fish

Once thought to be silent, fish turn out to produce a range of vocalizations—so polluting the oceans with noise could pose a danger to them.

These tiny reef fish harbor luminous bacteria, and the chromosome-level assembly of the species’ genome may facilitate the duo’s use as a vertebrate model for symbiosis.

Scientists find that two species can be trained to distinguish quantities that vary by one.

Researchers determined the season during which the meteor struck by studying the bones of fish excavated from a contentious field site.

The Scientist spoke with cognitive neuroscientist Ronen Segev about how he taught goldfish to maneuver a moveable tank over land toward a visual target.

Moving collectively on the water surface could help protect schools of fish from being eaten by predatory birds.

Shared features, such as thick, slimy skin and a throat filled with teeth, suggest that medusafishes are all related.

The high-quality genome sequence sheds light on the colorful nature of these popular aquarium fish.

An analysis suggests that a commercially important mass migration of fish may have no real adaptive value.

A modeling study estimates that by drastically reducing fish biomass over the past century, industrial fishing may be affecting ocean chemistry, nutrient fluxes, and carbon cycling as much as climate change.

A study of feeding behavior suggests the fish feed differently in front of their partners—a behavioral feature also found in primates.

Research in recent decades has explored how animals other than humans perceive different numbers of objects

Researchers discover surprisingly high levels of genetic diversity among the colorful male morphs of a freshwater fish.

Bettas were likely the first fish welcomed into human homes. Now, scientists are welcoming them into the lab to learn how genes dictate their appearance and behavior.

After eight weeks of exposure to ecologically plausible levels of methamphetamines, the fish tended to prefer meth-laced water over water without the drug.

A New York Times investigation’s failure to amplify tuna DNA from Subway’s tuna salad sandwiches likely says more about the complexities of identifying processed fish than about the ingredients.

This evolutionarily ancient fish species has a lifespan that’s around five times longer than previously thought, and a gestation time of more than five years.

The use of pesticides has decreased in the US by more than 40 percent since 1992, but the emergence of more-potent chemicals means that they are far more damaging to many species.

The Scientist Social Club talked to the author and her dad, Chris Miller.
