MIF examined specimens of hatchlings and juveniles of Octopus vulgaris, or common octopus, as part of a project led by Roger Villanueva from the Institut de Ciències del Mar at CSIC in Spain. These structures are present in embryos but disappear before the adult stage, and their function is unknown. The Mesoscopic Imaging Facility (MIF) at EMBL Barcelona was recently involved in studying one unique feature of the octopus: the ephemeral structures on the surface of their skin called Kölliker’s organs.

These soft-bodied cephalopods have a strikingly sophisticated nervous system, camera-like eyes, three hearts, and an extraordinary ability to switch the colour and texture of their skin to mimic their background in the blink of an eye. Cuttlefish, squids and octopuses, for example. Some of the most amazing creatures live in the deep blue sea.
