Dazzle to survive
Diversification of the stunningly colourful fairy wrasses was propelled by sea-level changes during the last ice age, according to an Australian study published in the journal Systematic Biology.
The resplendent coral fish, from the species-rich Cirrhilabrus genus of the Labridae family, emerged about 10 million years ago. But the genomic study found they diversified just 3–5 million years ago, during the Pliocene/Pleistocene when sea levels were in constant flux.
