They are to hold the composure of the whole fish. Without the bones they'd just flop around and wouldn't be able to move.
They protect the dorsal neural chord characteristic of vertebrates
The bony part in the fish fin or tail is supposed to support the fin or tail.
A fish have 20 bones
Yes. One of the traits for something to be a "fish" is to have vertebrae. I believe that most, if not all, fish have backbones.
Yes, all fish have bones. In fact, all fish are vertebrates, so they all have vertebrae (a spine or backbone).
Jawless fish and cartilaginous fish have cartilaginous skeletons, and bony fish have skeletons made from bone. Cartilaginous fish and bony fish both have jaws, paired appendages, and whole vertebrae, and jawless fish lack jaws, paired appendages, and often are without whole vertebrae. Cartilaginous fish can have scales or be naked, jawless fish are naked, and bony fish have scales. Bony fish have swim bladders, and cartilaginous fish do not. Jawless fish, cartilaginous fish, and bony fish all have fins, gills, and dorsal nerve cords that lead to a distinct brain. They all also have postanal tails and notochords.
Yes, sail fish has a back bone. They are part of the phylum chordata, so they do have a back bone.
Yes, fish have a spine composed of vertebrae, like all vertebrates.
To protect the spinal cord. This is the function of vertebrae in all vertebrate animals: fish, lizards, lions, bats, etc., not just dogs. It also give structural support for the posture of land-based animals.
No
fish are are vertebrates
Cause it has a vertebrae (It has bones.)

A vertebrae are bones in the spinal column (also called spine or backbone)The function of the spinal column is to protect the soft spinal cord and to support the body and hold the head upright.Plural for vertebra. Bony segments forming the human spinal column.31-33 total vertebrae (most adults have 33 total vertebrae)Cervical vertebrae (C1-C7): 7Thoracic vertebrae (T1-T12): 12Lumbar vertebrae (L1-L5): 5Sacral vertebrae (S1-S5): 5Coccygeal vertebrae: 3-5IT IS THE SMALL BONES THAT FORM THE SPINAL CORDvertebrae i a series of bones to make up the spine. A vertabrae is an animal with a back bone. There are five classes of vertabrae: amphibeans, birds, fish, mamals, and reptiles.

a sword fish is a vertebrae
All fish have backbones. They are vertibrates. There are jawless, cartilaginous, and bony fish, but all have a vertebrae.
There are Five different types of Vertebrae in the Vertabral collumn (spine).1) Cervical Vertebrae (7)2) Thoracic Vertebrae (12)3) Lumbar Vertebrae (5)4) Sacral Vertebrae (5)5) Coccygeal Vertebrae (3)
Jawless fish are included in subphylum Vertebrata, but most jawless fish do not have whole vertebrae. Hagfish, for instance, do not have vertebrae at all, and lampreys have only reduced vertebrae. So, no, most jawless fish are not vertebrates.
Its primary purpose is to act as a shock absorber between adjacent vertebrae. Spinal discs also act as ligaments that hold the vertebrae of the spine together
