Which of the following organisms lays its eggs in water?

While ducks are waterfowl and often found in aquatic habitats, they typically lay their eggs on land, in nests made from vegetation. The eggs are laid away from direct water exposure, even though the ducklings may eventually enter the water shortly after hatching. Thus, ducks do not lay their eggs in water.

Raccoons are terrestrial mammals that primarily construct their dens in trees, burrows, or under structures. They lay their eggs in hidden spots on land, not in water. As omnivores, their reproductive behavior is adapted to terrestrial environments, making them unsuitable for laying eggs in aquatic settings.

Sea turtles do come ashore to lay their eggs, but they do this on sandy beaches rather than in water. The female sea turtle digs a nest in the sand, deposits her eggs, and then returns to the ocean. The eggs incubate in the warmth of the sand, and the hatchlings emerge to make their way to the sea.
