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 Callidulidae: An unusual family of moths known as "Old World Butterfly-moths. Callidulids are a family of butterfly like moths which are distributed throughout southeast Asia and Oceania. Callidulids can exhibit both day and night flying behavior and typically hold their wings over thier backs like butterflies. Thier closest relatives are know truly known but they are thought to be close to hook-tip and geometer moths.

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.
