted goblins can be seen on turtles in Booty Bay. With the recent discovery of Pandaria, it has been revealed that the pandaren also use dragon turtles as mounts.
Turtles make for notably sturdy tanking pets with their special ability Shell Shield, which reduces damage taken by 50% for 12 seconds.
Though hunters can respec their pet turtles into Cunning or Ferocity, they are inherently Tenacity. In addition to the abilities that come standard with all pets ([Cower], [Growl], [Avoidance]) and those given to their natural or retrained specialization, all turtles are given the following:
A few turtles may actually be mobs that have been polymorphed. Beware of any unusual turtles in unexpected locations!
