Egg: In early developing eggs, black stellate spots cover the yolk near the embryo, and laterally on the embryo. One egg collected with a thin embryo already formed (Plate A, right egg), took 9 days to hatch (23°C).

Larva: The newly hatched larva has pigmented eyes, and blue pigment dorsally (B). Enlarged pelvic fins can be seen in the 5 & 6 day larvae (C& D). B: NH, C: 5 days, D: 6 days (23°C).

Ikeda & Mito (1988) show two exocoetid eggs with no spikes on the chorion, Exocoetus volitans and E. monocirrhus, both of which occur in our waters. A larva has not yet come available for DNA barcoding.

This egg has only been collected on four occasions off Park Rynie, all in September to November (blue graph).
