We quantified placoid scale morphology and flexibility in the shortfin mako Isurus oxyrinchus and the blacktip shark Carcharhinus limbatus. The shortfin mako shark has shorter scales than the blacktip shark. The majority of the shortfin mako shark scales have three longitudinal riblets with narrow spacing and shallow grooves. In comparison, the blacktip shark scales have five to seven longitudinal riblets with wider spacing and deeper grooves. Manual manipulation of the scales at 16 regions on… 
Morphological Characterization and Hydrodynamic Behavior of Shortfin Mako Shark (Isurus oxyrinchus) Dorsal Fin Denticles
The shortfin mako shark (Isurus oxyrinchus) is one of the fastest marine fishes, reaching speeds of up to 70 km·h−1. Their speed is related to the skin surface design composed of dermal denticles.
Relationship Between Skin Scales and the Main Flow Field Around the Shortfin Mako Shark Isurus oxyrinchus
The aim of this study was to reveal potential relationship between the main flow field around a shortfin mako shark and the surface morphology of shark skin. Firstly, a numerical simulation using the
Comparative squamation of the lateral line canal pores in sharks.
The first quantitative data on lateral line pore squamation patterns in sharks suggests that this pattern may reduce boundary layer turbulence and affect lateral line sensitivity, and the hypothesis that divergent orientation angles are exclusively found in fast-swimming shark species was tested.
Morphological characterization of dermal denticles of the Broadnose Sevengill Shark Notorynchus cepedianus (Elasmobranchii: Hexanchidae)
Dermal denticles measures showed significant morphological differences between body regions as well as stages of development, but not between sexes, which could be useful as diagnostic characters to identify the stage of development at which the landed and marketed specimens are found.
The denticle surface of thresher shark tails: Three‐dimensional structure and comparison to other pelagic species
It is reported that tails of thresher embryos have a membrane that covers the denticles and reduces surface roughness, and evidence that these denticles are being replaced by new denticles that emerge from the skin below.
Microscopic aspects of the nictitating membrane in Carcharhinidae and Sphyrnidae sharks: a preliminary study
It is hypothesized that the morphological simplification observed in the membrane when compared to the dermal denticles from the skin, is an evolutionary trait that evolved to improve the dynamic and biomechanics of this highly mobile structure allowing this way, a rapid and efficient protection against abrasion, mainly during predation events.
Comparison of the Morphology, Structures and Mechanical Properties of Teleost Fish Scales Collected from New Zealand
The mechanical properties and structures of fish scales have generated considerable research interest, however, comparative studies for different fish scales from different water regions have not
Bioluminescent-like squamation in the galeomorph shark Apristurus ampliceps (Chondrichthyes: Elasmobranchii)
Galeomorph sharks constitute the most taxonomically and ecologically diverse superorder of living selachians. Despite comprising several typically deep-water taxa, no bioluminescent species have been
Sexual Dimorphisms in the Dermal Denticles of the Lesser-Spotted Catshark, Scyliorhinus canicula (Linnaeus, 1758)
The length, width and density of the dermal denticles of mature male and female S. canicula are sexually dimorphic across the integument in areas where males have been observed to bite and wrap themselves around females.
Mucus Matters: The Slippery and Complex Surfaces of Fish
Topographic, three-dimensional, analyses of fish skin surfaces from seven species with the mucus, epidermis, and relative positions of scales intact are presented to show a previously unexplored axis of diversity in fish: how mucus and epidersmis interact with scale morphology to create surface texture.


Dorsal fin in the white shark, Carcharodon carcharias: A dynamic stabilizer for fast swimming
The overall results indicate that the dorsal fin of C. carcharias functions as a dynamic stabilizer and that the dermal fibers are crucial to this role.
Caudal fin in the white shark, Carcharodon carcharias (Lamnidae): A dynamic propeller for fast, efficient swimming
Overall, the anatomy and mechanics of the dorsal lobe of C. carcharias facilitate greater control of movement compared to the ventral lobe, and provides considerable potential for an elastic mechanism in the animal's swimming motions and consequently for energy conservation.
Functional morphology of the radialis muscle in shark tails
Electromyography of the caudal muscles of dogfish swimming steadily and a nonconformity to the typical anterior to posterior wave of muscle activation in fish swimming, in combination with anatomical positioning of the radialis muscles and stratum compactum, suggests that radialis activity may have a postural function to stiffen the fin, and does not function as a typical myotomal muscle.
Hydrodynamic Aspects of Shark Scales
Ridge morphometrices on placoid scales from 12 galeoid shark species were examined in order to evaluate their potential value for frictional drag reduction. The geometry of the shark scales is
Convergent evolution in mechanical design of lamnid sharks and tunas
It is demonstrated that not only have lamnids and tunas converged to a much greater extent than previously known, but they have also developed morphological and functional adaptations in their locomotor systems that are unlike virtually all other fishes.
Food habits of the shortfin mako, Isurus oxyrinchus, off the southwest coast of Portugal
The shortfin mako, Isurus oxyrinchus, is caught in the eastern North Atlantic as a regular bycatch of the surface-drift longline fishery, mainly directed towards swordfish, Xiphias gladius, and stomachs showed teleosts to be the principal component of the diet, occurring in 87% of the stomachs and accounting for over 90% ofThe contents by weight.
Predation by White Sharks Carcharodon carcharias (Chondrichthyes: Lamnidae) Upon Chelonians, with New Records from the Mediterranean Sea and a First Record of the Ocean Sunfish Mola mola (Osteichthyes: Molidae) as Stomach Contents
The white shark may be the chief marine predator of adult chelonians in the Mediterranean Sea, albeit the impact of this predation upon turtle populations is nominal compared to other sources of mortality.

Characteristics of the dermal covering in Platyrhinidae (Chondrichthyes, Rhinobatiformes)
The characteristics of the dermal covering of Platyrhinidae indicate that they can be discriminated from the other Rhinobatiformes by the absence of corono-peduncular relief of the tubercles.
Movement patterns, depth preferences, and stomach temperatures of free-swimming juvenile mako sharks, Isurus oxyrinchus, in the Southern California Bight
Stomach content analyses of four makos captured at the end of tracking verified the occurrence of feeding events as indicated by changes in stomach temperature, and body size was positively correlated with both maximum and average stomach temperature.
