A new iguana has been discovered in the central regions of Fiji. The colorful new species, named Brachylophus bulabula, joins only two other living Pacific iguana species, one of which is critically endangered. The scientific name bulabula is a doubling of bula, the Fijian word for ‘hello,’ offering an even more enthusiastic greeting.

Picking a mate isn’t easy—if you are a female iguana. In a study published in the June 27th issue of the online, open-access journal PLoS ONE, Maren Vitousek of Princeton University and colleagues found that female Galбpagos marine iguanas spend a lot of energy picking a mate from a wide range of suitors – energy they could otherwise spend foraging, producing eggs, or avoiding predators.
