SULIDAE
Sulidae
The bird family Sulidae comprises the gannets and boobies. Collectively called sulids, they are medium-large coastal seabirds that plunge-dive for fish and similar prey. The ten species in this family are often considered congeneric in older sources, placing all in the genus Sula. However, Sula and Morus can be readily distinguished by morphological and behavioral and DNA sequence characters. Abbott's Booby is given its own genus as it stands apart from both in these respects. It appears to be a distinct and ancient lineage, maybe closer to the gannets than to the true boobies.The above text is a snippet from Wikipedia: Sulidae
