Eubranchus inabai

Baba, 1964


Deb Aston This one found by my buddy Patrik today at the Seaway, 10mm. Anyone know what it is?

Matthias Wildermuth So what is the id now? Sure gary or ash would know!!

Deb Aston Waiting to hear back from Dr Richard Willan, will post as soon as I know.

Gary Cobb Richard says...The photo (IMG 2333) stopped my heart. It is certainly Eubranchus inabai (see http://www.seaslugforum.net/find/eubrinab) and this is the second record for Australia. Eubranchus inabai first arrived in Australia about the same time as Godiva quadricolor got here, certainly well before Spurilla neapolitana, but it was only ever found at the entrance to Wallis Lake, Tuncurry, New South Wales, in 1988. Because there have been no subsequent records, E. inabai was assumed to have died out in Australia. So this specimen from the Coolangatta seaway either represents a range extension or a reinvasion. Either way, it will be wonderfully exciting to know if it persists or vanished from there. Everyone must keep their eyes open for this distinctive little fellow.

Gary Cobb Hey Deb did you collect it?? Hummmm....you know the drill!

Patrik Good Thank you for the ID. Exciting and I think I will smile about it for a while: it was my first go at nudibranching and I have only seen about 20 different nudi species in my diving life. It is still Deb's merit that this one got documented and photographed.

Deb Aston Heh Gary didn't see it unfortunately so can't be held responsible for not collecting it. Will certainly go looking for more and take my squeezy bottle. Well done Patrik!
