Egg: This egg has only been recorded once, but is included here as it appears distinctive (A). The oil globule is rendered brown, centrally, due to the dense cluster of black pigment below the yellow (A). The large oil globule, relative to egg diameter (30%) is also unusual.
Larva: As illustrated. B: 1 day, C: 2 days, D: 3 days (23°C).
This egg was only seen once off Park Rynie, on 28 October 1999. It was assumed to be an ambassid (possibly washed out of a local estuary), of which only A. natalensis and A. productus are potential candidates. Identification must await collection of specimens for DNA barcoding.
