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 Leedsichthys 

was a genus of gigantic pachycormid fish that lived in the oceans of the Mesozoic. Largely considered to be one of the largest bony fish to ever live, this behemoth could grow up to 32 feet long (some estimates put it at 53 feet). This giant fish although it had alot of teeth was probably a gentle filter feeder like extant basking sharks. leedsichthys had no recorded predator with specimens known to escape the Liopleurodon which was the top predator of the time, their large and powerful tail probably helped them out run and out maneuver the giant reptile.
