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.

Sloane’s Viperfish (Chauliodus sloani)

…is a species of dragonfish/viperfish found in most subtropical and tropical oceans worldwide. Like most viperfish this species is normally found in deep waters at around 8,000 ft deep. They are most noted for their impressive teeth which are the largest teeth in the animal kingdom relative to head size. The fish uses these spear-like teeth to impale its prey in a quick dash. To withstand the shock in this the viperfish has a vertebrae behind its head which acts as a shock absorber.
