Jason mirabilis from New Zealand

January 8, 2004
From: Mark Burnett


Hi again Bill and Happy New Year to you. Following up on my message of last June, I dived on the Rainbow Warrior again on 17th December and found two small and one large Jason mirabilis plus quite a few egg ribbons. The small specimens were both around 3cm and the large one 5cm. Hopefully I will be back at the Warrior later in January so will have a chance to see if there is an increase in their numbers.
These pictures were taken at a depth of 23 metres and water temperature was 16 degrees Centigrade.

There are now large numbers of Tambja verconis on the abundant Bugula dentata and I also found yet another colour variation of Dendrodoris denisoni which I have attached in a separate message .

Best regards

Thanks Mark,
It's good to see some good come of the bombing of the Rainbow Warrior. The artificial reef it has become has certainly attarcted a lot of interest in the marine enironment. Jason mirabilis seems to have become either a permament resident or a very regular visitor. I was interested in your mention of the large populations of Tambja verconis. I guess it would be hard to miss, but it might be worth looking out for Roboastra luteolineata. If you are very lucky you might see it feeding on Tambja as reported by the Armstrongs [see message].

Best wishes
