Another night dive we did on our recent trip to the Maldives was at a feeding station for Nurse Sharks.
The sharks appeared as we were descending and before long there were around 10-15 around us - a couple up to 3 metres long. There was a strong current which meant we had to hang on to the rocks at the side of the sandy strip the sharks used for feeding but we were still only around 2 metres from them. And with the sharks being very comfortable swimming around the divers there were a few occasions where the sharks actually brushed the divers as they headed towards their food.
A couple of very large sting rays also put in an appearance to add to how special the dive was.
