Concerning message #22574:

Hi Bill,

Those are indeed the eggs of Phyllaplysia taylori in Ken-ichi's image. They match what I have observed on Zostera in Morro Bay, CA and also match the written descriptions of Bertsch & Hirshberg (1973) and Bridges (1975) of the egg mass of this species. The eggs do not appear as dense as those of the more southerly P. padinae because they are much larger and develop directly into juveniles, while those of P. padinae develop into much smaller, planktotrophic veliger larvae.

  • Bertsch, H. and J. Hirshberg. 1973. Notes on the veliger of the opisthobranch Phyllaplysia taylori. The Tabulata (Santa Barbara Malacological Society), 6: 3-5.
  • Bridges, C. B. 1975. Larval development of Phyllaplysia taylori Dall, with a discussion of development in the Anaspidea (Opisthobranchia: Anaspidea). Ophelia 14: 161-184.

Best wishes,
