Internal primers for 16S designed for another group of opisthobranchs (Ornelas-Gatdula et al.
The 16S gene is variable enough to distinguish among species of opisthobranchs and is even informative in population genetics studies (Krug et al.
Morphogenesis at metamorphosis in opisthobranch molluscs.
Developmental mode in opisthobranch molluscs from the northeast Pacific Ocean: feeding in a sea of plenty* Can.
Chemical diversity in opisthobranch mollusks from scarcely investigated Indo-Pacific areas.

New distributional records of opisthobranchs
from the Punta Eugenia region of the Baja California peninsula: a report based on 1997-1998 CONABIO-sponsored expeditions.
Only in the prosobranch Lunatia triseriata (Joseph 1982) and in the polar pelagic opisthobranchs Clione limacina, Limacina helicina and Spongiobranchaea australis (Phleger et al.
In the present study, the level of 20:4n-6 was below that found in these prosobranchs but was higher than that reported for polar opisthobranchs (Phleger et al.
However, most previous studies have been done in the opisthobranch and pulmonate species, the higher gastropods.
The sizes of both serotonergic and FMRF-amidergic neurons are different from those in other gastropods, especially in a pulmonate and opisthobranch molluscs, also in which the positive neurons showed remarkable size range (Fickbohm et al.
Aplysia dactylomela is a large marine opisthobranch
gastropod which inhabits shallow tropical shoreline regions, eats red and green algae, and lays large numbers of fertilized eggs in string-like gelatinous masses close to the sea surface.
