Yes, they do. Whales are marine mammals, and all mammals are vertebrates.
Why was the evolution of jaws an important event in vertebrate history?
The evolution of jaws is believed to be used originally for respiratory purposes. However, it is important to the history of vertebrates mainly because it allowed for more efficient eating.
Do the vertebrates have brains?
That would depend on the animal. Practially all vertebrates have brains, with mammals' and perhaps birds' being the most complex of all. For invertebrates, it depends on the species. Arthropods and cephalopods tend to have brains. Sponges have no neurons whatsoever.
Yes. They have a spinal column, which classifies them as Vertebrates.
Are mammals the only animals that have backbones?
No! Fish, reptiles, birds, and amphibians all have backbones, but are not mammals.
Is a shrimp a vertebrate or an invertebrate?
The shrimp is an invertebrate. It is supported by its shell, which is an exoskeleton. It does not have any bones inside of it.
What problems were associated with colonizing land during the evolution of vertebrates?
1) Animals needed to withstand the effects of gravity.
2) Animals needed to reduce desiccation (the loss of water).
3) Animals needed to have a mode of transportation.
4) Animals needed protection against UV rays.
5) Animals needed to reproduce without water.
6) Animals needed to breathe air.
7) Animals needed to adjust their senses to life out of water.
What are the layers that make up the wall of the vertebrate gastrointestinal tract?
Though slightly variable, from outside to inside it lies as serosa, muscularis, submucosa and mucosa.
What is the realtioship between vertebrates and evolution?
Well, vertebrates evolved from non-vertebrates if that's what you mean.
Yes, nutria rats are mammals and all mammals are vertebrates (they have a backbone).

What animal was called I don't know by the aborigines?
I believe that this is the kangaroo.
"kanguru" supposedly means "I don't know" in the Aborigine language. When asked what the name of a Kangaroo was, this was the alleged answer. Whether the Aborigine in this story did not understand the question or was simply making a joke at the enquiring white man's expense can not be known for certain.
all chordates have notochord, gill slits, postanal tail, and nerve chord.
