These gentle giants come to quarter mile reef at Sodwana Bay around december each year to gestate before giving birth to their young at an unknown location. They normally stay at Sodwana for around 2 or 3 months. We were lucky on this day as the visability was almost perfect and there was no surge or current to speak of and all the sharks were as curious about us as we were abouth them, giving us some very nice pictures and film footage.
