Obscure Animal Of The Week #2: Triops


Triops.
Triops, also known as tadpole shrimp, are a small form of crustacean. They have a shell which offers some rudimentary defense against some predators. Some triops have been found with up to 140 legs. They typically crawl around on the seafloor or swim short distances using their tails.
Triops have three eyes, two "normal" ones and one that is used to detect light. However, they don't use their eyes to fnd prey. Instead, they use a sense similar to smell, except they use their legs to smell, which is pretty fucked up.
In the northern hemisphere, there are very few male triops; in some places, there are only females. Fortunately, triops don't need their eggs to be fertilized. In the southern hemisphere, the numbers are more even. Triop mating has only been observed twice, by some very perverted scientists.
The eggs are absurdly resilient, able to last nine years in conditions such as drought, strong winds, temperatures from freezing to 80 degrees Celcius, and even the digestive system of a frog.
They eat small shit. You know, plankton, worms, assorted larvae, etc.
They tend to live for somewhere between two weeks and three months.
Evolutionarily, triops have remained essentially the same since the Triassic period, making them the oldest known living animal.
So there you go.
The source is, of course, Wikipedia.
