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.

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 ...

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.

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 ...

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 ...
