By merging concepts from engineering and nature, the new study presents a novel approach to powering UUVs. The current study ...

The flamboyant fish that is one of the deadliest sea animals is the lionfish ...

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 ...

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 ...

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 ...

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 ...

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

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 ...
