How Many Sharks Are In the Ocean?
They believe there are probably too many sharks to count, but estimate around 400 million species and over a billion sharks altogether. There are lots of different kinds, all but two kinds, the River Shark and the Bull Shark, stay in the ocean. These two species can also be found in fresh water. Sharks have been around as long as dinosaurs, some say longer, but around 450 million years. The largest kind of shark is a whale shark, about 60 feet long, and the smallest is a dwarf lantern shark, approximately 7 inches long. Sharks don't have skeletons. They have cartilage not bones, like people have in their ears and noses. Sharks are my favorite ocean creature but I'd rather read about them than swim with them. The new words I learned from reading this Wonderopolis report were Cartilage: the connective tissue that sharks are made of instead of bones. Mariners: Old time sailors. Recreational: Do something for fun.

My name is Emily. I have two dogs. One is a shitzu named Zoey she is a four year old female. And the other is a Cairn Terrior named Max he is a two year old male. I also have one male betta fish. We are also going to get some chickens soon. The last and final animal I have is my little brother named Nolan he is a eight year old male. When I grow up I would like to be a domestic veternarian not a farm one. The reason why I want to be a DOMESTIC veternarian is becuase I love dogs. So hopefully I won`t have to deal with the cats a lot. Not that I don`t like cats it`s just that I have never had one before so I don`t know how to care of them. Also, when I grow up I`m gonna have two dogs, I`m not sure what kind yet, and two to three kids. If I have three I want two girls and one boy. If I have two kids I want one boy and one girl. I love the sport soccer and I also do tae kwon do, and teach these cute 6 year old kids. That is ME and what i am going to do when I grow up!
