Oceans (1x15)

Date de diffusion: Avr 27, 2012

The Big Question: “Do sea monsters really exist?” Finding out how crucial the ocean is to our ecosystem, Harrison discovers that although monsters might get the attention, it’s the little things that count. For example, a tiny creature called phytoplankton creates half of the oxygen that we breathe. Using potatoes, a marine biologist helps Harrison figure out how fish drink! My Great Challenge: Harrison hosts a challenge for his guests to figure out how to make plasticine float… then, with musical accompaniment, he reveals the identity of “the monster in the sea”. In the Field: Harrison visits the shark tank of a sea aquarium to find out if it’s true that sharks die if they fall asleep.
