Can someone help me to understand the behavior of the following code? Im unable to find this documented. 
#!/usr/bin/perl -w

use strict;

my %animals=( 'cow'   => "bessie",
              'horse' => "ed",
              'duck'  => "goose",
              'dog'   => "rexx"
            );

print "my animals\n";
print_hash();

my $ranimals=\%animals;
$$ranimals{'duck'} = "franklin";

print "\nmy referenced animals\n";
print_hash();

sub print_hash
{
    for ( sort keys(%animals) )
    {
        print "$_ = $animals{$_}\n";
    }
}

when I change $$ranimals{'duck'} to shouldnt $animals{'duck'} still be "goose"? Or am I just greatly misunderstanding what this is doing?

Update
after typing this out I think Im seeing the error of my ways. Im going to leave the question stand though. My original intention was to review a lot of the code ive written over the years and bring my code more into line with my understanding of perl now. Ive recently read a few books such as "Effective Perl Programming" and "Advanced Perl Programming" and am trying to bring my skills to a higher level. I think I need to have another go-round with perlref.
