Often I read about species like peregrine falcons that are said to be found on every continent except Antarctica. That just makes me wonder whether there are any species (bacteria, etc; terrestrial, or aquatic if it counts) truly found on every continent, including Antarctica. Of course, humans are…

When it comes to fungi then I think care is needed in interpreting the evidence. Current phylogenetic data indicate at least 3 distinct taxa under the name Galerina marginata. One appears to be distributed across Europe and the (eastern?) USA, another across Asia and (western?) USA and a third in Au…

I think it would be even more interesting to break it down to those that have breeding populations on every continent.

Tardigrades cheat though…they’re a phylum. Like vertebrates.

Polytrichum juniperinum, or Juniper Haircap Moss.

They do not naturally occur there.

There are over a thousand different species of tardigrade, though. They would only count if there was a single species of Tardigrade that is found everywhere, which I think is very doubtful.

There is at least one arachnid species found on every continent: Ixodes uriae. They are generalist ticks that parasitize a wide variety of seabirds that nest in colder regions, including penguins, auks, albatrosses, petrels, gulls, and more. They are found in the northern regions of the US, Canada, …

LOTS of foraminifera species have completely global distributions. Trochammina inflata, for example, is known from Antarctica ( https://www.sciencedirect.com/science/article/pii/S235248551830166X ), Australasia ( https://www.bing.com/search?q=new+zealand+shallow+water+benthic+foraminifera&cvid=0fb0d66…

I’m not sure about a single species, but the fly family Chironomidae are the only flies found on every continent, including Antarctica.

Well, there is only one higher plant species that can be found on all continents as far as I know: Poa annua This species is very interesting, it is an allotetraploid species resulting from the crossing of Poa infirma x Poa supina and can now be found all over the world, including Antarctica. http…
