Size relative to a 6-ft (2-m) man: Sand sharks, also known as
sand tigers and gray nurse sharks, have a deceivingly ferocious
look. They are large-bodied and display a mouthful of sharp
teeth that protrude in all directions, even when the mouth is
shut. Despite this, they are a docile, non-aggressive species,
known to attack humans only when bothered first. Sand sharks are
brownish-gray with rust-colored spots on top and white
underneath. They have a flattened, cone-shaped snout and a
distinctive, oblong tail with a notched, upper lobe that is
significantly longer than the lobe below. Individuals range in
size from 6.5 to 10.5 feet
