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.

Cannonball Jellyfish (Stomolophus meleagris)

Also known as the cabbage head jellyfish, the cannonball jellyfish is a species of jellyfish found from the eastern seaboard of North America all the way down to Brazil, with some populations found throughout the Pacific as well. Like other jellyfish the cannonball feeds mostly on zooplankton that it dispatches with its stinging nematocysts. The Cannonball also has a symbiotic relationship with L.dubia the Longnose Spider Crab (and a few fish/crab species)which resides on the jelly and feeds on passing zooplankton and sometimes the jelly itself. Like all jellyfish the cannonball jellyfish does sting and can cause immense pain in humans,  it also has a mucus that it releases though its nematocysts as well, this mucus has a toxin that when released harms animals in the immediate area. This is used to stun prey and drive away predators and can be dangerous for humans as it can cause cardiac problems.
