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".

Electric Ray Defense Ball
a shocking defense mechanism
Several species of electric rays have learned to use their electric organs not only to stun their prey but also for defense. When threatened the ray will curl up into a ring like position with its belly facing the predator presenting the potential predator with the area of its body that can deliver the most powerful shock (the underside of its electric organs), this only happens if the ray is touched on the tail. if the ray is touched on its disc it will simply turn toward its assailant and attempt to shock it, and then quickly attempt to flee. These shocks are usually dealt as short and strong bursts, the frequency of the bursts depends on what the ray is defending as it will produce more bursts if it was attempting to protect its tail than if it were trying to protect its disc.
