Pteraeolidia ianthina with eggs

April 5, 2003
From: Leanne & David Atkinson

Dear Bill,
After seeing Mary Jane Adams shots of Pteraeolidia ianthina mating we checked out the rest of the Pteraeolidia ianthina pages on the site. In your message with Akos' photo with eggs you talked about them laying on boulders and guarding the eggs. We recently photographed this one with eggs on a common plant/algae. Sorry about the quality of the photo, it was surgy with a sandy bottom and poor viz. The plant was swaying badly even when held. We tried hard not to disturb her/him. It was well wrapped around the eggs and difficult to get a clear shot.

Fly Point, Port Stephens, NSW, Australia
Depth: 8 meters. 11 January 2003
Time: 15.23, high tide 1.22m
Temp: 21 degrees C.

Thanks Leanne & David,
I've included 3 versions of your photo to show the egg ribbon in detail and the rather unusual flattened looking cerata. This species seems to be quite variable both in shape and length of the cerata.
Best wishes,
Bill Rudman
