For question 14 (what does shark skin feel like), the answer isn’t just rough. If you run your hand one way on a shark’s skin, it is smooth, and the other way is rough. This is because their dermal denticles (the scales on a shark) all face the same way, which makes them swim faster. :)

They are. Vertebrates need to have characteristics such as a spinal cord and an internal skeleton, which sharks have. (Vertebrates can have cartilage skeletons of bone skeletons)
