“…Here, we selected other four fishes (Grass carp, Striped bass, Carassius auratus and Parabramis pekinensis) as references [10, 15, 31] and tested the penetration force of their skins. The average penetration force was shown in Table 3.…”

“…As the stratum compactum is composed of the cross‐helical arrangement of fibrous layers, it also displays a remarkable mechanical response in the tension, puncture and laceration tests, and therefore supplies appreciable mechanical protection to the fish body [17]. The grass carp (Ctenopharyngodon idellus) skin, as a high‐grade biological leather, shows different tensile responses in the head, body and tail regions, where the skin of the tail exhibits the maximum tensile strength, and the skin of the head exhibits the minimum tension strength [15]. Although the mechanical properties of the fish skin in different regions show some differences, this study still reveals that the grass fish skin is a high strength natural material.…”

“…The scales of the Paramisgurnus dabryanus reach a good tradeoff between flexibility and defense through a discrete bony layer structure embedded into its internal fibrous layers [13]. However, researchers have recently discovered that fish skin probably also plays a very important role in structural support and protective functions for the fish body [14, 15].…”

Chinese sturgeon (Acipenser sinensis) fish skin is an excellent natural material with remarkable mechanical properties owing to the unique structures of the helical stacking fibres. In this work, the authors studied the potential role of the sturgeon fish skin in the protective function through testing and analysed the structural features and mechanical properties of the stratum compactum in the fish skin. Scanning electron microscopy images of the sturgeon fish skin revealed that the skin was primarily composed of the stratum compactum. The stratum compactum was characterised by the helically arranged fibre structures and the helical-ply angle decreased from the anterior region of the fish body to the posterior region. Mechanical tests containing tension and penetration experiments demonstrated that the stratum compactum provided the sturgeon fish skin the capability to effectively resist bite and laceration by predators. Furthermore, the experimental results also confirmed that the sturgeon fish skin showed two distinct mechanisms against tension and penetration. These findings may provide a novel biomimetic design template for both flexible and tough body armour.

“…As a high-grade leather material, the mechanical properties of fish skin-such as its tensile strength-are important indicators for measuring the intrinsic quality of leather. Ye et al carried out tension tests on the skin of grass carp, and the results showed that although its mechanical properties differ in different areas, it has good tensile strength and is an ideal leather material (Ye et al, 2018). However, although previous studies have subjected fish skin to mechanical tests, the aim in most cases was to show that fish skin has a functional role similar to that of an external tendon, which helps to improve a fish's swimming efficiency.…”

“…It is found that the fibrous layers play an important role in the protective function of scales, not only increasing significantly their tensile strength and fracture toughness but also delaying the catastrophic fracture failure of the bony layers (Sherman et al, 2017; Yang et al, 2014). These fibrous layers are also present in fish skin tissue and probably provide the skin with good mechanical properties (Ye et al, 2018).…”

Benefitting from its unique helically arranged fiber structures, fish skin is a superior biological protective tissue. Reported here is a study of the microscopic morphological characteristics and mechanical properties of the skin of three species of fish, that is, Taihu white fish (Erythroculter ilishaeformis), grouper (Cichlasoma managuense), and yellowfin seabream (Ditrema temminckii Bleeker), revealing the special protective mechanisms of fish skin. Experiments involving scanning electron microscopy show that the stratum compactum is the main part of fish skin and comprises helically stacked fibers, with the helical ply angles of the fibrous layers differing significantly for the different fish species and in different regions of their bodies. Tension and penetration experiments show that fish skin provides a fish's body with considerable mechanical protection from lacerations and bites inflicted by its natural enemies. Moreover, the mechanical tests show that fish skin has two different defensive mechanisms against tension and penetration loads, thereby offering a novel idea for designing body armor that is both flexible and tough.

Fish skin is a biological material with high flexibility and compliance and can provide good mechanical protection against sharp punctures. This unusual structural function makes fish skin a potential biomimetic design model for flexible, protective, and locomotory systems. In this work, tensile fracture tests, bending tests, and calculation analyses were conducted to study the toughening mechanism of sturgeon fish skin, the bending response of the whole Chinese sturgeon, and the effect of bony plates on the flexural stiffness of the fish body. Morphological observations showed some placoid scales with drag-reduction functions on the skin surface of the Chinese sturgeon. The mechanical tests revealed that the sturgeon fish skin displayed good fracture toughness. Moreover, flexural stiffness decreased gradually from the anterior region to the posterior region of the fish body, which means that the posterior region (near the tail) had higher flexibility. Under large bending deformation, the bony plates had a specific inhibition effect on the bending deformation of the fish body, especially in the posterior region of the fish body. Furthermore, the test results of the dermis-cut samples showed that the sturgeon fish skin had a significant impact on flexural stiffness, and the fish skin could act as an external tendon to promote effective swimming motion.
