Yup - quite nonrectangular - the initial images will look somewhat like this - although larger and more diverse (and if ya wanna know what all of that stuff is, msg me and I'll be happy to talk about it)- and I would like to be able to select and cut out the portion of the photo that pertain to each species, dump them in a seperate file (I was thinking transparent gif or png, so the only pixels are those that are from the species), then I'd like to run a script that counts the total number of pixels taken up by the selection.

So, in really ugly psuedocode
my $referencepixels=countpixels($referencefile);
@data=ls($datadir)
foreach my $file (@data){
  my $cover=countpixels($file)/$referencepixels;
  $datahash{$file}=$cover;
}
output_to_datafile(%datahash);
