Is this a Hypselodoris bullocki.? I have never seen this nudibranch before, but I noticed it twice today, on 2 very seprated reefs. They were both extremely small less than 1cm. Does that mean they have recently hatched, and is this seasonal.

This is Thorunna horologia, a small chromodorid which doesn't grow much larger than a 10-15 mm. This animal has only been reported from Tanzania and northeasten South Africa, and then very rarely, so we can't say much about its biology and we certainly have no idea of its life history. Like many small nudibranchs it probably only lives a few months.
