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".

Jellyfish eyes
more than just water and goo
Most people think of jellyfish as primitive floating balls of jelly and water that aren’t good at anything but stinging people. And while it is true that most jellyfish aren’t exactly “advanced” as far as animals go one class of jellies takes it to the next level. Box Jellies or Sea Wasps are cnidarians of the class cubozoa. Named after their umbrella shaped medusae these small jellies are the one of the most venomous animals in the world. They are also the most developed as they sport a nerve ring and 24 sets of eyes which are located at the base of the bell. Most of these eyes do simple tasks like distinguished between light and dark. But amazingly they also have eight pairs of highly developed, almost human like, eyes which can detect the size and color of different objects. With these eyes the jellyfish can not only navigate its ocean environment with ease but it can also detect and avoid different obstacles.
