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.

Giant Siponophore 

(Praya dubia)

is a large species of  deep sea colonial hydrozoan of the family Prayidae. Found in  extremely deep South Atlantic waters. Their name of giant holds up as the are one of the largest invertebrates alive to day growing up to 160 ft long! (rivaled only by the bootlace worm at 180ft). This animal has a long string of small circle-like bells which make up most of the body, these are the stinging cells that are a trademark of cnidarians, a sting from P.dubia will cause paralysis or death. At the front? of the animal is a dome like bell which houses the animals nectosome (swimming bells). they like their Man o war relatives are hunters and use a blue bioluminescence to attract prey which it then kills with its stinging cells. Don’t expect to see one of these animals anywhere other than 2-3000 ft down as their hydrostatic skeleton will burst if brought to the surface.
