The word vertebrae actually means back bone. so a vertebrate has a back bone, like most mammals, and invertebrate means the animal has no backbone, like insects, crustaceans, and jellyfish
The word invertebrate means with no backbone, whereas vertebrate means with a back bone. People and most animals are vertebrates and most Spiders and insects are invertebrates.
Vertebrate animals have a spine
Vertebrates have spinal chord and invertebrates don't.
You do know that humans and hamsters aren't the same, right?
The most significant difference between a vertebrate and an invertebrate is that a vertebrate has a spine and an invertebrate doesn't.
The notochord of a vertebrate differs from that of an invertebrate because a vertebrates eventually turns into a back bone. Invertebrates just disappears.
Land and aquatic vertebrates are similar in that they both have a vertebral column. They are both either primary or secondary consumers as well. A difference is that vertebrates that live only in the water do not have fully developed hind legs.
The most obvious way in which mammals differ from the other four classes of vertebrates is that mammals nurture their young on mothers' milk.
Their skeletons tend to be on the outside
Arthropod skeletons differ from ours in that they are external, or exoskeletons. By contrast ours are internal, or endoskeletons.
An invertebrate does not have a backbone.
Vertebrates have backbones, other animals (besides vertebrates) don't have back bones.
testosterone and estradiol have different functional groups attached to the same carbon skeleton .. hope this helps!
vertebrates differ from other animals because they have a central nervous system running down their back
