The current study presents a novel underwater propulsion system that is modeled after the caudal fin of fish, particularly ...

Adipose fins are small, fleshy and usually not as elaborately structured as other fins. Although some 6,000 species of fish—including trout, catfish, and salmon—have them, relatively few researchers ...

It has many of the rods that are very characteristic of lobe-finned fish fins. The fin is rather large, about the size of a tennis racket head. We can see the internal bony structure that showed ...

Modeled after the rear fin of a tuna fish, the replica will propel the drone into deep waters with more quickness and maneuverability than present-day versions. "I'm taking inspiration from biological ...

Researchers at the University of Maryland are developing a new unmanned underwater vehicle (UUV) that mimics the movement of ...

Tiktaalik roseae had fish-like fins, a flattened skull (similar to a crocodile), and is thought to have lived in shallow water, using its fins to prop itself up ...

The coelacanth has gills similar to those of fish living at the depths in which ... these fishes' paired lobe fins are supported by the same basic bones as your arms and legs.

Robots could benefit from research into fish fins at the University of Colorado Boulder. Engineer Professor Francois Barthelat has been examining the mechanics that allow fins to be flexible and stiff ...

Huertas-Cerdeira analyzed what makes fish such good swimmers. Fish change the stiffness of their fins depending on the situation as they swim through the water, thus reacting to the forces of the ...

Their streamlined torpedo shape helps them gather enough underwater speed to break the surface, and their large, wing-like pectoral fins get them airborne. Flying fish are thought to have evolved ...
