Speed Kills: Ocean

The Weekend Australian - Review - - Television -

Satur­day, 7.30pm, Nat Geo Wild The fastest an­i­mals on the planet use speed to kill, so in this spec­tac­u­lar nat­u­ral his­tory se­ries, high-speed cam­eras and a de­tailed knowl­edge of anatomy com­bine to show us how they do it in mag­nif­i­cent and some­times chill­ing de­tail. In the com­ing weeks we’ll see the fastest crea­tures in the episodes Sa­van­nah and Jun­gle, but tonight’s de­but episode, Ocean, is all about things that go fast in the sea. Ocean crea­tures com­bine hy­dro­dy­namic de­sign with stealth and sub­terfuge. Did you know that fish have a swim blad­der? This in­flat­able air sac pro­vides buoy­ancy so the fish can use all its mus­cle power for propul­sion. And what about those sen­sors along the bod­ies of sharks, so sen­si­tive they can de­tect in­di­vid­ual fish in a school, or the teeth-like in­ter­lock­ing struc­tures on their skins that mean wa­ter just slides off. A trea­sure trove of all the fas­ci­nat­ing and mostly un­known skills and de­sign fea­tures that make sea crea­tures fear­some as well as mind­bog­glingly fast.
