The cartilaginous elephant shark has a basal phylogenetic position useful for understanding jawed vertebrate evolution. Survey sequencing of its genome identified four Hox clusters, suggesting that, ...

The digestive tract of teleost fish exhibits an impressive degree of histological diversity that reflects the range of feeding strategies found in this group. Detailed microscopic studies have ...

in New York have discovered a remarkable effect in a cold polar fish which lives in the Antarctic and Arctic. Q: What is it called? A: Right away, we have a problem. They call it the teleost fish, but ...

What is the origin of the ancestors of present-day fish? What species evolved from them? A 50-year-old scientific controversy revolved around the question of which group, the 'bony-tongues' or the ...

The most common lineages of fish found today in oceans, lakes, and rivers evolved about the same time as mammals and birds, a new Yale University-led study shows. A genetic analysis by Yale ...

Despite their obvious physical differences, elephants, lizards and trout all have something in common. They possess elongated, flexible structures at the rear of their bodies that we call tails. But a ...
