“…These results do not confirm that lls type is determined by the time of initiation of scales and trunk canal, previously assumed by Voronina (2009). Also, the assertion that lls reach the definitive structure early in ontogenesis (Voronina 2007) is correct only for species with the simplest structure as in H. platessoides with type bIII*.…”

“…The morphology of lateral line scales ( lls ) has been described for various teleost species, but until recently, there have not been any criteria to facilitate comparison between them. Three characters, namely degree of modification of scale plate, position of posterior opening and completeness of tubular part, provide universal criteria (Voronina 2007). Combination of their different states into 13 structural types explains a large amount of lls diversity, enabling lls comparison and classification in 179 species of flatfish families (Voronina 2009).…”

Voronina, E.P. and Hughes, D.R. 2011. Types and development pathways of lateral line scales in some teleost species. —Acta Zoologica (Stockholm) 00: 1–13. A comparative study of lateral line scales (lls) in nine teleost species was undertaken to trace their ontogenetic structural changes. Three universal characters were used to describe and classify definitive and developing lls. The four main structural types in teleosts are represented. In adult fish, lls are the same structural type in all parts of lateral line in any one specimen, but number of tubules and their orientation may vary. In juvenile fish, except for one species, the structural type of every lls changes with growth, and this process progresses along the lateral line in the direction of development typical for the species. Definitive structural type of the lls is not determined by common scale type and size, presence or absence of nerve foramen on lls, scale overlapping or time of initiation of scales and trunk canal. Development pathways are proposed in which terminal states correspond to the final development of the most complex lls type in Cyprinus carpio, Carassius carassius, Oncorhynchus mykiss, Diplodus annularis and Mullus barbatus. The intermediate states of these pathways correspond to other types of lls as examples of pedomorphosis in Perca fluviatilis, Sander lucioperca, Symphysodon aequifasciatus and Hippoglossoides platessoides.

“…Ganoid and calcidermoid scales are similar in that they are not located in scale pockets, being attached to the dermis, and sometimes to each other by bundles of collagen fibres and do not have a bony‐ridge external layer. The current study extends that of Voronina (, ) by categorising LL scales with ganoid and calcidermoid‐like scale plates as Integrated, and LL scales without a tube as Non‐Tubular.…”

“…Unmodified Tubular‐Scalar I (previously designated as aI (Voronina, )): These LL scales have an unmodified posterior margin, a complete tube with a posterior opening on the inner side of an elasmoid scale plate, distant from the posterior margin (Figures a,b and a–g).…”

“…Cranio‐caudal transition from one type to another takes place in 27 species with Tubular‐Scalar LL scales, for example, from Unmodified I to Unmodified III Tubular‐Scalar (Figure a,b) and from Unmodified II to Modified Tubular‐Scalar (Figure c,d). The tube is more developed, and cteni go from absent to present closer to the tail in Variola louti (Vaillant, ) and Samaris cristatus (Voronina, ), and the scale plate is developed in the anterior part and absent in the posterior part of the LL in Percarina species (Vaillant, ) and in Pleuronectes platessa (Märss, Wilson, Lees, Saat, & Špilev, ). There is little variability in Integrated, Non‐Tubular and Tubular types (except incompleteness of the tube in the latter).…”

The trunk canal of fishes is contained within a series of lateral line (LL) scales. To categorise LL scale structural types, and determine their distribution, an analysis of original data was undertaken using light and scanning electron microscopy in combination with a literature survey from over 1,000 species representative of most orders of bony fishes. Our categorisation of LL scales is based on the relationship between the tube, or ossified trunk canal segment, and associated scale. Tubular‐Scalar LL scales consist of a distinguishable tube and elasmoid scale in scale pockets. Four types occur only in species with elasmoid scales. Integrated LL scales do not develop in scale pockets, and their tube is enclosed or extended by a non‐elasmoid scale or spines. Integrated 1 and 2 LL scales co‐occur with ganoid and calcidermoid scales, and Integrated 3 LL scales occur when common scales are absent or elasmoid. Tubular LL scales are tubes only, occurring mainly in scaleless species or with calcidermoid and elasmoid scales. Non‐Tubular LL scales are composed only of a scale, co‐occurring mainly with cycloid scales. There is consistency of LL scale type in many orders, families and genera and the presence of different types within taxa can be meaningful.

Lateral lines, a major sensory modality in fishes, are diverse among taxa, but their intraspecific variation has received limited attention. We examined numbers of superficial neuromasts on the buttressing lateral plates (LP) of 1910 threespine stickleback (Gasterosteus aculeatus Linnaeus, 1758) from 26 ecologically and morphologically diverse populations on the Haida Gwaii archipelago, western Canada. Extending from previous studies, we predicted that (i) highly stained dystrophic localities would have threespine stickleback with elevated numbers of neuromasts per plate due to a greater reliance on non-visual sensory modalities and (ii) that LP count and neuromast numbers per plate would functionally covary with predatory assemblage. We found that there were no differences in neuromast count across major habitats (marine, lake, stream), but clear-water populations and those with predatory fish had significantly more neuromasts per plate than most populations in highly stained dystrophic lakes, the effects being accentuated on the first buttressing plate (LP4). We also report the first evidence that neuromast counts per plate are sexually dimorphic, with males having a greater density of neuromasts in most populations. Two transplant experiments between ecologically opposite habitats indicate that within 12 generations, neuromast counts per plate can rapidly shift in response to a change in habitat.
