As apple snail veligers grow and develop, they gradually lose their velum and begin to crawl along surfaces using their muscular foot. They also develop a longer, more pronounced siphon, which they use to breathe air and extract oxygen from water.
The appearance of apple snail hatchlings can vary slightly depending on the species, but they generally share the characteristics described above. They are small, transparent, and have a delicate, fragile appearance. As they grow and develop, they will take on the coloration and physical features of their adult counterparts.
