Thanks Erwin,
It is interesting to see the bifurcating tips to the parapodial lobes. I can't find any mention in the literature of such a character so it may be something unusual in this specimen.

I see it is on the introduced Caulerpa taxifolia. In a recently published paper it says that Lobiger serradifalci, which naturally feeds on Caulerpa prolifera, has begun to settle and feed on C. taxifolia. However, rather than helping to control the spread of this introduced algae it may in fact be hastening its spread. In the Mediterranean, at least, C. taxifolia is reproducing vegetatively, by small pieces breaking off and growing into new plants. Unfortunately, Lobiger serradifalci feeds by piercing holes in the cell wall, which weakens the plant and allows pieces to break off, so hastening the spread of the algae. Unfortunately nothing is simple!

Best wishes,

Lobiger serradifalci from the Mediterranean

November 9, 2001
From: Bill Rudman

As background for the on-going discussion on Lobiger viridis here is some information on the Mediterranean species Lobiger serradifalci (Calcara, 1840).

Thompson (1988) gives a full description of this species. The parapodial flaps do not have secondary branches or crenulations along the edge of the flaps. There is a notch at tip of radular teeth, and Thompson describes "thorn-like lateral denticles" on the smaller teeth.. These are lost in the larger, more recent teeth.
