“…Bone formation along the tube walls and roof, and bone resorption along the surface of the scale part inside the tube, is observed in zebrafish LL scales in which the bony-ridge layer under the tube gradually disappears during canal morphogenesis (Wada et al, 2014). Decalcified areas around the tube, possibly indicating osteoclast activity, are noticeable in the LL scales of adults of some species (DeLamater & Courtenay, 1973;Jawad, 2005;Voronina & Hughes, 2013).…”

“…Cteni are present in the Unmodified Tubular-Scalar III LL scales in some Cynoglossus species, but are absent (i.e., Modified Tubular-Scalar) in others. The position of the posterior opening is distant from the posterior margin of the scale plate (i.e., Unmodified Tubular-Scalar I LL scales) in Lates calcarifer (Figure 5a) and close to it and joined with the opening for the canaliculus in L. niloticus (i.e., Unmodified Tubular-Scalar II LL scales) (Jawad, 2005). There are Modified Tubular-Scalar or Tubular LL scales in Scophthalmus species with cycloid common scales or scutes, respectively (Figure 11).…”

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.

“…The sculpture characteristics of scales have occasionally been used as taxonomic criteria for cypriniform (Cyprinidae and Cobitidae) fish species (e.g. Kaur & Dua 2004;Jawad 2005;Johal et al 2006;Jawad & Al-Jufaili 2007), but the fine details of the external surface of scales and tubercles have more often been illustrated in publications on histology (e.g. Sire et al 1997;Meunier & Brito 2004).…”

Small to very small ossified structures (ossicles) such as cephalic horns, dermal tubercles, fin-ray rods, lateral-line canal segments, branchial tooth plates and gill-raker tubercles of three species of the teleostean fish family Cottidae inhabiting the Baltic Sea are described and for the first time illustrated with SEM images, with emphasis on their microscopic external features. The morphology and sculpture of these small ossicles notably differ in the three genera, but differences can also occur between males and females, as documented here in Myoxocephalus scorpius (Linnaeus). The detailed features of such ossicles are potentially useful for taxonomic identification in sea-floor sediments or gut contents, in a manner similar to their use in many modern and fossil fishes, and may also prove useful as phylogenetically important characters at generic and familial levels

“…Most descriptions of lls are for those classified here as type aI, which are found for species in the Osteoglossiformes (Taverne 1977), Salmoniformes, in particular Salmonidae (Cavender 1980; Holčik 1982), Aulopiformes (Spix and Agassiz 1829; DeLamater and Courtenay 1973; Jawad and Al‐Jufaili 2007), Cypriniformes, in particular Cyprinidae (Cockerell and Allison 1909; Chu 1935; Tandon and Chaudhary 1983–1984; Jawad 2005a), Characiformes (Spix and Agassiz 1829), Scorpaeniformes (Imamura 1996) and Perciformes, in particular the Sparidae and Mullidae (Popovici 1931; Munro 1949; Masuda and Tanaka 1962; Morales‐Nin and Fauquet 1984; Webb 1990a,b; Jawad 2005b). Lls described for some perciforms, in particular species in the Percidae, are classified here as type aII (Mohr 1916; Jawad 2005a) and for others, in particular Cichlidae, as type aIII (Peters 1973; DeLamater and Courtenay 1973; Webb 1989). Type bII classified lls are found in hexagrammid species (Scorpaeniformes) (Wonsettler and Webb 1997), with type bII and bIII lls being common in the families of Pleuronectiformes, in particular Pleuronectidae (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.
