Koehler, E., 2002 (Apr 25) Spawn of Bulla ampulla?. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/6752Dear Erwin,
I think this is its egg mass. The egg masses of the Californian Bulla gouldiana are described as looking like this and Kilburn & Rippey (1982)describe the spawn of Bulla ampulla as:
"The spawn is a long, bright yellow to orange, tangled string of jelly, containing a continuous string of tiny oval capsules. Each one contains 1-25 eggs, which develop into free-swimming veliger larvae".
I can't recall actually seeing B. ampulla spawning and the spawn mass of the temperate Australasian species Bulla quoyi is a jelly-like sphere, rather than a long cylinder.
