Phylum arthropoda is characterized by their exoskeleton, or "wearing" the anatomical compoent providing structure on the outside; whereas chordates usually have an internal skeleton or at least a notochord. Chordates like fish, birds, amphibians, reptiles, mammals are recognizable by having some kind of spinal column. (Chordates without a formal backbone still would not have an exoskeleton like the arthropods).
Chemical differences are also apparent, the bulk of arthropod skeletons are made from proteins including the tough long-chain polymer chitin, whereas chordates usually employ bones made from mineral compounds like those of calcium and phosphorus.
Wht is the difference between Lanthanides and Actinides?
what is the difference between 201 and 201K
difference between hand drawings and digital art
All legged arthropods have joints. Since arthropods have rigid exoskeletons, some degree of articulation or jointing would be essential else locomotion would be impossible. To provide the degrees of freedom necessary for effective locomotion, multiple joints per leg are necessary. The strategy varies somewhat from species to species in terms of the type and number of joints and length of each segment depending on the degrees of freedom required for each particular organism.
All buildings are structures but not all structures are buildings

isopod is a exopod
There is no inherent physical difference between a Hindu and a Muslim skeleton. Both belong to the same human species and have the same skeletal structure. Religious beliefs do not affect the physical characteristics of a person's skeleton.
I do not know to be honest, sorry.
An arthropod infection is normally linked to infections as result of a bite from a tick. A mycotic infection is a disease caused by a fungus.
the shark has a bigger nose and a tail.
The notochord of a vertebrate differs from that of an invertebrate because a vertebrates eventually turns into a back bone. Invertebrates just disappears.
Skeleton refers to the bones of the whole body; skull refers to the bones of only the head.
Snakes have a skeleton - worms don't.
by looking at the skin
A grasshopper's skeleton is on the outside, yours is on the inside. Also, his is made of chitin and your is made of bone.
In animals with endoskeletons, muscles surround the skeleton. In animals with exoskeletons,the skeleton surrounds the muscles.
