Hi, I'm Andrew and I’m just a simple 19 year old guy and zoology student that posts random factoids about obscure animals and general animal science/zoology/biology stuff so if you like animals this is the place for you, if you only like cute animals this is not the place for you… Also I can ID any animals you might need identified (just submit them to me).

Disclamer: none of the pictures are mine unless stated

Family Polioptilidae: A family of passerine birds commonly known as "Gnatcatchers". All gnatcatchers are native to the New World, being found in both North and South America. Gnatcatchers are close relatives of the wrens and some species are known as "Gnatwrens".

Order: Trigonotarbida

…an extinct group of arachnids that lived from the late Silurian to early Permian period. Trigonotarbids superficially resembled spiders but unlike spiders they have tergites on the dorsal side of their abdomen that are divided into median and lateral plates, they also lacked silk-spinning spinnerets. Trigonotarbids were a very diverse group of animals with most species found in the Carboniferous, although some were found in the late Silurian (415 mya), making them some of the first terrestrial animals. And as such they were very important in early ecosystems.
