The functional capacities of animals are a primary factor determining survival in nature. In
this context, understanding the biomechanical performance of animals can provide insight …

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 …

The northern clingfish (Gobiesox maeandricus) has a suction-based adhesive disc that can
stick to incredibly rough surfaces, a challenge for stiff commercial suction cups. Both …

Waterfall-climbing gobiids from oceanic islands use a suction-based adhesive mechanism
formed by fused pelvic fins (pelvic sucker) and exhibit rock-climbing behavior during …

Dams and other man‐made barriers impair upstream fish migration and thus threaten fish
populations that need access to upper river reaches to complete their life cycle. For many …

The morphology of an individual can improve its ability to escape predators and ultimately its
chances of survival. Sicydiine fishes reproduce in rivers, and their larvae develop in the sea …

Suckermouth armoured catfish (Loricariidae) are a highly speciose and diverse freshwater
fish family, which bear upper and lower lips forming an oral disc. Its hierarchical organisation …

In riverine ecosystems, downstream drag caused by fast‐flowing water poses a significant
challenge to rheophilic organisms. In neotropical rivers, many members of a diverse …

Relationships between body shape and escape performance are well established for many
species. However, organisms can face multiple selection pressures that might impose …

Many animals frequently transition between different media while navigating their
heterogeneous environments. These media vary in compliance, moisture content, and other …
