Kentrodoris rubescens from Papua New Guinea

December 12, 2001
From: Mary Jane Adams


Hi Bill,
This is the first Kentrodoris rubescens I have ever seen in Papua
New Guinea. Is was crawling over the lagoon side of Horseshoe Reef, Bootless Bay at a depth of 5 meters. It seems appropriate that this weird looking beast showed up on Halloween.

Divesite: Wreck of the Pai II, Bootless Bay
Length: about 18-20 cm.

Dear Mary Jane,
From Tim Murrell's message it looks like K. rubescens has been in Bootless Bay for at least 6 months. Until your messages, I would have suggested, from my experience, that Kentrodoris rubescens was a spasmodic visitor rather than a permanent resident. I have only seen it alive a few times, the first time was in Tanzania, where I came across a very large population in a relatively shallow reefal lagoon with mixed sand, sea grass and coral heads. Most were large animals and there were many egg ribbons. In a month they had all gone. That is the only time I have seen more than two at a time.
Very interesting,
Best wishes,
Bill Rudman
