Systematics and evolution
The genus ''Sula'' was introduced by the French zoologist
Mathurin Jacques Brisson
Mathurin Jacques Brisson (; 30 April 1723 – 23 June 1806) was a French zoologist and natural philosopher.
Brisson was born at Fontenay-le-Comte. The earlier part of his life was spent in the pursuit of natural history; his published works ...

term ''bobo'', meaning "stupid", as these tame birds had a habit of landing on board sailing ships, where they were easily captured and eaten. Owing to this, boobies are often mentioned as having been caught and eaten by shipwrecked sailors, notably
William Bligh of the
''Bounty'' and his adherents during their famous voyage after being set adrift by
Fletcher Christian and his followers.
Six of the ten extant Sulidae species called ''boobies'' are in the genus ''Sula'', while the three gannet species are usually placed in the genus ''
Morus''.

Behaviour
Boobies hunt fish by diving from a height into the sea and pursuing their prey underwater. Facial air sacs under their skin cushion the impact with the water. Boobies are colonial breeders on islands and coasts. They normally lay one or more chalky-blue eggs on the ground or sometimes in a tree nest. Selective pressures, likely through competition for resource, have shaped the ecomorphology and foraging behaviours of the six species of boobies in the Pacific.
