Fish evolution after the Devonian followed two main paths. The Chondrichthyes (sharks and rays) radiated several times, and achieved high diversity at times. The Osteichthyes (bony fishes) also radiated several times, and they have become a major element of marine and freshwater life today. Most...
*alternative titles include “Looking a gift seahorse (genome) in the mouth”, “My kingdom for a seahorse genome”, “Hold your seahorses“, and “The galloping evolution of seahorses“. Let’s face it, seahorses, pipefishes, and seadragons are messed up. That’s not a subjective opinion...

Causes and Course of Qrganic Evolution," he propounded the thesis that "organisms evolved first in fresh-water areas, and only by degrees spread into marine surroundings," and the first and larger of the two volumes now under review deals with the application of this view to the fishes. T...
Unprecedented global bleaching events have led to extensive loss of corals. This is expected to lead to extensive losses of obligate coral-dependent fishes. Here, we use a novel, spatially-matched census approach to examine the nature of fish-coral dependency across two mass coral bleaching events...
the dermal skeletons of living fish like sturgeon and lungfish to understand the patterns they were seeing in the fossils. They saw some of the same asymmetrical differences between the top and bottom of the fins, suggesting that those changes played a larger role in the evolution of fishes. ...

The habit of switching sex appears to have developed during fish evolution multiple times in separate families, and though in all of them a suite of genetic and hormonal triggers come into play, the enzyme aromatase appears to be the key. ...
A unique presentation of a modern, cladistically based classification of all the major living and fossil fish groups, this indispensable reference helps scientists and others identify and classify specimens, make familial connections, understand the evolution of fishes, and springboard in... (展开...
