Ever wanted to swim with a sea slug?
Nudibranchs are a type of sea slug that have no shell. We have about 130 species in New Zealand, 60 of which are only found here.
We go snorkelling around Tāmaki Makaurau with marine conservation expert Lorna Doogan to see what they are.
This story is part of Re:'s Oceans Week, where we talk rāhui, diving, sunblock and more. See the rest of our Oceans Week stories here.
