Chitons have a tail shell which is made of eight separate shell plates or valves. The plates overlap but are articulated, providing protection but allowing freedom of movement.
The red-bellied turtle actually has a hard shell, as do all turtles. The shell of a turtle is made up of bony plates covered by a layer of keratin. This shell provides protection and support for the turtle's body.
Yes they have a backbone. You can't see it because of his shell that protect them. Thanks!!
Turtles are "born" with a shell. In the first days after hatching the shell can be softer, because their bones are not calcified all the way yet. Once fully grown, turtles and tortoises have hard, protective shells that are made up of 59 to 61 bones covered by plates called scutes. The scutes are made of keratin, the primary substance in hair, nails and hooves of other animals, but the turtles shell is part of its skeleton. And like bones, it grows with them while they age.
The shell covering the top of a turtle's body is called the carapace (say karra-pace).It is made of a hard substance called scutes.Some turtles do not have a hard carapace. The carapace of soft-shelled turtles and the leatherback turtle is made of thick skin.The shape of a carapace is not always the same:
Well, The shell is rather quite fragile but the shell is a little hard.
chitons
Members of the class Polyplacophora are known as chitons. They are characterized by their shell, which is divided into eight separate dorsal plates or valves. These plates are made of aragonite, a type of calcium carbonate.
Chiton possess a highly conserved skeleton of eight shell plates (valves) surrounded by spicules or scales
scute
tectonic plates
Tectonic plates
There are 41 minor plates so good luck with that
All eight: the shell is full.
These are the noble gases which have a complete valence shell.
I( think they are called scuta
The second shell can hold eight electrons.
Helium is the only noble gas that does not have eight electrons in its outer shell. It has only two electrons in its outer shell.
