Limpet Babies: Siphonaria limpets lay eggs in circular or coiling jelly-like masses that contain thousands of eggs suspended in a gelatinous matrix, attached to a hard surface. The free-swimming limpet larvae have a little spiral shell like other 'normal' snails. As they develop, the shell flattens and becomes umbrella-shaped.
