Why is a large heavy exoskeleton less limiting for arthropods that live in the water?
that is not the answer!!

Why can't arthropods be large?
Their exoskeleton limits growth; if arthropods were large, their armour would be too heavy and they'd collapse! Also they use trachea to absorb oxygen, and if they were large, these wouldn't reach through their entire body and cells would die off in areas further away from the oxygen supply. This is why they did get large in the Carboniferous era, when oxygen concentrations in the atmosphere were much higher. :)
Why do arthropods need a hard exoskeleton?
Firstly, any sizeable organism be it Arthropod or otherwise would need some kind of infrastructure if it's important to that organism to maintain a consistent general body plan or morphology. Not all organisms require this; for example there are amorphous organisms like the amoeba or certain fungi; some slime molds can grow to a significant size and survive quite well with a highly generalized and nonspecific shape. In the case of those with a high degree of motility, some consistency in shape is useful. Even jellyfish with no significant skeleton, have sufficient rigidity for mobility. The important thing is, the degree of infrastructure is consistent with the habitat and behaviors to which it's adapted. In the case of arthropods, an exoskeleton is very convenient and an endoskeleton would be redundant; for vertebrates, an endoskeleton serves this role and an exoskeleton would prove cumbersome. To be sure, some vertebrates evidence similar adaptations for which an arthropod uses an exoskeleton, for example, the plating on an armadillo, the shell on a tortoise, the thick skin on large mammals, etc; yet for their mass, the thickness of an exoskeleton to provide the necessary rigidity for the purpose of the body plan in vertebrates would be impractical. The reverse can be said to be true of some arthropods; since some have muscles which anchor not to the exoskeleton but to internal cartilaginous structures which are arguably somewhat endoskeletal. One might say, the laws of physics, particularly mass and gravity, dictate the usefulness of an exoskeleton to Arthropods given their size, role, and adaptations; the hardness of it reflecting the requirements placed upon the organism for its functionality and thus, its survival.
Is a sponge an arthropoda?
Arthropods and sponges are two major divisions in taxonomy called Phyla (singular, phylum). Phylum Arthropoda ("joint appendages"), or the arthropods, includes such creatures as insects, spiders, millipedes, crustaceans, etc. Phylum Porifera ("pore-bearing") are the sponges.
What is the habitats for arthropods?

What different kinds of appendages do arthropods have?
This large phylum includes classes as wide and diverse as: arachnida, insecta and crustacea. The appendages that can be seen in these classes include: jointed legs, antennae, mandibles and maxillae, although each class is more specific.

Are butterflies arthropods?
Yes, butterflies are arthropods. Arthropods are a large group of invertebrates that includes insects, spiders, and crustaceans, among others. Butterflies belong to the class Insecta within the phylum Arthropoda.
Why can't invertebrates get very large?

How many body segments does arachnids have?
For a spider: Large frontal exoskeleton, large rectal exoskeleton, eight legs, and then their pincers at the front. Scorpions are similar, but they have a stronger exoskeleton and a tail leading on from the rectal exoskeleton. Their tail is split into roughly 10 segments, but it varies between species.
What does athropodes mean?
Arthropod is from Modern Latin for 'jointed feet'. The creatures so-named are also distinguished by jointed legs, segmented bodies, and exoskeletons made of chitin.

Why is a large excoskeleton less limited for arthropods that live in water?
three paits of jointed legs. Edit: Be Real Man. The real answer is that the water pushes heavy stuff up to make them lighter in water then in land. edit: really you both are rong the real answer is:Afaik this depends on the animal in question. Some insects, for example, do not grow in size at all when adults and thus avoid this problem. Animals that do shed their exoskeleton can move, the underlying soft exoskeletong along with the internal pressure of the animal are enough to facilitate this. But at least many crayfish (and likewise many otehr arthropods that shed their exoskeleton) hide until their exoskeleton has hardened again - that is, they can move, but will not unless they really have to. They just hide in some nook and wait. And what comes to other disadvantages of chitious exoskeleton: it allows muscles to attach only inside of the exoskeleton, quite unlike human muscles for example work. This provides poorer strength production, which is why arthropods cannot really grow much larger than what we see around us. For similar reasons, virtually all the largest arthropods live in water, because there you need less strength to move heavy weights. Even though we know that ants are mighty strong compared to their size, human-sized ants would collapse even udner their own weight and they could not carry a hundred or so times their weight like small ants do!
What are the seven structures or physiological patterns that make the arthropods so successful?
Hardened Exoskeleton Jointed Appendages Modified Segments Respiratory Structures Sensory Specialization Specialized Stages of Development Large in abundance and diversity
Is a scorpion a mollusca?
No, molluscs have their own separate phylum (Mollusca), different in characteristics from arthropods. Mollusca includes snails, cuttlefish, and limpets. Note that the term 'anthropod' should not be confused with 'arthropod' - anthropod is not a phylum nor taxon but is a general term meaning human or humanoid.
What is a crayfishes protection?
crayfish have a hard exoskeleton and large, pinching claws.
