Just the other day, a marine mammal was caught in a human fish trap.
This poor orca was crying out for help.
Luckily, diver Rhys Cochrane, heard some odd sounds so he went to investigate the situation.
An orca was tangled up and had cuts across its face.
Rhys dove down, cut the net, and set the orca free.
Rhys was able to capture all of this on tape.
Way to go Rhys! You are a true hero .
