On December 13th, BioGrad arranged for Dr Robert Wynne to engage in an enlightening session with the Year Five classes at Our Lady of Lourdes Catholic Primary School, delving into the exciting world of shark biology and conservation. Driven by his lifelong passion for sharks and marine life, Dr Wynne aimed to captivate the students, nurturing an interest that could potentially inspire future zoologists and marine biologists.
Throughout the enjoyable afternoon, Dr Wynne assessed the students’ existing knowledge about sharks, intending to dispel any misconceptions that might portray these creatures as objects of fear. While many students were very familiar with great white sharks, tiger sharks, hammerhead sharks, and even the extinct megalodon, Dr Wynne aimed to unravel the mysteries of lesser-known shark species, such as the uniquely parasitic cookie-cutter shark and the visually intriguing, tasselled wobbegong shark. He elucidated the evolutionary marvels that have shaped these creatures into efficient hunters over millions of years.
One key objective of the talk was to introduce the concept of evolution, demonstrating how organisms adapt to exploit ecological niches. Instead of explaining the often-complex nature of natural selection to a young audience, Dr Wynne prompted the students to examine the shape of different shark species’ teeth and relate it to each shark’s specific diet. Providing a selection of shark teeth, he engaged the class in a discussion on how they use cutlery to eat different foods, drawing parallels to the variety of shark teeth in nature. Dr Wynne outlined the differences between the broad serrated teeth of great white sharks and tiger sharks, adapted for consuming large marine mammals, and the needle-like teeth of white-tip reef sharks, designed to puncture and hold slippery reef fish.

Dr Wynne also shared insights into his own research, focusing on the population genetics of captive and wild sand tiger shark populations. Breaking down the complexity of the research into understandable terms, he conveyed a clear take-home message, stressing our responsibility to care for the environment and its inhabitants. Many shark species play a crucial role in regulating seas and oceans, and overexploitation from commercial fishing could lead to dramatic ecological and economic consequences.
The occasion also served as a platform to explore the diverse wildlife in the United Kingdom, emphasizing that the UK coastline hosts over 40 species of sharks and rays annually. Notably, Britain is home to the basking shark, the world’s second-largest fish, as well as the fastest-swimming species of shark, the shortfin mako shark.
Seizing the opportunity, Dr Wynne informed students about their potential involvement in shark conservation and research initiatives, particularly through the Shark Trust’s “Great Egg Case Hunt.”
This annual endeavour encourages families and young individuals to participate in beach cleans and search for mermaid’s purses, contributing valuable data to understanding UK shark populations. The Shark Trust, a UK charity with a global impact, tirelessly works to enhance the conservation status of sharks, skates, and rays.
In addition to fostering scientific curiosity, Dr Wynne underlined the importance of dedication and passion when pursuing a career in science or any other field. He encouraged all students to follow their curiosities and interests, ensuring that they let their passions drive them throughout their school careers.
