Ercolania margaritae from Victoria

From: Joan Hales

Dear Bill,
Here are some photos of Ercolania margaritae. This was an accidental collection from Walkerville [southeastern Victoria, Australia]). It was not sighted until 19 days after collection when it was about 7mm in length. It was feeding on the Chaetomorpha weed, which I had collected to identify. After one week I rephotographed the specimen. It had grown amazingly in that week, doubling in length and seemingly adding many new cerata. The two photos are both to the same scale.

Thanks Joan,
The growth information is certainly very interesting. Concernng its identity. It certainly matches the illustrations I have rcently posted of Burn's E. margaritae. What we need to know now is whether this is the same as the species I have on the Forum as Ercolania boodleae. An intersting little project for someone.
Cheers,
Bill Rudman
