Egg: This egg was consistently seen as depicted in A, with seven patches of yellow on the embryo, five in pairs from nose to oil globule, and 2 blotches in the tail. Sometimes only the first three are in pairs (B). Black pigment is seen under the yellow on a white background. The oil globule is clear. Incubation is 24-26 hours. Spawning seems to be confined to evening.

Larva: As soon as the yolksac is reduced, the slim shape of the larva is apparent (C). At two days the dorsal and ventral finfolds have formed a dense edge (D, black arrows), within which there are a few spiny serrations dorsally in the area of the posterior black arrow, and ventrally, just astern of the anus (D, white arrow). By day 4, the midtail blotch has disappeared, and the only yellow pigment is in the head and thorax (F).  B: NH, C: 36 hours, D: 2 days, E: 3 days, F: 4 days (23°C).

All attempts to rear this larva, failed.  No hatched larvae have yet been successfully sequenced, for DNA barcoding, so the identity is presently unknown.

This species had quite a long spawning period through winter and spring off Park Rynie (blue graph). It was only seen twice in the DHM samples, during May and November. The egg has been less abundant in samples off Park Rynie in the past few years (white graph). The Park Rynie linked samples showed slightly more eggs in the offshore samples (57%), but the percentage is lower than the two indicator species, suggests spawning is mainly in the 20-30m depth range. See Section 7.3 and Table 1 of the Introductory Notes, for more information on the linked samples.
