SummaryMany cephalopods have lines of ciliated cells on their head and arms. In the cuttlefishSepia and the squidLolliguncula, electrophysiological recordings clearly identify these epidermal lines as an invertebrate analogue to the mechanoreceptive lateral lines of fish and aquatic amphibians and thus as another example of convergent evolution between a sophisticated cephalopod and vertebrate sensory system. Stimulation of the epidermal lines with local water displacements, generated by a… 
Behavioural responses of juvenile cuttlefish (Sepia officinalis) to local water movements
Results indicate that cuttlefish can detect local water movements and are able to integrate that information into behavioural responses and are most likely with the epidermal head and arm lines.
A critical period of susceptibility to sound in the sensory cells of cephalopod hatchlings.
Evidence of acoustic trauma in cephalopod hatchling sensory cells after sound exposure is provided, whose damage increases faster than in adults, suggesting a critical period of sensitivity to anthropogenic noise in early stages.
Peripheral and central nervous responses evoked by small water movements in a cephalopod
Evoked potentials can be recorded from the brain while stimulating the epidermal lines with weak water movements and show little or no onset or offset wave at the transitions of a frequency and amplitude modulation.
The evolution of scale sensilla in the transition from land to sea in elapid snakes
Assessment of morphological variation in sensilla on the postocular head scale(s) across four terrestrial, 13 fully aquatic and two semi-aquatic species of elapids represents the first analysis of the evolution of sensilla in the transition from terrestrial to marine habitats.
Novel, secondary sensory cell organ in ascidians: In search of the ancestor of the vertebrate lateral line
It is proposed that the coronal organ in urochordates is homologous to the vertebrate acoustico‐lateralis system.
Evolution of Polarized Hair Cells in Aquatic Vertebrates and Their Connection to Directionally Sensitive Neurons
It is suggested that this cell evolved, through morphological intermediates, which transformed the kinocilium surrounded by microvilli of the unicellular ancestor of metazoans into the polarized stereocilia of vertebrate hair cells, suggesting an evolutionary progression through multiplication of genes of the mechanosensory hair cell followed by cellular and organ diversification.
The Biophysics of the Fish Lateral Line
The fish lateral line system is unique in its ability to sense water flow with two types of receptors, the canal neuromast (CN) and superficial neuromasts (SN), which encompass distinct regimes of stimulus intensity and frequency.
Ultrastructural evidence of a mechanosensory function of scale organs (sensilla) in sea snakes (Hydrophiinae)
It is concluded that the scale organs of marine hydrophiines have retained a mechanosensory function, but future studies are needed to examine whether they are sensitive to hydrodynamic stimuli.
Mechanosensitivity in the model sea anemone Nematostella vectensis
NANA shifts vibration dependent discharge of basitrich nematocysts to lower frequencies overlapping those produced during swimming by known prey including planktonic crustaceans, and it is found for the first time that vibration detection extends at least 2.5 cm beyond the tentacle tips.
The sensory epithelium of the tentacles and the rhinophore of Nautilus pompilius L. (cephalopoda, nautiloidea)
Nine intraepithelial ciliated cell types that are presumed to be sensory cells were identified in the epithelium of the pre‐ and postocular tentacles, the digital tentacles, and the rhinophore of the


Lateral Line System
The lateral line system consists of water-movement-sensitive sensory organs in the epidermis of cyclostomes, fishes, and aquatic stages of all three orders of amphibians, and derives from dorsolateral placodes.

The statocyst of octopods is a sack containing endolymph, lying in a larger cavity, containing perilymph and crossed by strands containing blood vessels. The arrangement shows remarkable parallels
Mechanical Factors in the Excitation of the Lateral Lines of Fishes
The effective stimulus to a neuromast lying inside a typical lateral line system will be one that produces a movement of the cupula of the neuromast relative to the wall of the lateral line canal.
Extracellular Receptor Potentials from the Lateral-Line Organ of Xenopus Laevis
It is concluded that under conditions of stimulation with small-amplitude water movements, the hair cells respond to sensory hair displacement, whereas under conditionsof stimulation with large-am Plinian water movements they respond to sensations of sensory hair velocity.
Why Cephalopods are Probably Not "Deaf"
Some behavioral information is added that, in contrast to Moynihan's hypothesis, indicates that cephalopods can perceive underwater vibrations.
The Angular Acceleration Receptor System of the Statocyst of Octopus vulgaris: Morphometry, Ultrastructure, and Neuronal and Synaptic Organization
The angular acceleration receptor system (crista/cupula system) of the statocyst of Octopus vulgaris has been thoroughly reinvestigated, and detailed information is presented regarding its
Lateral-line responses to water surface waves in the clawed frog,Xenopus laevis
The responses of free-standing lateral-line organs to water surface waves were examined in the clawed frog by recording from the organs' afferent fibers, and an asymmetry between the inhibitory and excitatory transduction processes is demonstrated.
The lateral line mechanoreceptive mesencephalic, diencephalic, and telencephalic regions in the thornback ray,Platyrhinoidis triseriata (Elasmobranchii)
Central lateral line pathways were mapped in the thornback ray by analyzing depth profiles of averaged evoked potentials (AEPs), multiunit activity (MUA), and single unit recordings.
Selective and Reversible Blocking of the Lateral Line in Freshwater Fish
It is shown that cobalt ions in the external water may completely block the mechanosensitivity of the lateral line without affecting the utricular microphonic activity, and that recovery was dependent upon both the duration of the Co 2+ exposure and the Ca 2+ concentration of the recovery solution.
The structuredre and ultrastructure of the neuromast is described, as well as the growth of cupulae and other structures, are described.
