Snail eggs

On the shores of lakes, attached to leaves and stems of plants, these snail eggs are pink, white, and some are slightly brownish. Their Latin name is Pomacea maculata, also known as the freshwater snail.

Female snails crawl up aquatic plants and lay their eggs there, adhering securely until they hatch. I haven't seen the exact moment the eggs hatch, but it's likely that the hatching eggs will fall into the water one by one and grow into adults.

I've also seen these snail eggs attached to other types of plants, but always to plants growing near water sources.
