Robberg Whale Stranding
Before we begin: If you see a stranded animal please report it to the Plett Marine Animal Stranding Network on 079 463 4837. Please save this number for the future.
The wildside of Robberg was recently the site of a heroic mission to rescue a stranded whale and, while the mission ultimately didn’t yield the desired result, those involved must be commended for their quick response, their dedication, collaboration and care for our marine animals – thank you. Below, CapeNature Marine Ranger, Chanel Visser shares the story in her own words.
“Strandings are rarely the result of one simple cause. Often, they involve a combination of issues. A sick or injured whale may lose strength or become disoriented, leading it into shallow water. Whales use echolocation and shallow sloping beaches like those along the southern Cape can confuse their sonar. In some species (not Humpbacks), whales strand together out of loyalty to one another, even if only one individual is in distress. Shifts in ocean temperature, prey movement, or even underwater noise pollution can cause whales to enter unfamiliar or dangerous areas.
The whale was alive but stranded again on the morning of Tuesday, 20 May, and with public access restricted to ensure safety, the Plett Stranding Network made the difficult decision to proceed with humane euthanasia. The operation was led by SAPS bomb squad expert Johan Ehlers, who has extensive experience in large mammal euthanasia.”
“While deeply distressing, this was the kindest option to prevent further suffering. Drug injections are not viable for whales due to their physiology. Explosives remain the most humane method.”

“The euthanasia was carried out successfully and the whale will contribute to scientific knowledge and conservation efforts. Blubber and muscle samples have been collected for further research, and additional data will be gathered to support long-term monitoring of whale health, disease, reproduction, and threats in the marine environment. The carcass will be towed out to deep sea for disposal when sea conditions permit.”
“This incident, while heart-breaking, showed the incredible collaboration and resilience of our network. We’ve learned valuable lessons and grown both professionally and personally.”
Chanel Visser, Senior Marine Field Ranger
CapeNature and the Plett Stranding Network extend a word of thanks to all who contributed to the effort, including reserve staff, volunteers, marine scientists, SAPS, and the NSRI.
The team from Plett Shark Spotters, who are involved in the Plett Marine Animal Stranding Network posted the following on their social media accounts shortly after the incident:
“On Monday afternoon, a juvenile humpback whale, approximately 7 meters in length, was stranded in the surf on the Wild Side of Robberg Nature Reserve. This is the time of year when humpback whales migrate north along South Africa’s coastline from Antarctica to breed and calve. NSRI, CapeNature, and the Plett Marine Animal Stranding Network responded immediately, working tirelessly through the afternoon with help from members of the public to try and re-float the whale.
Despite multiple attempts to guide it into deeper water, the whale continued to re-beach. By this morning (Tuesday), it was determined by authorities that euthanasia was the only option left to prevent further suffering. Samples have been collected by marine scientists for necropsy to better understand the cause of stranding. Thank you to everyone who responded so quickly and gave everything to try to save this animal.
