In 1917 Iredale described Sherbornia mirabilis as a peculiar gastropod from Christmas Island in the Indian Ocean. Its remarkable shell morphology leads to questions on functions and adaptations. The greatly expanded apertural shield, three canals and protoconch morphology suggest relationships to different genera and families, which prompts the que...

There is a lack of standardised imaging methods for marine zooplankton due to the difficulty of manipulating small and often fragile specimens. Yet, standardised 2D photographs and 3D scans provide important morphological information to accompany DNA-barcoded specimens for reference databases such as the Barcode of Life Data System (BOLD). Shelled...

Little is known about when and how planktonic species arise and persist in the open ocean without apparent dispersal barriers. Pteropods are planktonic snails with thin shells susceptible to dissolution that are used as bio‐indicators of ocean acidification. However, distinct evolutionary units respond to acidification differently, and defining spe...
