A New Brunswick man has made a career as TikTok’s resident zoologist after getting laid off from his job in environmental management.

Mamadou Ndiaye has over 16 million followers on the app. He combines his love for wildlife with his degrees in environmental science from Rutgers to make entertaining and educational videos about animals.

In one video with more than 20 million views, Ndiaye explains how long animals can hold their breaths underwater.
