Whilst there are major concerns about the spread of urchin barrens – and rightly so – it is possible for kelp and urchins to achieve a healthy balance in a system with adequate urchin predators.

Colourful sessile animals like these yellow zoanthids are a feature of Australia’s Great Southern Reef. The colours of the mature male blue throat wrasse aren’t too shabby either. Bicheno, Tasmania

#GSRfieldtrip day 35. Mt Wellington watches over two of our survey sites in Hobart. For the last few days it’s been clear, but today the clouds and drizzle moved in. #UNSWbees #scicomm
