Coral reefs are home to a spectacular variety of fish. A new study shows that much of this diversity is driven by a relatively recent innovation among bony fish -- feeding by biting prey from surfaces ...

The mighty tuna is more closely related to the delicate seahorse than to a marlin or sailfish. That is one of the surprises from the first comprehensive family tree, or phylogeny, of the "spiny-rayed ...
