Reproduction Oval sperm platelets observed in coelomic smears from a few large specimens (20 mm or more in length). Individual sperm with a short oval nucleus, a middle piece consisting of 2-4 smaller spherical structures that are likely mitochondria, and a long tail or flagellum. Development of post-larvae and juveniles described by Blake (2015: 70-71, figs. 4-5).  [details]
