Tambja verconis from Port Stephens

From: Leanne & David Atkinson

Dear Bill,
We have found what we think is Tambja verconis. It is the first time we have seen it in the area over the last 20 years. Over the past month we have found three of them. One was at Fly Point and two were at Halifax Sponge Gardens. We have seen one at Halifax consistently in the same area over 4 dives spread over a month.

There were Tambja sp.1 in the same area. They were all on the Bugula dentata.

Dear Leanne & David,
This is Tambja verconis. It seems to be more regularly found further south, but at times it can be found as for north as Port Stephens. We have still a lot to learn about these animals. It would be interesting to know whether the bright blue pigment of this species is derived from their food. Your photos show how similar the colour of Bugula dentata can be to the blue of T. verconis.
Best wishes
