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".

Genus Sarotrocercus
Is a genus of small animals discovered on the Burgess Shale. They have a segmented body with nine segments and as such they are classified as a an arthropod.they also have two big stalked eyes and 20 comb like appendages on their underside which i can only assume were for swimming (kind of like a horseshoe crab not not the same). as you might of guessed from the picture the animal swam upside down, and were one of the few Burgess Shale animals that swam freely.
