Welcome to the wonderfully weird world of The real aliens among us
This little fella lives among us all. We sleep with him every night. We breathe him in, he eats our skin. He is a dust mite, so tiny he is invisible to the naked eye. The brown lumps next to him are human skin - we shed 8 lbs of skin each year so plenty food for the little darlings. The blue strips are minuscule clothing fibres containing a blue dye, likely from your favourite blue outfit. Some people's bodies don't like dust mites, they are usually asthmatic. The mites like to live in your pillow and your duvet and right now there are millions of them in your bed, keeping it clean by eating your dead dry skin and hair.
It is said this alien can manifest in your food if left out to spoil - the magnificent massive maggot (in this image). This larvae of a bluebottle fly is particularly evil looking however those sharp teeth can come in handy for us in the form of maggot therapy also known as maggot debridement therapy (debridement meaning wound). It is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into the non-healing skin and soft tissue wounds of a human or animal for the purpose of cleaning out the necrotic (dead) tissue within a wound and disinfection. However the little darlings also cause humans problems when spreading microbial infections, and causing myiasis.
It's the Yeti Lobster! Also known as the Yeti Crab or by its traditional name, Kiwa Hirsuta. This Yeti inspired beast was only discovered in 2005 near Easter Island and is thought to be blind, poor critter. However it was blessed with a rather kingly title - Hairy Guardian of the Sea. Kiwa in Māori mythology means "male guardian of the sea" and Hirsuta means "hairy" in Latin.
Aliens in the deep deep blue
This spiral of tiny aliens is actually a sea snot eating angel. It is a formation of several mini aliens also known as Sea Salps, nature's deep sea cleansing creatures. They feed on sea snot, a substance created by stressed out phytoplankton. They eat the gunk that pollutes our sick seas (thanks to the humans) and then safely turn it into carbon and lock it into the bottom of the ocean floor. Spring cleaning the planet while we sleep. Angels.
