What extreme barrier have Triops cysts been known to survive passing through intact?
Answer
The digestive tracts of birds
The microscopic cyst stage, or egg, is the powerhouse behind the Triops' longevity, possessing incredible durability. This toughness is so pronounced that the protective shell structure allows the eggs to pass entirely intact through the digestive systems of animals, such as birds, that might consume water or mud from the temporary pond. This ability to survive gastric acid and transit through an animal before being deposited elsewhere further aids in dispersal, alongside their proven resistance to freezing and decades of complete drying out.
