Our Changing World: The thorny issue of the long-spined sea urchin A native urchin species is grazing the Poor Knights Islands down to bare rock. But what can be done?

Great read - if worrying. I used to do most of my diving at the #PoorKnights - best diving in NZ. Good to see #kina under control but awful for these other critters to get out of hand.

Thread. Most of my diving was done at the #PoorKnights. Warm currents meandering across from Aus see more tropical sea life there than around the main land. Gorgeous.🐟🐬
