Egg: This egg has been seen so seldom, and it is so like KIIIA4 in size of egg and oil globule, that it has not been recognised as different, until hatched. Thus it has not yet been photographed.  The egg and embryo have an amber hue, but the oil globule is clear. Pale yellow pigment develops on the late embryo. There is no yellow pigment on the yolk (compare with LIIIC9). Incubation is about 30 hours.

Larva: The pattern of yellow pigment, elongate body, moderate gut length and high myomere count, set the 1-day larva apart from all except LIIIC9,

but the latter has a more even spread of earlier developing finfold pigment. B: 1 day, C: 3 days (24°C).

The similarity to LIIIC9 suggests this may be a Pseudorhombus, and the larva in B1 of LIIIC9 might be the early larva of this species. No larval DNA barcodes are currently available.

The few collections made of this egg point to a spring spawning season (blue graph). It was also seen twice in the DHM samples, in spring and early summer (green graph). Only 16 eggs have been seen in linked samples, of which, 15 were in offshore samples.
