Injection of GABA into the hemocoel of Clione
limacina, however, evoked elements of its complex predatory behavior, including tentacle protraction, mouth opening, and rhythmic movements of the buccal mass (Arshavsky et al., 1991, 1993).
Further species mentioned in the Discussion: Clione
vermifera Hancock, 1867, Pione carpenteri (Hancock, 1867), Siphonodictyon crypticum (Carballo et al., 2007).3 Total species counts are based on analyses without spicule preparations: Quadrat and intercept studies relate largely to preliminary species identifications in the field, while for all material foundin rubble quick pluck preparations were made.
DA contracts the somatic posture muscles in the pteropod mollusc Clione
limacina, whereas ergometrine relaxes these muscles (Salcharov and Kabotyansky, 1986).
The exception is the polar opisthobranch Clione
limacine, which has been reported to present a percentage of 17:0 up to 4% (Phleger et al.
GABAergie excitatory synapses and electrical coupling sustain prolonged discharges in the prey capture neural network of Clione
In gastropod embryos and adults, a similar expression pattern is restricted to the anterior, medio-dorsal parts of cerebral ganglia, as seen in the vetigastropod Haliotis (Barlow and Truman, 1992; Hinman et al, 2003), the caenogastropod Crepidula (Dickinson et al., 1999), and in many heterobranch species, e.g., Helisoma (Goldberg and Kater, 1989), Lymnaea (Croll and Chiasson, 1989), Aplysia (Dickinson et al., 2000), and Clione
(Slatternly et al., 1995), and even in cephalopods, e.g., Idiosepius and Octopus (Shigeno et al., unpubl.

Conover and Lalli (1972) kept the pteropod Clione
limacina "indefinitely" in small dishes and beakers with filtered water.
It has been described for at least 47 species (reviewed by Farmer, 1970), and the neural mechanisms underlying swimming have been investigated in detail in four of these: Pleurobranchaea californica (Jing and Gillette, 1995, 1999), Tritonia diomedea (Willows et al., 1973; Hume et al., 1982; Getting, 1983), Clione
limacina (Arshavsky et al., 1985; Satterlie, 1985, 1991; Satterlie and Spencer, 1985; Satterlie et al., 1985; Satterlie and Norekian, 1996), and Aplysia brasiliana (von der Porten et al., 1982; McPherson and Blankenship, 1991a,b).
