Once they have laid their eggs, fish become "young" again: Study
The physical relief—in body weight—that temperate fish like cod and Atlantic herring experience after they spawn for the first time allows them to breathe in more oxygen and develop a voracious appetite, all of which leads to a rapid increase in.....»»
Model shows how fish synchronize tail fins to save energy
Researchers from Tohoku University have developed a model that simulates the motion of fish tail fins. The model uncovers the underlying mechanisms behind a commonly observed phenomenon in fish: how they synchronize the movement of their tail fins, r.....»»
