Image Gallery: Stunning SEM images

by Jim Wetzel, USA

Editor's note:  Jim Wetzel kindly offered some striking images taken using a scanning electron microscope (SEM, model J.E.O.L.35cf). Jim writes:

'I use SEM as a teaching tool (my own research involves developmental
ultrastructure - specifically seahorses & pipefishes) and combine it with art to draw broader student interest (across disciplines) into biology as a field for everyone.'
