    • ‘The parapodia are poorly developed and have long branchiae extending dorso-laterally from most of the segments; some of these branchiae remain exposed on the sediment surface, as do the palps.’

    • ‘Unlike land vertebrates or marine mammals, fish don't have lungs, but they do have paired respiratory structures called gills, or branchia.’
    • ‘Due to the violet edging on the branchia and rhinophores, I suspect that it's a young Chromodoris hintuanensis that's ‘in transition’ from the juvenile to the adult pattern rather than a juvenile C. geometrica.’
