Narrator: A YEAR AGO, THESE TWO GREAT WHITES

SWAM IN PERFECT SYNC.

THIS IS INCREDIBLE!

IF THEY'RE STILL HANGING TOGETHER,

SCIENTISTS WILL HAVE TO REWRITE THE BOOK

ON GREAT WHITE SHARK BEHAVIOR.

IF THESE TWO SIBLINGS ARE STAYING TOGETHER,

TO MY KNOWLEDGE, THAT'S NEVER BEEN DOCUMENTED BEFORE

FOR WHITE SHARKS.

Narrator: NOW, 70 FEET DOWN,

AT WESTERN AUSTRALIA'S ISLE OF JAWS,

ANDY CASAGRANDE THINKS HE'S FOUND ONE OF THE SAME SHARKS.

Casagrande: BUT ONLY ONE. WHERE'S THE OTHER BROTHER?
