  • (dramatic piano music)

  • - Today we're exploring the deep ocean

  • and its rarely seen creatures.

  • My grandfather Jacques Cousteau

  • was always looking to chronicle the wonders of the ocean,

  • and the giant isopod is one of the most fascinating

  • and strange-looking.

  • These crustaceans live thousands of feet

  • beneath the ocean's surface,

  • typically between 500 and 7,000 feet deep.

  • They can grow up to two feet long,

  • but this one's just a baby.

  • The reason they're so big

  • is due to something-- - [Man With Hat] Sorry.

  • - Is due to something called sea gigantism.

  • We don't know why this happens.

  • It might be due to deep ocean pressure,

  • or to scarcity of food resources.

  • Either way, these guys are huge.

  • They're carnivores and they have four sets of jaws,

  • but can go for years without eating.

  • Are you guys eating?

  • You barely lasted an hour.

  • One isopod in captivity in Japan

  • survived five years without eating.

  • OK, give me a chip.
