A team of U.S. National Science Foundation-funded scientists has identified at least 11 species of fish suspected to have land-walking abilities.The findings are based on CT scans and a new evolu...
In Sex-Changing Fish,Male-Typical Sexual Behavior Associated With Elevated Expression Of Male Sex Hormone Receptors In Muscles
Sex-Changing Fish Male-Typical Sexual Behavior Male Sex Hormone Receptors Muscles
2017/7/21
Sex-changing fish exhibit differences in androgen receptor (AR) expression in muscles that are highly sensitive to androgens (male sex hormones) and essential for male courtship behavior, according to...
As fins evolve to help fish swim,so does the nervous system
fins evolve fish swim nervous system
2017/4/27
The sensory system in fish fins evolves in parallel to fin shape and mechanics, and is specifically tuned to work with the fish’s swimming behavior, according to new research from the University of Ch...

While a dominant male fish from northern Mexico mates with a female, a small fella bides his time in the offing. Suddenly, the little guy darts in ahead of Mr. Big and plants his seeds on freshly laid...
Personality Changes Can Affect Fish Body Shape,Locomotion
Personality Changes Fish Body Shape Locomotion
2016/6/12
Evolutionary change in one trait can elicit evolutionary changes in other traits due to genetic correlations. This constrains the independent evolution of traits and can lead to unpredicted ecological...
A recent study provides new evidence that larvae swim faster, straighter and more consistently in a common direction when together in a group. The research led by scientists at the University of Miami...
Lightly brush your fingertips across your keyboard. What do you feel? The smoothness of plastic? Ridges, gaps, maybe a sticky key? Bumps on the F and J keys? The human fingertip is a finely tuned sens...
Genetic mechanism found for fish adaptations to pollution
Genetic mechanism fish pollution
2016/2/23
A Washington State University biologist has found the genetic mechanism that lets a fish live in toxic, acidic water. The discovery opens new insights into the functioning of other “extremophiles” and...

Female fish that avoid mating related species shun some of their own
2015/3/18
A new study offers insight into a process that could lead one species to diverge into two, researchers report in The American Naturalist.Avoidance of another species can lead female fish to avoid mati...
On June 22-24, 2015, the 5th Fish Passage Conference will be held for the first time in Europe, in the city of Groningen, The Netherlands. Hundreds of researchers, educators, practitioners, funders an...
