Simon Berrow: How do you save a shark you know nothing about?

The video discusses basking sharks, highlighting their size, diet, and presence in Ireland. It covers their historical importance to coastal communities, particularly for oil extraction. The decline in their population due to overfishing is addressed, along with conservation efforts and research initiatives. Genetic studies reveal low diversity, suggesting a risk of extinction. Innovative sampling techniques, like collecting slime, are explored to gather genetic data. The video emphasizes the need for further research and conservation to protect these magnificent creatures.
