Auszug:
At about 09:00 on 22 November 2019, a team of divers observed and filmed a single coelacanth (ACEP no. 34) at a depth of 69 m off the village of Umzumbe (between Hibberdene and Pumula) on the South Coast of KwaZulu-Natal. This site is about 325 km south of the iSimangaliso Wetland Park. The divers, Mike Fraser and Alan Fraser from Pumula and Bruce Henderson and Pieter Carstens from Somerset West, launched from the Injambili launch site at Pumula, with Benjamin Henderson and Marc Dukes acting as surface support in the boat. Henderson and Carstens used open circuit trimix and Mike and Alan Fraser used rebreathers with trimix diluent.

The reef on which the dive took place (the longitude and latitude coordinates for the discovery site are known but are being kept confidential in order to safeguard the coelacanth) is about 1 km from the continental shelf edge and is washed by strong currents. The coelacanth was first found by Alan Fraser who was swimming ahead of the other divers. On the video recorded during the dive (supplementary material) he can be heard shouting for Bruce Henderson, who had the GoPro 7 video camera with a 150 m underwater housing. The maximum depth of the dive was 72 m and the total bottom time 15 min, of which about half was spent with the coelacanth. Bruce Henderson filmed the coelacanth at a depth of 69 m.
