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

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 ...

Underwater drones usually use electric motor propeller drives. Researchers now want to eliminate their disadvantages with an artificial fish fin.

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 ...

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 ...

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 ...

Owners should also watch out for infection and diseases such as fin rot, dropsy, and swim bladder disease. While Betta fish can tolerate dirty water for a short period, long exposure can cause ...

With a face only a mother could love, the southern stargazer fish burrows beneath the sand with only their mouth, nostrils and eyes visible.

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 ...
