Like people, blue crabs aren't all the same sizes and shapes. Now Rutgers scientists have discovered substantial differences in the body structures of larval crab siblings and among larvae from different mothers. And that can mean the difference between an early death and survival into adulthood for this important commercial and recreational species.
Unlike other crab species, these larval differences aren't related to the size of their mothers, according to a study in Biological Bulletin. The differences can mean that babies from certain mothers may swim or feed more efficiently than others, giving them an advantage.
