dc.description.abstract |
In the family Asterinidae, development through a planktonic lecithotrophic brachiolaria larva is common and has evolved independently several times. Here, we describe the lecithotrophic development of the asterinid Stegnaster inflatus, a species endemic to New Zealand. Early development through the blastula and gastrula stages is short, with hatching at the brachiolaria stage occurring within 48 hr. After hatching, larvae are negatively buoyant, and without aeration remain near the bottom of the culture containers. The settled benthic juvenile stage was reached in ~2 weeks. The brachiolaria of S. inflatus shares common characteristics with the planktonic brachiolaria of other asterinids in that the brachiolar attachment apparatus comprises three brachia and a central adhesive disc, although the latter is thin and appears to be reduced. Mortensen (1925, Videns kabelige Meddelelser fra Dansk naturhistorisk Forening i København, 79(15), 261-420) had hypothesized that individuals of S. inflatus might brood within the “cave” formed in the interambulacral space between the arms. We found no evidence for brooding, but hypothesize that S. inflatus may have demersal development, on or near the bottom, which has implications for larval dispersal and population structure. |
