Ragged-tooth sharks are also called sand-tigers. Ragged tooth sharks spend a lot of time patrolling the shallow reefs around Durban and Aliwal shoal, close to the sandy bottom the sharks rub their bodies on the sandy bottom to dislodge parasites and perhaps this could explain their alternate name? The Blue Wilderness team will get you up close and personal with ragged tooth sharks on a dive to the world famous ‘Raggie cave’. Here you can wait in mid-water outside the cave, so as not disturb the ragged tooth sharks. Most times, on the dive, you will view up to 12 sharks patrolling back and forth along the length of this long gash of a cave, as it slices sideways into the reef.
