Narrator:
THE BLACKTIPS ARE HERE,
LEMON SHARKS, TOO.
BUT THEY QUICKLY GET OUT
OF THE WAY FOR A HUGE TIGER.
LOOK, IT'S EMMA.
SHE'S THE MATRIARCH.
WHEN I FIRST MET EMMA,
SHE WAS ROUGHLY 11 FEET LONG.
BUT NOW, SHE'S EASILY PUSHING
15 FEET.
Narrator:
THEN NEIL SPOTS SOMETHING
MORE SIGNIFICANT
THAN EMMA'S SIZE.
SHE HAS WOUNDS AND BITE MARKS
ON HER BODY.
THE BITE MARKS ARE WHAT
WE CALL MATING SCARS.
Narrator:
NO MATTER WHAT SPECIES,
SHARK MATING IS
A VIOLENT AFFAIR.
IN THIS RARE FOOTAGE,
TWO MALE WHITETIP SHARKS
LOCK A FEMALE IN THEIR JAWS
AS ONE OF THEM MATES WITH HER.

FEMALE TIGERS AT TIGER BEACH
OFTEN SHOWED
THE SAME VIOLENT WOUNDS.
WE'RE STARTING TO SEE A LOT
OF TIGERS LIKE THIS.
Narrator: THE MATING SCARS,
THE FULLY DEVELOPED EGGS
THEY FOUND,
AND ALL THE FEMALES
IN THE AREA --
THE EVIDENCE IS BUILDING UP.
THE FEMALE-TO-MALE RATIO
IS 9:1, AND SO,
WHY ARE WE SEEING
SO MANY FEMALES?
AND A LOT OF THOSE FEMALES
ARE VERY LARGE
AND EXHIBIT MATING SCARS.
SO, THAT LED US TO BELIEVE,
YOU KNOW,
"COULD IT BE LINKED TO SOMETHING
RELATED TO REPRODUCTION?"
