However, it was really cool to watch the larva retracting its foot and velum and closing its operculum (trap door) to seal itself into its shell. Then after several seconds, it would use its foot to push its operculum open, and evert its foot and velum. I took a series of pictures showing the veliger slowly evert its foot and part of its velum from the shell. Each picture also shows the hexagonal honeycomb-like texture of the shell, which I think looks cool. These larvae are fun to watch and I look forward to observing the continued development of my Calliostoma culture. See more pictures of Calliostoma veligers.
