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.

Marsupial Lion (Thylacoleo carnifex)

…a extinct species of diprotodont marsupial that lived in Australia from the early to the late Pleistocene. Like actual lions T.carnifex was probably an ambush predator and fed on megafauna like Procoptodon and Sthenurus. However it was not an apex predator as it shared a range with the 20ft long goanna Megalania. The marsupial lion was a highly specialized predator as it possessed unique teeth that were similar to canines, they also had huge blade-like premolars on either side of their jaws. This combined with exceptionally large jaw muscles gave the marsupial lion an extremely powerful bite. A 100kg individual would have a bite comparable to a 250kg African lion and it could kill a large animal in less than a minute compared to a lion which would take 15 minutes to kill a large catch.
