Illumise doesn't evolve at all...
They all evolve at different levels
a stone onix will evolve into a stone steelixs?
yes
It Doesn't evolve. It's an all-round good Pokemon, i like to think of it like Gyarados' little brother.
all vertebrates are chordates because vertebrates are the sub- group of phylum chordates and also it follow one of the important feature of the chordates i.e. presence of notochord whereas all chordates are not vertebrates because some chordates are cephalochordates, urochordates.
One characteristic shared by all chordates is the presence of a notochord, a flexible rod that provides structural support. Humans, being classified under the phylum Chordata, possess a notochord during their embryonic development that eventually develops into the spinal column.
Yes. All chordates are coelomates.
There isn't a "popular name" for them. The most familiar chordates are the vertebrates, but not all chordates are vertebrates (tunicates, for example, are chordates).
nerve cord runs down the back of ALL chordates
All fish are chordates. Chordates are vertebrates that have a hollow dorsal nerve called a notochord. They also have a central nervous system and gill clefts.
a backbone
Well, no they don't... There's a group of chordates called Agnatha which basically contains all the jawless chordates. And there are obviously limbless chordates present, the fishes and the snakes being the most well-known of the examples...
At some point in all chordates' lives, they have a notochord, a nerve chord, gill slits and a tail. Some chordates are more complex though.
All Chordates have(in part of their life or another) A Notochord A hollow dorsal nerve cord A post-anal tail
Yes, most chordates are vertebrates.
Vertebrates are a subgroup of the chordates, meaning that all vertebrates are chordates, but not all chordates are vertebrates. Vertebrates are distinguished from other chordates by having backbones or spinal columns.All vertebrates have muscular systems that mostly consist of paired masses, as well as a central nervous system which is partly located inside the backbone (if one is present). The defining characteristic of a vertebrate is considered the backbone or spinal cord, a brain case, and an internal skeleton, but the latter is not true for lampreys, and the former is arguably present in some other chordates. Rather, all vertebrates are most easily distinguished from all other chordates by having a clearly identifiable head. Sensory organs--especially eyes--are concentrated at the foreend of the body, and there is pronounced cephalization.
