Egg: The early egg of this species has a distinct red sheen to the chorion (A). The late embryo and yolksac are covered in white pigment spots (C). Incubation is 70-90 hours. One specimen was seen with a single, amber oil globule of 215m..

Larva: The early larva is covered in fine white spots (D), which persist to 5 days, when the larva turns blue-grey (E), and to 7 days, when the larva is dark above and yellow below (F & G). D: NH, E: 5 days, F: 6 days, G: 7 days (24C).

Shao et al (2001) show Diodon holocanthus as having an egg of this size. Six larvae have been sequenced, and they match a D. holocanthus adult sequence in the BOLD Archive. No locally collected adult fish have been barcoded.

Like MIA1A, this is a summer spawner in the Park Rynie area (blue graph). The Park Rynie linked samples had more eggs inshore (58%), but numbers are low. See Section 7.3 and Table 1 of the Introductory Notes, for more information on the linked samples
