Shark gets a little too close for comfort

[Pete L]

Had this interaction last weekend while filming some Grey Nurse Sharks. There was about 50 or so in a small area & I swam into this split in the rock & there were maybe 5 or 6 inside here.
Not sure why the aggression, maybe the lights?
Anyways, I got out of there pretty quick.
