Predators. The main benefit of wearing a shell is that is helps protect turtles from predators. Made from bone covered by hard plates called scutes, the shell makes it difficult for many predators, such as raccoons and otters, to get a bite of tasty turtle meat.

What is the purpose of a seashell?
seashell, hard exoskeleton of marine mollusks such as snails, bivalves, and chitons that serves to protect and support their bodies. It is composed largely of calcium carbonate secreted by the mantle, a skinlike tissue in the mollusk's body wall.
How does a shell help a sea turtle?
The benefit of a turtle's shell is clear. It's armor that moves with turtles and protects them from animals that want to make them lunch. ... This is important because, unlike other creatures with hard exteriors, like armadillos, a turtle shell is actually part of the bone structure of the animal, not scales.
What is the function of shell on the body of a tortoise?
Form and function. The turtle's shell is an adaptation that protects it from predators, which compensates for the reptile's slow crawling speed. The carapace and plastron each arose from two types of bone: dermal bones that form in the skin and endochondral bone (bone arising from cartilage) derived from the skeleton.
Can turtles live without their shell?
The answer is no! They likely could not survive a couple minutes or even seconds without it. A turtle's shell includes bones and nerve endings that it needs to live and function. The shell is an important part of a turtle's anatomy which includes their rib cage, spinal cord, and nerve endings.
What is in a shell?
Shells are made of calcium carbonate, in the mineral form of calcite or aragonite. Animals build their shells by extracting the necessary ingredients—dissolved calcium and bicarbonate—from their environment.
How does a shell grow?
Mantle tissue that is located under and in contact with the shell secretes proteins and mineral extracellularly to form the shell. ... Thus, seashells grow from the bottom up, or by adding material at the margins. Since their exoskeleton is not shed, molluscan shells must enlarge to accommodate body growth.
What do sea shell eat?
Some do feed on fixed animals (sponges), on algae, on grass, on other marine gasteropods, on worms, on fishes, on dead animals (necrophagous shells). Cone Shells are predators and their feeding habits are complex.
What is in a tortoise shell?
The whole shell of the tortoise is made up of numerous small bones which are covered by separate plates of keratin called scutes. As a tortoise grows, extra layers of keratin are added underneath the existing layer, causing “growth rings”.
Do tortoises feel pain in their shells?
The shell's top is called the carapace, and the bottom is the plastron. Turtles can feel pressure and pain through their shells, just as you can feel pressure through your fingernails.
What is tortoise shell called?
Normal Shells
Turtles and tortoises have a carapace (the top or dorsal shell) and a plastron (the bottom or ventral shell), both of which should always be hard (unless it is a hatchling turtle or a species of water turtle that always has a soft shell).
Why do turtles lose their shell?
Why Do Turtles Shed Their Scutes? Healthy shedding occurs as part of a water turtle's normal growth, as the shell expands with the rest of its growing body. Other common reasons for shell problems include bacteria, parasites, algae, environmental issues, and poor nutrition.
How do turtles make their shells?
Much like our bones, the primary mineral in a turtle shell is calcium phosphate. Turtle embryos develop shells through the fusion of rib bones and back bones. The upper portion of the shell is called the carapace and the lower portion is called the plastron.
What happens if a turtle loses its shell?
A broken shell isn't an immediate death sentence, but it is a very serious medical condition. A crack or break in a shell means the turtle's or tortoise's body is opened up. ... Poor diet and unsanitary tank conditions can cause ulcers on and around the shell. This is called “shell rot” and it can be deadly.
