I Want To See Tularia Again

When you ask about nudibranchs living in New Zealand, the usual answer mentions Dorises like black, lemon or gem, then clowns, perhaps Jasons and Tambjas. I was so surprised when I was diving in silty Mahurangi Harbour and found a flat reef with these nudibranchs crawling on brown weeds. They were everywhere, a couple of them on each plant. They looked like they were carrying torches of flame on their backs. Some time later I found out they were Tularia bractea nudibranchs. But I have never seen them since, and would love to.
