But do all turtles have shells, are there any species out there that don’t have any kind of shell? To find out the answer to this question I decided to do some research, and after a few weeks I finally found out the answer, here it is.ĭo turtles without shells exist? No, all existing turtle species have a type of shell. The type of shell turtles have is unique to them, and it’s also the reason why we can easily recognize a turtle when we see one. The shell of a turtle is what sets it apart from every other animal.
