i found another specimen of a super rare organism yesterday!
this is a rare and remarkable ciliate, a single-celled organism called Metopus verrucosus.
a few neat facts about it:
it’s an anaerobic organism! this means it prefers to live without oxygen
it lives deep in the mud of sulfur- & methane-rich bodies of saltwater. this one was found in the salt marsh estuary on the side of the garden state pkwy in south New Jersey!
it couldn’t survive in these noxious conditions by itself, though! the fuzzyness covering it’s cell is actually a type of bacteria that symbiotically lives on M. verrucosus.
this bacteria has the ability to metabolize sulfur and/or methane, processing these volatile stinky chemicals and turning it into energy, that it then shares with M. verrucosus!
i’m the only known person with this kind of footage of M. verrucosus! the paper The Santa Barbara Basin is an Oasis of Symbiosis has the only other photo i’ve seen of this organism, and it’s actually an HVEM (electron microscope) photo of a cross-section of the cell showing it’s endosymbiotic bacteria.
here are some more photos i took of other specimens:
when i was checking on my recent personal post tumblr recommended another one from months ago when i was posting about a didinium ingesting a paramecium for some reason? in a (to me) quite disturbing illustration. any way here's a more disturbing illustration of didinium ingesting a paramecium
One of the biggest single-celled creatures. It is fixed to an alguae when it doesn't swim, and adopt a trumpet-like shape. It can contract itself (I've seen some of them completely vanish when they decide to contract behind an alguae). Its "mouth" is equipped with ring of cilia, which perform a speed rotational movement to aspire water and even your soul (you can clearly see this one absorbing a small organic detritus).
