Question

how is tortoise shell useful to it​

Answer 1

$\huge\boxed{\mathcal\red{Answer:-}}$

• The shell of the turtle is an important study, not just because of the obvious protection it provides for the animal, but also as an identification tool, in particular with fossils as the shell is one of the likely parts of a turtle to survive fossilization.

Answer 2

• The turtle shell protects the ventral and dorsal sections of turtles  by entirely encapsulating all of the turtle's critical organs, including the head in some situations.
• It's made up of ribs, pelvic bones, and other bones common in most reptiles that have been changed.
• The shell's bone is made up of both skeletal and dermal bone, indicating that dermal armour was most likely incorporated into the rib cage to complete the shell's enclosure.

• Tortoise shell has traditionally been utilized as a decorative gem material in art, jewellery, and personal things like combs and eyeglass frames.
• Tortoise shell has been used by humans for thousands of years, but its popularity peaked in the 18th, 19th, and early twentieth centuries.
