Energy reserves in the Arctic

'Invertebrate larvae face many challenges before settling on hard ground. They must rely on their energy reserves to sustain the dramatic process of metamorphosis. This photograph shows conspicuous lipid droplets (energy storage) within a late larval stage of an Arctic balanid barnacle. Although barnacles are foundation species worldwide, their tiny size means that they are often overlooked. Here, we highlight the fascinating larval ecology of these invertebrates, that still have secrets to yield.'
