What is the phylum mollusca?
Some examples of molluscs are snails, squids, octopuses and clams (gastropoda, cephalapoda, and bivalvia, respectively).
There are a total of 8 lineages, but contain many species. They have fleshy bodies typically enclosed within a hard shell, with three segments: a head-foot, a visceral mass, and a mantle.
Some are hermaphroditic, however most are reproduced via sexual reproduction, with either internal or external fertilization.
If you're interested in more information about the phylum, here's a great website :)
If you'd like to know more about any of the specific classes, feel free to ask! I have more notes from my course this past semester notably about bivalvia, cephalapoda and gastropoda, courtesy of my professor that really enjoys taxonomy. Good luck!
