The ocean predators ranged in size, with some smaller ones and “some big mamas”, he said.
Bronze whalers can reach 3m in length and average around 1.5m-2.5m.
Bruce said he would be keen to get in the water and film the sharks in the future to show their docile nature and that they are not a threat.
“We have a group of ocean swimmers, and they go in like four times a week.
“They’ve named the resident one [shark] Felicity, and they see it most times. But yeah, it’s all just part of nature, which we are too.”
The spectacular school of fish, which Bruce also caught on film, was swimming in a circular motion to protect themselves from the sharks, he said.
“I tell a few friends that I call it the fingerprint of life, it’s pretty special.”
