Long sperms with a long history: Reproduction in non-marine Ostracoda (Crustacea)

Spermatozoa of non-marine ostracods are among the longest known in the animal kingdom. Their morphology is outstanding, and reproduction with such sperms requires a variety of anatomical and behavioural adaptations. Can this system persist over geological time scales? Only exceptionally preserved fossils can tell us more. We dive into what is known about the history of ‘giant ostracod sperms’ through rare fossils with soft part preservation.
