Fishers in Naguabo, Puerto Rico help begin the queen conch life cycle in the hatchery.
Here you can see the tiny, unhatched queen conch eggs nestled between grains of sand.
The cells begin to divide inside the eggs. In these photos, you can see two cells become four.
When the eggs are ready to hatch, the embryos have a shell, velar lobes, eye spots and an orange foot.
They use their lobes to swim around as soon as they hatch.
They use their lobes to move, breathe, and feed on microalgae.
On day two, they begin to develop four lobes.
Ten days after hatching the veligers have six full lobes.
The lobes continue to elongate, the shell grows longer, and the foot changes shape.
The metamorphosed conch will feed on flocculated microalgal cells in the nursery.
