A worm found living very deep down

Three kilometers beneath Earth’s crust, in a realm known as the subsurface, temperatures in the thick rock are well over 40°C, and the oxygen-poor water chokes out familiar life. Here, slow-growing bacteria and other microbes flourish in masses called biofilms. It has now been discovered that a ravenous predator also survives in these hellish conditions: a roundworm that researchers describe today as the first multicellular organism to be found in the deep subsurface of Earth.

The 0.5-millimetre-long H. mephisto, named in reference to the light-hating demon of the underworld, feeds on films of bacteria that grow more than a kilometre down within the warm walls of the Beatrix gold mine, located some 240 kilometres southwest of Johannesburg.

    Superb blog! Do you have any suggestions for aspiring writers?
    I’m planning to start my own site soon but I’m a little lost on everything.
    Would you propose starting with a free platform like WordPress or go for a paid option? There are so many

    ideas? Kudos!
