If you have the ability to change sex up to 20 times, would you stay faithful to your mate, like the chalk bass? Apparently, this bass is not all about that bass.
Scientists are wary that the "Finding Dory" film might translate a wrong message to its audience, as people might scramble to have their own Dory--a wild, tropical marine fish--in their aquariums.
A photo captured by Tim Samuel literally gives us a picture of what it's like to be trapped inside a jellyfish's body.
Scientists captured a video of a deep-sea fish with 'feet.'
Humans may be speeding up the otherwise slow process of evolution by introducing new species to unfamiliar areas. Consequently, heightened competition leads to a loss of diversity.
In a recent study from Nagoya University in Japan, researchers found scale-eating cichlid fish from Africa’s Lake Tanganyika become either right-handed or left-handed as the mature. It is believed that such specialization gives the fish an evolutionary advantage.
A bighead carp weighing about 25 pounds was recently captured in the Minnesota River. This raises concern about potential effects invasive fish can have on the state's waterways.
Called "extremophiles," certain small fish are predisposed to remain lively and (well) alive in toxic waters when other fish cannot do so.
Researchers have for the first time found that at least one species of fish can sense touch using their pectoral fins, much like humans use their fingertips to get a feel for their surroundings.
We've all heard about how noise pollution negatively impacts marine environments. But a recent study suggests that motor boats, rather than large cargo ships, easily stresses young damselfish which ultimately gives their predators the upper hand.
Although the invasive species called Regal Damselfish may not make its way too far into the Gulf of Mexico, researchers say the Gulf's southern reefs can expect to see a lot more of these invasive fish relatively soon.
"Twilight zone" reef fish face numerous threats when diving deep underwater, but those with forked tails may have an advantage: they can swim quietly past predators and evade natural disasters such as cyclones and coral bleaching.
Fish chatter with each other in order to stay close to one another and better their chances of safety. While contact calls are generally used for mating purposes or to defend one's territory, this is the first time researchers have observed fish communicating to maintain group cohesion.
Hydroelectric dams planned for the tropical rivers of Mekong, Amazon and Congo could destroy local fish habitats and cause human populations to relocate, too. A team of researchers suggest new ways to evaluate the cost and benefits of these massive structures.
