Crabs grow by molting, which involves shedding their old exoskeleton and forming a new, larger one. This process is essential because their hard exoskeletons do not expand, so molting allows them to grow.
After molting, crabs are highly vulnerable as their new exoskeleton is soft and takes time to harden. During this period, they often hide to avoid predators.
Crabs have the ability to regenerate lost limbs. If a crab loses a claw or leg, it can grow a new one during subsequent molts. This ability helps them survive injuries from predators or fights.
Some crabs can change color to blend in with their surroundings, providing camouflage from predators. This change is often influenced by the environment, diet, and hormonal changes during molting.
Each time a crab molts, it can increase in size by as much as 15-25%. This significant growth allows them to become stronger and more capable of defending themselves and finding food.
