Giant African Land Snail (Achatina fulica)
Of all Mollusca, the most research has been done on the category that includes snails and slugs. The giant African land snail is a perfect example of the form and functions of the Mollusca at work. The cerebral ganglion, or brain, of the species is responsible for secreting a neurohormone. This neurohormone is sent to the hermaphroditic gonad, which is a gland that has both the male and female reproductive systems included. Most, if not all, snails are hermaphrodites, which means that they are both male and female. The gonads that lay eggs are isolated from the male reproductive systems in the Mollusca. This hormone is stored in a typical organ until used.The gonad also secretes testosterone, which allows the snail to reproduce as a male as well.
This gland affects the mating patterns of these animals as well. These snails are known invasive species in the US.
FUN FACT: This species of snail can grow up to 8 inches long!
