Wobbegong

Both wobbegongs and grey nurse sharks have needle-like teeth which curve backwards.

Grey Nurse Shark

The teeth of the grey nurse sharks have little points on the sides (lateral cusplets).

Great White?

These teeth are quite different from those of the wobbegong and grey nurse sharks, they are triangular with serrations on the cutting edges, which are well worn.
