		| Abstract: | I discuss our current understanding of the nature of high-redshift (z > 2)
 (sub)-millimetre-selected galaxies, with a particular focus on whether their
 properties are representative of, or dramatically different from those
 displayed by the general star-forming galaxy population at these epochs.
 As a specific case study,
 I present some new results on the one sub-millimetre galaxy which happens
 to lie within the Hubble Ultra Deep Field and thus benefits from the very
 best available ultra-deep optical-infrared
 Hubble Space Telescope  and Spitzer Space Telescope imaging.
 I then consider what these and other recent results from optical-infrared
 studies of sub-millimetre and millimetre selected galaxies
 imply about their typical
 masses, sizes and specific star-formation rates,
 and how these compare with those of other star-forming galaxies selected
 at similar redshifts.
 I conclude with a brief discussion of the continued importance and
 promise of SCUBA2 in the era of Herschel. |
