coloured scanning electron microscopy by steve gschmeissner (and sixth photo by nicole ottawa). an electron microscope uses a particle beam of electrons, which have much shorter wavelenghts than photons (visible light) and produce a greatly magnified image of the illuminated specimen (up to 10 million times).
dyk: the tardigrade, or water bear, seen in the last photo, can survive in temperatures of one degree kelvin and tolerate pressures six times that of the deepest oceans. despite preferring simple ground dirt, these creatures (which aren’t technically extremophiles) were shown in one experiment to have survived ten days in the vacuum of space. they can also endure heavy doses of radiation and hibernate for a decade.
dy-also-k: the maggots of the bluebottle fly (the goofy looking dude in the first photo), are used medicinally to clean wounds. once sterilized, they are placed in a wound where they feed on dead tissue and leave healthy tissue untouched. their saliva contains anti bacterial chemicals which maintain sterility in the area.

OK, I’m just gonna say what I’m thinking here: TINY CONFUSED WALRUS.
