Rhi´no`phore


n.1.(Zool.) One of the two tentacle-like organs on the back of the head or neck of a nudibranch or tectibranch mollusk. They are usually retractile, and often transversely furrowed or plicate, and are regarded as olfactory organs. Called also dorsal tentacles. See Illust. under Pygobranchia, and Opisthobranchia.

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.
