Anyone knows what these are ?
There were 2 of them accompanying mantas around a cleaning station and kept coming close to check me out. They are shark-like, with distinct dorsal fins, very fast swimming, huge eyes and look fierce. I kept turning around to fend them off with my fins and camera flash.
The instructor on the dive said they are commonly seen in RA following mantas and harmless. She had a laugh seeing me trying to fend them off underwater.
