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 Cassiopea 

(upside-down jellyfish)

Genus cassiopea is a genus of jellyfish  commonly known as Upside-down jellyfish found in coastal regions around the world in mangroves, mudflats and turtle grass. they earned the name upside-down jellyfish due to the Medusa stage usually lives upside down with the tentacles in the “air” and the bell on the bottom like a sea anemone, they then sit on the floor and feed. their sting is relatively mild as the animals are primarily photosynthetic. they have a symbiotic relationship with the urchin crab (Dorippe frascone) who picks up the cnidarian and carries it on its back and the jellyfish defends the crab. the genus includes 8 species: C.andromeda,C.depressa,C.frondosa,C.medusa,C.mertensi,C.ndrosia,C.ornata,C.xamachana. people often think something is wrong with the animals as they sit on the bottom and just pulse but they are fine.
