There are a lot of snails where I live at the moment, some have a shell while others don’t! I don’t know how they acquire their shell, what it is used for, and why some don’t have any.
In: Biology
Snails grow their shells by secreting calcium carbonate; so they don’t “get” them like a hermit crab would get a shell, rather they’re a part of the creature itself. Much like turtles and tortoises too – they’re all joined and now I have no idea how much more text I need to write to let this comment not get automodded for being too short and simple!
