Once thought to be extinct, and known only by fossils, the discovery of the Coelacanth is a remarkable story - as is the ensuing research findings about these unusual fish
On 21 May 2026, SmallTalX® welcomed Prof Mike Bruton to the Helderberg Nature Reserve Environmental Education Centre for a fascinating journey into one of the most remarkable scientific discoveries of the twentieth century: the coelacanth.
Prof Bruton's talk traced the extraordinary story of a fish once believed to have gone extinct millions of years ago and known only from the fossil record. Audiences were introduced not only to the dramatic circumstances surrounding its rediscovery, but also to the unique biology of this ancient species. From its lifespan of up to a century and gestation period of around five years to its deep-water habitat and unusual anatomy, the coelacanth remains one of the most intriguing fish on Earth.
The story is also a uniquely South African one. It began on 22 December 1938, when museum curator Marjorie Courtenay-Latimer noticed an unusual fish among the catch brought into East London harbour. With the assistance of ichthyologist Dr J.L.B. Smith, the specimen was identified as a coelacanth, sparking decades of research, exploration, and discovery. Prof Bruton, himself part of the journey, wove together the scientific, historical, and human dimensions of this story, highlighting the many individuals whose curiosity and dedication helped unlock the secrets of this elusive species.
The talk also showcased the evolution of scientific methods used to study coelacanths, from early expeditions and underwater observations to modern technologies that have transformed our understanding of their behaviour, ecology, and conservation needs. As one of South Africa's leading ichthyologists and a key figure in coelacanth research, Prof Bruton offered unique insights into both the challenges and rewards of studying a species that remains rare, mysterious, and vulnerable.
Adding further depth to the evening was Prof Bruton's interdisciplinary approach to science communication, reflected in his display of artefacts, artwork, and publications that brought the coelacanth story vividly to life. SmallTalX® was honoured to host Prof Bruton and to share his wealth of knowledge with our audience.
We now look forward to welcoming Prof Karin Jacobs, who will take us into the hidden world beneath our feet to explore soil ecology, biodiversity, and their vital role in supporting a healthy and sustainable future.
