The incredible moment a pod of killer orcas helped free a trapped humpback has been caught on video.
The remarkable nature encounter was captured off the Western Australian south coast near Bremer Bay on January 10.
It was a ‘rescue’ that stunned onlookers because orcas often feast on humpbacks in the ocean – injured or otherwise.
And with the whale seemingly tangled in ropes, it presented an easy meal for the feared ocean predators, who often also attack and kill great white sharks.
‘It would usually be part of their diet so when we saw the injured humpback and the approaching orca, we were concerned,’ Whale Watch Western Australia’s Gemma Sharp Sharp told the Mandurah Mail.

The trio of orcas, named Hookfin, Blade and Matriach Queen, were expected to devour the trapped whale – but amazingly they all appeared to lose interest once the humpback was set free.
‘Lifting his fluke we could see that this humpback whale was entangled and our hearts sank, (it is) a terrible situation to be in when trying to defend yourself against the ocean apex predators,’ a statement from Whale Watchers Western Australia read.
‘He rolled and during this process we could see Blade swimming directly underneath his fluke and looking at the rope entanglement… the orcas then charged towards the humpback while he defended himself with pectoral fins and fluke swiping.
‘Matriarch Queen arrived and moved towards the humpback whale which caused a commotion of white water and then something incredible happened – a large chunk of the green rope that was entangling the humpback floated free behind him.’
Having been freed in the nick of time, the humpback whale then swam away from the pod.
Witnessing a humpback whale swimming in Western Australian waters in January was also unusual.
Humpbacks usually feed in Antarctica at this time of year.
