Animals that possess exoskeletons are limited in the maximum size they can reach. As an animal gets larger its shell must increase in size in order to support its weight. This causes the surface to volume ratio to decrease. As this ratio decreases, it becomes more difficult for the animal to obtain enough oxygen for cellular respiration and space for internal organs is also lost with a thickening shell.

Why do animals having exoskeleton not grow in size?
animals do not have exoskeletons they have an inerskeleton like us. they are mammals.
Why do animals moult their exoskeleton as they grow?
having an exoskeleton affect how an animal grows because the exoskeleton does not grow as the animal grows so the animal must shed or molt its exoskeleton.
What are three characteristics common to all animals in the arthropada phylum?
The three common characteristics of animals in the phylum Arthropoda are: having a segmented body with paired jointed legs, having a hard exoskeleton made of chitin, and undergoing ecdysis, or molting, to grow.
How does the animals with skeleton external grow?
An animal (insect) with an exoskeleton still grows under its exoskeleton like any other animal (insect). The exoskeleton is like a suit of armor, when the animal (insect) grows to big to fit inside its exoskeleton it sheds it, and a newer exoskeleton will grow to fit the animal (insect).
What are pros and cons having a exoskeleton?
Pros: It is literally a suit of armour - its tough, heavy and long-lasting.Cons: One can't really grow in such a rigid frame; in addition, having an exoskeleton may restrict certain things such as breathing - it means that you can't have lungs because they expand, but the exoskeleton will prevent this.If this answer is good, please rate it :)
Why don't all animals have exoskeletons?
Only bugs and spiders have exoskeleton. Imagine being as small as a ant. You can't fit many bones in your body then. So bugs and spiders have exoskeletons. Also, because they need a lot more room for all of the air ways in their bodies.
Does a scorpion have an endo skeleton?
No, scorpions do not have an endoskeleton; they possess an exoskeleton. This hard outer structure, made of chitin, provides protection and support for their bodies. Unlike animals with endoskeletons, scorpions must molt, shedding their exoskeleton to grow.
Why do some animals shed their skeletons?
Only animals with an exoskeleton such as insects shed it. They usually don't grow with the animal, so it simply has to shed it and make a bigger one for itself as it matures.
What is molting and why important to animals?
Molting is the process in which animals shed their old exoskeleton or feathers and grow a new one. It is important for animals as it allows them to remove damaged or worn-out body coverings, accommodate growth, regulate body temperature, and avoid becoming trapped in their old exoskeleton.
What do you call it when a bug sheds its exoskeleton?
An insect does this to grow. It expands rapidly before the next exoskeleton hardens.
Why do arthropods undergo molting as part of their life cycle?
Arthropods undergo molting to grow because their exoskeleton does not grow with them. Molting allows them to shed their old exoskeleton and grow a new, larger one.
How does an arthropod grow larger?
Through shedding their exoskeleton.
