Nurse Shark
If you are familiar with Bilbo Baggins from the Lord of the Rings, the scientific name of the nurse shark is something like this: Ginglymostoma cirratum.
The one Bilbo said to summon elves to come to his rescue. The scientific name is a combination of Greek and Latin that means, “Curled, hinged mouth”. This is a description of the shark’s puckered appearance.
These typically slow moving creatures are harmful to humans. At some point, they would grow to a large size up to 14 feet. They have strong jaws filled with very sharp teeth. If you are a diver, it would be wise to not harm these sharks because you might have the chance of being bitten.
