There are three main subclasses of gastropods; the Prosobranchia (ocean snails), Opisthobranchia (sea slugs, sea butterflies and sea hares), and Pulmonata (land and freshwater snails and slugs). Each of the subclasses has evolved in their own way and members differ in their reproduction and life cycles within the subclasses. The gastropod folks are so large it really is impossible to spell out living cycle of each one individual species, but a majority of general rules do apply. The more evolved the species, the more complex their reproductive cycle in addition to their biology. Here we will look at the life span cycle of a gastropod through various examples and how they differ with regards to the type. Let's now explore this window further to find out when was the best time.The egg once released have a lifespan of twelve (12)hours. The egg therefore, needs to be fertilized in this twelve- hour period for conception to occur. The sperm on the other hand can survive as much as 5 days in the reproductive duct. 2. Start a program.
