23rd Nelson Bay Sea Slug Census Results

14-15th March 2020

➢ 35 participants in 18 teams submitted 252 photos of 60 different species!

➢ Slugs were hard to find! This census had the lowest March species count

(60), 8 less than the previous lowest March count in 2014 (68), and 32

less than the amazing census in March 2016 (92).

➢ Incredibly, despite the general lack of slugs, 2 new species were found.
