Phidiana indica from Papua New Guinea

From: Marli Wakeling

Hi Bill,
Here is another nudibranch from Papua New Guinea. I did see this one quite frequently in shallower areas. This was found on Albatross Channel, home of the famous Pygmy Sea Horses. I believe it is a Caloria indica.

Dive Site: Albatross Channel, near Kavieng, Papua New Guinea
Date: July, 2001
Depth: 15 metres
Length: 30 mm

Dear Marli,
This is Phidiana indica, Caloria being considered an unnecesary extra genus. As you'll nptoce from the other photos on the Forum this species tends to walk quite quickly in a straight line so most photos of it are long and thin. So that you can see some detail I have included a close-up of the head end as well.
Best wishes,
Bill Rudman
