statocyst of Lymnaea stagnalis," Journal of Neurophysiology, vol.
The squid make use of two narrowly spaced organs called
statocysts to sense sound.
Other researchers in Alkon's lab have detected GABA in the tiny, hair-bearing cells of
statocysts -- organs used by H.
11A): Peduncle three-segmented, 1st segment with one large ventral spine, one small proximal spine, 40 plumose setae and a
statocyst, 2nd segment with 10 plumose setae, 3rd segment with seven plumose setae; outer ramus two-segmented with 2, 6 aesthetascs; inner ramus two-segmented with 1, 3 plumose setae.
Metamorphosis occurs after the pediveliger stage, when the velum is lost, the mantle forms, and the
statocyst and dark bodies appear, among other morphological changes (Jameson, 1976; Fitt and Trench, 1981; Neo et al., 2011).
The antennular
statocyst that appears during larval stage VII of the giant river prawn has an array of sensory structures that enable the perception of chemical and tactile stimuli beginning with its early life stages.
The four lamellate body groups lie on either side of the sagittal plane, in two pairs extending from opposite sides of the central
statocyst (Figs.
Such biomineralized structures are observed in multiple invertebrates, including gastropods (
statocyst and protoconch), cephalopods (
statocyst), and bivalves (prodissoconch) (Zacherl et al.
Aplysia californica has been shown to have strong control of tissue pH, utilizing carbonic anhydrase and urease to tightly control acid-base balance and thus aragonite deposition in the
statocyst (Pedrozo et al., 1997).
The appearance of larval structures, such as the velum,
statocyst, left and right digestive diverticula, eyespots, and propodium was recorded.
Ctenophores, or comb jellies, are geotactic with a
statocyst that controls the activity of the eight ciliary comb rows.

statocyst: insights into the antiquity of metazoan geosensory organs.
