Sharks do lack real bones except for in there jaw. Without jaw bones sharks would not be able to survive because they would not be able to eat.
Yes they do it goes from the mouth to the gills theys how their gills open acually. So yea.
sharks only have one jaw, but many teeth
Sharks are cartilaginous fish.
The jaw of a shark is made of cartilage.
No

By the skin of one's teeth comes from a misquotation from the book of Job. He has lost everything, his friends and family have turned against him. "my bone cleaves to my skin and flesh and I am escaped with the skin of my teeth." A earlier translation says: " No bone hangs to my skin and the flesh and all I have is the skin around my teeth". This where is comes from but we now say that it means a 'close shave' or a win that wasn't a 'sure bet'.
While sharks and dolphins are certainly very different creatures, they do share some things in common. They both have dorsal fins, side fins and have a torpedo shaped figure. Additionally, they both live in water and are vertebrates.Despite the surface similarities, they are very different animals. Dolphins are warm blooded, while sharks are cold blooded. Sharks' skeletons are made out of cartilage, and dolphins' skeletons are made out of bone. Dolphins nurse their young, and sharks do not. Sharks have no hair whatsoever, while dolphins are born with hair around their noses. Additionally, sharks get oxygen through their gills underwater, while dolphins surface and get oxygen from the air through their blowholes.They both live in water (usually the ocean), they both don't sleep, they have sleek bodies for speed, dolphins, and usually sharks, both eat fish.Both have cartilagesDolphins and sharks are two ocean predators that have to compete for food and territory.They usually co-exist quite peacefully as part of a complex ocean eco-system, but occasionally they do attack and sometimes kill each other under various circumstances.Both are carnivorous (meat eaters)They both have many types, they both live in water, they both have fins, they both eat fish.
They are very strong and they can even bite through a bone and so it makes tearing the meat of its prey much easier.
Perhaps you mean a bone of contention.A bone of contention is something two people argue over - like two dogs arguing over a bone.
Teeth are teeth, neither cartilage or bone. But more similar to bone than cartilage.
The jaw bone is located in the head region directly below the teeth. It is attached to the side of your head. It is the only human skull bone that moves.
It is the bone that is attached to the bottom of your skull, where your bottom teeth are.
muscle attaches to bone by a tendon. muscle is attached to an immovable bone, this is called orgin, and the other end of the muscle is attached to a movable bone. this is called insertion.
Sternum/breast-bone, either directly or not
Teeth sit in the gums and their roots are anchored directly into the bone of the jaw. Lower teeth are called mandibular teeth because they are anchored in the mandible.

Both the origin and insertion points attach muscles to bone. The muscles are moving the bones so they must be attached directly to bone.
Dental implants generally fall into one of two basic categories. Endosteal implants are attached directly to bone to provide an anchor for artificial teeth within jawbone structures. A Subperiosteal implant is a metal framework that fits over the jawbone to help provide anchors for artificial teeth in the event that bone support structures are damaged or inadequate.
muscels are connected to bones by tough, and cord - lik tissue called tendons
teeth are not bone
I believe you are talking about the hyoid bone. It's the only bone in the body not directly connected to another bone. It is instead attached to ligaments and muscles.
