Note
One specimen of the sand-burrowing nudibranch Armina tigrina Rafinesque was collected from South Carolina in June. The specimen deposited a single egg mass of approximately 6500 white eggs which developed into lecithotrophic veligers in 8 days at 23°C. Of the veligers which metamorphosed, 9 lived 4–5.5 months (i.e. the life cycle was subannual). Eight individuals reached sexual maturity in about 80 days.
