To swim like a tuna, robotic fish need to change how stiff their tails are in real time
Underwater vehicles haven't changed much since the submarines of World War II. They're rigid, fairly boxy and use propellers to move. And whether they are large manned vessels or small robots, most underwater vehicles have ...

Engineers uncover the secrets of fish fins
Peer into any fishbowl, and you'll see that pet goldfish and guppies have nimble fins. With a few flicks of these appendages, aquarium swimmers can turn in circles, dive deep down or even bob to the surface.

A robotic fish tail and an elegant math ratio could inform the design of next- generation underwater drones
Underwater vehicles are typically designed for one cruise speed, and they're often inefficient at other speeds. The technology is rudimentary compared to the way fish swim well, fast or slow.

New, tiny battery powers big insight into fish passage for hydropower
With the worldwide decline of lamprey and eel populations, tracking their movement and survival is a first step toward conservation. However, some tracking sensors—or tags—are too large for smaller fish.

Discovery of ray sperms' unique swimming motion demonstrated with bio-inspired robot
It is generally agreed that sperm "swim" by beating or rotating their soft tails. However, a research team led by scientists from City University of Hong Kong (CityU) has discovered that ray sperms move by rotating both the ...

New algorithm mimics electrosensing in fish
While humans may struggle to navigate a murky, turbid underwater environment, weakly electric fish can do so with ease. These aquatic animals are specially adapted to traverse obscured waters without relying on vision; instead, ...

Fish-inspired robots coordinate movements without any outside control
Schools of fish exhibit complex, synchronized behaviors that help them find food, migrate and evade predators. No one fish or team of fish coordinates these movements nor do fish communicate with each other about what to ...

Tetrapods
A fish is any aquatic vertebrate animal that is typically ectothermic (or cold-blooded), covered with scales, and equipped with two sets of paired fins and several unpaired fins. Fish are abundant in the sea and in fresh water, with species being known from mountain streams (e.g., char and gudgeon) as well as in the deepest depths of the ocean (e.g., gulpers and anglerfish).
Food prepared from fish is also called fish, and it is an important food source for humans. They are harvested either from wild fisheries (see fishing) or farmed in much the same way as cattle or chickens (see aquaculture). They are also exploited by recreational fishers and fishkeepers, and are exhibited in public aquaria. Fish have had a role in many cultures through the ages, ranging from deities and religious symbols to the subjects of books and popular movies.
