Relative to stream conspecifics, lake fish had more posteriorly positioned first dorsal and pelvic fins, and shorter ...
This is where one of the bestnatural selection examplescame into play. Some species of fish that lived near the coast developed a strange mutation: the ability to push themselves along in the mud and sand on the shore with their fins. ...
Fish - Migration, Communication, Adaptation: Fish behavior is a complicated and varied subject. They perceive the world around them by the usual senses of sight, smell, hearing, touch, taste, and by special lateral line water-current detectors. Specializ
Faced with the rapidly flowing water in the Tibetan Plateau, a group of catfish has evolved greatly enlarged pectoral fins with more numbers of fin-rays to form an adhesive apparatus. However, the genetic basis of these adaptations in Tibetan catfishes remains elusive. In this study, we ...
