🐬 Plett Stranding Network responds to a Common Dolphin stranding
Yesterday, the Plett Stranding Network was activated to assist with the necropsy of a freshly stranded young adult female Common Dolphin (Delphinus delphis).
Led by experienced cetacean biologist and local, Dr Gwen Penry, the necropsy provided an important opportunity to learn more about this individual and the potential causes of her death. She had a very thin blubber layer, suggesting poor nutritional condition. An old, semi-circular healed wound was also noted, while foam in the trachea suggested she may have taken on some water during the stranding.
Perhaps most unexpectedly, a fetus was found inside her. Based on the size of her teeth, Gwen believes this may have been her first pregnancy. Pregnancy-related complications are one possible explanation for her death, but the exact cause cannot be confirmed.
Measurements, photographs, and biological samples were collected, including tissue from the lungs, liver, kidneys, muscle, and blubber, as well as stomach contents, skull, and rib samples. These will support further research, including genetic and toxicological analyses, helping us better understand the health and ecology of dolphins along our coastline. The samples have been sent to Bayworld in Gqeberha, where they will be curated by Dr Greg Hofmeyr and his team. All samples were collected under government-issued permits by qualified and trained personnel.
A big thank you to Dr Gwen Penry, Chanel Visser, Senior Marine Ranger at CapeNature, Lauren Moriarty and the NVT interns, Rahul and Priyanka from Eco Explorer, our Conserve Eden interns, Kade and the ORCA Foundation volunteers, and the volunteers of the Plett Stranding Network.
Every stranded animal provides an opportunity to learn. Through careful examination and collaboration, these animals can continue to contribute valuable knowledge to marine conservation — even after death.
