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".

Spider-tailed Horned Viper (Pseudocerastes urarachnoides)

…a species of Persian horned viper collected in western Iran in 2006. Like its common name suggests this unique viper has an odd wind scorpion shaped growth at the tip of its tail. Originally it was thought to be a Persian Horned Viper (Pseudocerastes persicus) with a odd tumor, but it was later reveled that a whole population had these growths and they were named a new species. 

The growth is actually used as a lure and experiments have shown that birds who peck at it were lead to the vipers head and eaten. So far it has only been observed preying on birds but it is though to prey on other predators of wind scorpions as well.
