Banana Slug Crawling at Samuel P. Taylor Park. In order to hatch, the eggs need sustained moisture, mild temperatures, and a good hiding place. Once the eggs have hatched, it is up to the baby banana slugs to find their own food for survival. Predators like to eat banana slugs at all stages of their lives. A high number of eggs hopefully ensures the survival of the species, even though they have a high mortality rate.
Banana slugs have a high growth rate, which also helps to maintain a stable population.
They also concluded that banana slugs are able to endure longer periods of intense weather as compared to the Arion ater slug. They attribute this to the large surface area to volume ratio which causes less evaporative stress. The banana slug is a mollusk, which came from the sea. Their stages of evolution can be seen in other various species of land and sea mollusks. The tremendous adaptation variation in slug traits such as size and color, make their fossils challenging to classify.
