Exciting Lemon Shark Facts for Kids A lemon shark may have a very cute and funny name, but its very menacing appearance is far from it. Lemon sharks are very burly and powerful creatures that can grow up to 10 feet in length. These creatures are usually found on the Southeastern coast in the United States and also in the Gulf of Mexico. They usually migrate to far places during the summer and return to specific sites when breeding. They are so-named because of their slightly yellowish color.
