Another one of five pilot whales released into the sea in False Bay on Sunday afternoon, has rebeached.
National Sea Rescue Institute spokesperson Craig Lambinon says it is the fourth whale that has rebeached.
A pod of 19 pilot whales, mostly adults, beached at Noordhoek Beach in Cape Town on Sunday morning.
A twentieth whale had managed to swim back into the surf.
Nine whales that were in poor health were euthanised on the beach.
Another five died naturally.
