Grant success: KAKENHI Early-Career Scientist grant to Dr Wyatt

Dr Wyatt has been awarded an Early-Career Scientist (KAKENHI) grant by the Japan Society for the Promotion of Science (JSPS) to clarify several mysteries surrounding the critically threatened whale shark. The research aims to quantify the global prevalence of foraging specialisation, fasting and herbivory, and | Click for More →

Chemically unravelling mysteries surrounding the world’s largest fish

Foraging, starvation and herbivory in the globally threatened whale shark Whale sharks, filter feeding sharks that travel tropical oceans in search of their microscopic prey, are globally threatened. Despite being the world’s largest fish, reaching over 12 m in length and 21 tonnes, many facets | Click for More →
