The Evolutionary Constraints Of Fish Skulls

Most people think that biting is the way that aquatic creatures capture prey. Not so, instead suction is far more common. That is why the diversity of skull shapes in biters is so much greater, according to a new study. Suction feeding limits skulls shapes because of the structural requirements for suction feeding.  "When you look at the skulls of biters, the diversity is astounding compared to suction feeders," said Rita Mehta, assistant professor of ecology and evolutionary biology at U.C. Santa Cruz.  read more
