Egg: Although these eggs normally have oil globules widely distributed in the yolk (A), occasional eggs are seen with one oil globule when about to hatch (B). At this stage the yolk is misty. Incubation is >72 hours. When single, the oil globule is amber and measures 170-195µm.

Larva: The early larva is lightly covered in fine white spots (C), which persist to 5 days, while the larva turns brown (D).  C: NH, D: 5 days, E: 150 days (24-26°C).

Five of these larvae have been barcoded, and match the barcode of 3 locally collected adult Kentrocapros rosapinto(BOLD).


This egg has only been seen on 10 occasions off Park Rynie (blue graph), each as a single egg, and 8 were in offshore samples.
