Marine Biologist and lecturer Dr Koebraa Peters traces her deep connection to the sea back to her formative years.

Koebraa’s childhood was immersed in nature. She has strong memories of outings with her subsistence-fisherman father to the shoreline of Cape Town. Her childhood connection to the natural world laid the foundation for a life devoted to understanding and safeguarding marine ecosystems.

Initially drawn to a career in marine education and community outreach, Dr Peters’ academic journey took an unexpected turn during her Honours studies. Immersed in the study of terrestrial invasive species, particularly domestic cats, she wanted to learn more about marine invasion biology, which ultimately led her to pursue a PhD in Invasion Biology and altered the course of her professional pursuits. As her academic career progressed, Dr Peters began to uncover the hidden tapestry of life thriving within artificial structures, a revelation that would become central to her research. Her doctoral research focused on harbors, marinas, and recreational vessels and eventually led her to other man-made structures such as tidal pools.

Tidal pools, both natural and artificial, serve as sanctuaries for life within marine ecosystems. Natural tidal pools, sculpted by the relentless rhythm of the sea against rocky shores, offer sanctuary to a myriad of species. Varying in size and shape, these pools mirror the organic contours of the coastline and natural habitats, creating a mosaic of habitats teeming with life. Conversely, they are often engineered without adherence to the coastline’s natural form. Despite their artificial origins, these pools can play a crucial role in marine conservation, acting as sanctuaries for various species. Dr Peters’ research is slowly unveiling the historical significance of these pools, originally designed as fishing nurseries and safe havens for human swimmers, mitigating the risks of strong currents and human-wildlife conflicts. A notable distinction between natural and man-made tidal pools is their biodiversity. While both harbor diverse marine communities, man-made pools are less susceptible to invasive species, enhancing their role as sanctuaries for marine life. Dr Peters’ ongoing research highlights the need for further exploration into tidal pool biodiversity, with a focus on environmental factors and human interaction.

The allure of tidal pools lies not only in their ecological importance but also in their educational and recreational value. These pools provide unparalleled opportunities for hands-on learning, enabling students and researchers to observe marine life up close. The public, too, benefits from these accessible windows into the marine world, fostering a deeper appreciation for the ocean’s wonders.

Looking ahead, Dr Peters advocates for the conservation of tidal pools through sustainable practices and enhanced research efforts. Strategies to minimize human impact, such as responsible waste disposal and eco-friendly cleaning practices, are crucial in preserving these man-made ecosystems. Tidal pools, with their rich biodiversity and educational potential, stand as invaluable assets along our coastlines, deserving of further understanding and protection.
