  The ANTARES detector is a Cherenkov underwater neutrino telescope operating
in the Mediterranean Sea. Its construction was completed in 2008. Even though
optimised for the search of cosmic neutrinos, this telescope is also sensitive
to nuclearites (massive nuggets of strange quark matter) trough the black body
radiation emitted along their path. We discuss here the possible detection of
non-relativistic down-going nuclearites with the ANTARES telescope and present
the results of an analysis using data collected from 2009 till 2017.
