Why protect great white sharks?
Simple they've been around longer than humans, they have more of the wright to live on earth than we do. Also all the stigma about sharks is untrue they don't go after humans just for the fact that they want to kill, they attack humans because they've mistaken you for a seal or something else they might eat in (THE SHARKS natural habitat) not humans! If you look at actual facts you will soon realise more people die in there own homes just by using a toaster than people who have just been attacked by a shark. Also I would like to make a point that sharks don't like the taste of human blood as there is a lot of iron in our blood compared to there natural food witch is why you mainly see people who have been attacked either with bite marks or parts of a limb missing. People are very rarely killed by sharks. also the Great whit shark even though the biggest one apart from the whale shark is actually more laid back compared to a tiger shark, the point is they are a living creature an cannot be blamed for what they do as they are only doing what nature intended them to do.

Why is the shark not a mammal?
Alright, so because a Shark is an animal it's Kingdom- Anamalia. Because it has a basic skeletal structure (Cartalidge, not bone) it goes into phylum chordata. Although, instead of being placed into the class mammalia like an elephant would, it is placed into the class chondricthyes, which is one of three classes of fish (The other two being Ostychthyes [Bony Fish] and Agnatha [Jawless fish]) that contains sharks and rays. It belongs here instead of mammalia because it's a fish, it lays eggs, has no fur, does not produce milk, etc. Look up what makes a mammal and you can compare them.
