fish represent three of several classes that make up the phylum of vertebrate
They have shells.
Sharks are a type of cartilaginous fish, that is their skeleton is made of cartilage rather than bone. They belong to the vertebrate subphylum of chondrichthyes.
Sharks belong to the vertebrate group known as Fish. Specifically, they belong to the vertebrate group known as Chondrichthyes - all sharks and rays - which have skeletons of cartilage rather than bone.

The answer would be fish as they are the simplest organisms listed and have been around the longest leading to many different species, much more than the others.
The three vertebrate classes of fish are: Agnatha (jawless fish without scales, e.g. lampreys and hagfish)Chondrichthyes (sharks and rays, which have skeletons of cartilage rather than bone)Osteichthyes (all the bony fish e.g. tuna, trout, whiting, etc.)
Yes.There are five vertebrate classifications: mammals, birds, amphibians, reptiles and fish. Fish are classified as fish because they have the following characteristics:breathe using gills rather than lungsa covering of scalescold-bloodeduse fins rather than limbs for locomotion
sometimes when a fish is stressed it can turn darker than usual. I f you see this take your stressed fish away from your other fish,which is causing it stress, into a different tank and leave to relax till it changes back to normal once it has you can move it back with the other fish
No other food than dead fish.
fish The vertebrates have a nebulous starting point. There are some chordates that have more of a notochord than a true vertebrate column. Some taxicologists are more comfortable saying that a Coelacanth has a notochord rather than a vertebrate column when clearly the vertebrate are present in this animal. So its is a matter of your own definition. One could say 'at a stretch' that the hagfish and lamprey are the most ancient vertebrates.
