5-trisphosphate receptor in Aplysia californica rhinophore
The middle part of each rhinophore
is light yellow with black spots; a number of minute brownish spots is located at the base of each rhinophore
The pulmonate mollusks have 2 pairs of tentacles: the superior and inferior tentacles, and the anterior and posterior tentacles, which are called the cephalic tentacle and rhinophore
(Beesley et al.
The juveniles of this species exited their shells while leaving the egg capsules, and one day after hatching had rhinophore
buds and an oval notum reinforced by calcareous spicules and edged with secretory glands (Figure 1B & C).
There is a extra-branchial appendage situated alongside each rhinophore
and an extrabranchial appendage on each side of the gill.
Cerata and rhinophore
primordia developed by day 6.
d) Green cerata with yellow subapical band; black rhinophore
tip: yellow median line on the anterior part of the head.
A ciliated sperm groove is present on the right side of all specimens and runs longitudinally from a region between the rhinophore
and oral tentacle to the visceral sac (Fig.
Our prior studies have shown that an initial stimulus induces an hour-long short-term sensitization, involving the enhancement of several features of the animal's escape response, including increased swim cycle number, reduced swim onset latency (see below), decreased threshold, and reduced gill and rhinophore
withdrawal latencies (Frost et al.
nerve with seawater that had bathed A.
The behaviors are distinguished by characteristic body postures involving the oral hood, the rhinophore
processes, and the cerata, as well as by the presence or absence of pedal locomotion.
Green and Gosliner (2016) presented molecular genetic evidence that specimens of a previously unidentified Flabellina with smooth to slightly wrinkled rhinophores
and a notum irregularly covered with opaque white pigment collected by JG from Tarpits Reef, Santa Barbara County (CASIZ 195988) and Coleman Beach, Sonoma County (CASIZ 195990) are identical to F.
