“…is suggests that strong adhesion is an important component of powerburst climbing, as larger pelvic disks generate a stronger adhesive force (Blob et al 2008). In a study by Maie and Blob (2021), powerburst climbers were found to engage their pelvic disk signi cantly longer than inching gobiids due to long rest periods during waterfall ascent. e same movement pattern was consistently observed in this study, with most successful S. elegans stopping at least once before reaching the top of the ramp.…”

Amphidromy is a life history strategy that confers an adaptive edge to the extreme hydrological variability in tropical island streams, where organisms migrate between fresh and salt water. is allows for recolonization of stream habitats following large disturbances that carry juveniles to sea. Many members of the sh family Gobiidae are amphidromous and have evolved the ability to climb waterfalls in order to access upstream breeding habitats and evade low elevation predators. Two distinct climbing strategies have been observed across gobiids: powerburst climbers ascend barriers in a series of bursts and stops, while inching climbers move steadily with alternating head and body movements. Morphology has been shown to in uence inching gobiid climbing ability but has yet to be investigated in powerburst climbers. is study examines the relationship between morphology and climbing ability in the adult powerburst climber Stiphodon elegans on Moorea, French Polynesia, using an arti cial waterfall and morphological analysis. Climbing success was found to be signi cantly and positively associated with pelvic disk diameter, but not variation in head or body morphology. Reaching a better understanding of gobiid functional morphology is necessary for interpreting and predicting elevational distributions, which can inform tropical island stream management and gobiid conservation.

“…It was thought that this might represent a new movement mode: aquatic propulsion supplements the mechanisms for the generation of terrestrial thrust [76]. In contrast, inching climbers, represented by Sicyopterus stimpsoni (Figure 11d), relied on the alternate attachment of mouthparts and pelvic fin suckers (Figure 11e) to achieve inch-by-inch climbing on vertical substrates [21,[83][84][85]. Their juveniles develop in the ocean for up to six months and undergo a rapid metamorphosis (48 h) before climbing, including an enlargement of the upper lip, a shift in mouth position from terminal to ventral, and a sudden loss of weight [18,84].…”

“…This allows them to climb inch-by-inch for several seconds at a rate of 0.21 ± 0.01 BL s −1 : the mouthpart first attaches to the substrate, the posterior body is pulled up, and with the attachment of the pelvic sucker, the mouthpart releases and the anterior body continues to advance [18]. It was found that the suction force of the mouthpart was much lower than that of the pelvic sucker [20,85,86]. This also confirmed that the pectoral fins spread maximally over the climbing surface during mouthpart attachment, aiding crawling by imparting maximum contact and friction [20].…”

In nature, some fish can adhere tightly to the surface of stones, aquatic plants, and even other fish bodies. This adhesion behavior allows these fish to fix, eat, hide, and migrate in complex and variable aquatic environments. The adhesion function is realized by the special mouth and sucker tissue of fish. Inspired by adhesion fish, extensive research has recently been carried out. Therefore, this paper presents a brief overview to better explore underwater adhesion mechanisms and provide bionic applications. Firstly, the adhesion organs and structures of biological prototypes (e.g., clingfish, remora, Garra, suckermouth catfish, hill stream loach, and goby) are presented separately, and the underwater adhesion mechanisms are analyzed. Then, based on bionics, it is explained that the adhesion structures and components are designed and created for applications (e.g., flexible gripping adhesive discs and adhesive motion devices). Furthermore, we offer our perspectives on the limitations and future directions.

“…Over a long period of evolution, organisms have developed unique and exceptional adaptations to thrive in their natural environments. For example, many animals in nature possess adhesive capabilities [1][2][3]. Animals are able to firmly adhere to different surfaces in their environment using their adhesive abilities, helping such organisms with fundamental survival tasks like crawling, hunting, grabbing, and fleeing [4][5][6][7][8].…”

To date, research on abalone adhesion has primarily analyzed the organism’s adhesion to smooth surfaces, with few studies on adhesion to non-smooth surfaces. The present study examined the surface morphology of the abalone’s abdominal foot, followed by measuring the adhesive force of the abalone on a smooth force measuring plate and five force measuring plates with different surface morphologies. Next, the adhesion mechanism of the abdominal foot was analyzed. The findings indicated that the abdominal foot of the abalone features numerous stripe-shaped folds on its surface. The adhesion of the abalone to a fine frosted glass plate, a coarse frosted glass plate, and a quadrangular conical glass plate was not significantly different from that on a smooth glass plate. However, the organism’s adhesion to a small lattice pit glass plate and block pattern glass plate was significantly different. The abalone could effectively adhere to the surface of the block pattern glass plate using the elasticity of its abdominal foot during adhesion but experienced difficulty in completely adhering to the surface of the quadrangular conical glass plate. The abdominal foot used its elasticity to form an independent sucker system with each small lattice pit, significantly improving adhesion to the small lattice pit glass plate. The elasticity of the abalone’s abdominal foot created difficulty in handling slight morphological size changes in roughness, resulting in no significant differences in its adhesion to the smooth glass plate.
