quoting perldoc perlvar
@ARG
@_

Within a subroutine the array @_ contains the parameters passed to that subroutine. Inside a subroutine, @_ is the default array for the array operators push, pop, shift, and unshift.

See perlsub.
Example:
Code:
my($one, $three, $five) = (1, 3, 5);

print_values($one, $three, $five);

sub print_values {
    my(@values) = @_;    # subroutine argument list

    foreach my $val (@values) {
        print "${val}\n";
    }
}
