The Sandbar shark (Carcharhinus plumbeus) has a nice big first dorsal fin which might look scary if you see it in the water but they are harmless to humans. We are probably not as harmless to them because they are listed as vulnerable on the IUCN red list.
They are named so because apparently they like hanging out at sandbars. They proabably love a good sangria.
Some parents hate kinetic sand and I don't blame them but once you start building kinetic sand castles, you'll see why kids love them.
