Egg: The egg yolk is misty, has a strong circular segmentation, and from 5 to 20 oil globules, clustered together, usually light amber. On two occasions the egg was described as slippery. Incubation is 90-95 hours (22°C).

Larva: The newly hatched larva has an unusual pattern of pigment in the finfolds (B, B1 & B2). Eyes and mouth are undeveloped. The 4-day larva is shown in C. B: 1 day, C: 4 days, (22°C). A myomere count is not yet available for this larva.

No attempt was made to rear this larva. The egg was last seen in 2003; thus a specimen has not been collected for DNA barcoding.

This egg is rare in the Park Rynie samples, and when seen, it is usually only one or two. No specific spawning time is apparent from the graphic (blue graph). They were not encountered in the DHM samples. The annual trend plot is shown (white graph). In the Park Rynie linked samples, the eggs were mostly taken offshore, but the numbers are too low to be useful.
