Nature has given every being a feature that protects them from predators. Some animals have agile muscles for escaping, whereas some have quills to scare off their attackers. One such defensively gifted creature is a turtle. Their shells are extremely tough shields that are impenetrable for predators to break.

So, how strong is a turtle shell? Turtles have a tough shell that can withstand 200 times its own weight. This means that 1000 pounds of pressure won’t be enough to break a turtle’s shell.

So what makes these turtle shells tough? Let’s dwell further.

What Makes A Turtle Shell Hard?

A turtle shell is made up of keratin, the same element that makes up our nails and hairs. The top part of a shell is called a carapace, and the bottom part is called a plastron. Both the Plastron and Carapace are made up of keratin plates which makes the turtle shell tough.

On the surface of these shells, there are hard scales known as scutes. Scutes protect the turtle from getting scratches and bruises.

Plastrons are flat in structure and protect the turtle when predators topple them upside down, in addition to shielding the internal organs.

Can A Turtle’s Shell And Its Body Separate?

No, a turtle’s shell and its body are not separate. Unlike the turtles in cartoons, turtles cannot be pulled out of their shell. Shells are connected with their ribs, spine, and several other internal body parts. So, a turtle’s shell and its body cannot be separated. 

How Much Force Is Required To Break A Turtle Shell?

Turtles shells are sturdy enough to withstand extreme pressure. Different species of turtles have different degrees of hardness in shells. It’s believed that a turtle shell can resist up to 200 times its weight. So, a 1000 pound of pressure might not be enough to break a turtle’s shell. 

As I have said, different turtles’ breeds have different degrees of hardiness. Sea turtles have a softer shell compared to freshwater turtles. So, a strong bite from a shark can break a sea turtle’s shell.

Is Turtle Shell Bulletproof?


Even though a turtle’s shell is one of the most formidable defensive covers, some animals can break them, especially the predators. Crocodiles, hippos, and even some birds are known to do so.

Here are some of the animals who can break a turtle’s shell.

Crocodiles And Alligators

Crocodiles and alligators have powerful jaws that can break even the sturdiest of turtle shells. And turtles are prey to these reptilian predators. 


It may come as a surprise to you, but the hippopotamus has more biting power than crocodiles. So a single bite can break a turtles shell if caught between the jaws of a hippopotamus.

But the good news is that hippopotamuses are vegetarians and won’t attack turtles unless agitated or encroached.

Sharks and Whales

Turtles in the sea are prey to sharks and whales. Moreover, the shells in marine turtles are softer than the freshwater turtles. Sharks have one of the most potent bite forces among sea predators.

Their jaw power can easily crush the turtle’s shell underwater. So, it is no surprise that turtles are one of the tastiest prey for sharks and whales. 


Birds like eagles and vultures have keen eyes when searching for prey, and turtles make wholesome food for them. These predator birds have sharp beaks, which they use for gnawing meat.

However, brute force alone isn’t enough for them to break through the turtle’s hard shells. 

So, using their intelligence, these birds will grab a turtle with their claws and take it to a greater height. Once they reach up in the clouds, they will drop turtles over the rocks, which will break the turtle’s shell. 

Honey Badgers

Honey Badgers are one of the fiercest animals who are natural predators to turtles and tortoises. Their bite force with sharp teeth can crush a turtle’s shell after just a few bites.

Can Turtle Shell Grow Back Regrow?

A turtle’s shell can heal after slight fractures, but they cannot regrow their shell once it’s completely broken. Irrespective of the severity, a broken turtle shell should always be first assessed by a vet before you proceed with any treatment.

Final Words: How Strong Is A Turtle’s Shell?

Although the shell protects a turtle from several predators, these shells aren’t unbreakable. Factors like inappropriate habitat, a deficit in nutrition, lack of vitamin D, and sunlight can gradually break their shell. Along with that, predators like crocodiles, alligators, and sharks can crack their shells. If you are keeping a turtle in the tank, you need to provide him with a proper diet and adequate space for basking under the heat lamp.
