This is one of the biggst slugs I have seen, about 4 inches (10cm) in length.
Slugs and snails are hermaphrodites, which means they have both male and female sex organs. They lay their eggs in masses of up to 100 eggs in soil, under debris, rocks and plants. The eggs are large, 1/8 to 1/4 inch in diameter, and are white or colourless.The eggs take from two to four weeks to hatch but will not do so unless their is moisture present.
