title: Evolution: how a barnacle came to parasitise a shark.
abstract: A new study on a parasitic barnacle that lives on a deep sea shark found that its closest living relatives are rocky shore barnacles. The findings provide insight into barnacle phylogeny and raise new questions about the evolution of parasitism.
