Secrets of Whale Shark Migration Revealed:
Published August 21, 2013
The world’s biggest fish are hungry migrators on a mission, according to a tracking study that mapped whale sharks’ long journeys around the Gulf of Mexico and Caribbean to a favorite feeding hot spot off the Yucatan Peninsula.
And one whale shark’s incredible 5,000-mile (7,200-kilometer) swim could even help solve the long-standing mystery of where whale sharks give birth—an event no scientist has ever seen.
[The data] could help answer a question that has plagued whale shark researchers for years: Where are all the females? Quintana Roo is more than 70 percent male, and other global aggregations show the same gender imbalance.
"You can’t have a stable population with that many males. You don’t see that in nature," Hueter said.
"The females have to be somewhere, and we hypothesize that mature, pregnant females undergo long migrations to the middle of the ocean, near seamounts or remote islands … and that’s where they give birth," Hueter explained. "In coastal zones where the feeding aggregations are, their young-which are less than two feet long at birth—might be subject to higher predation."
He added, “We feel good about the hypothesis, but it’s out there to be tested. So now we’ll have to see if it’s proven right in the years to come.”
David Attenborough - BBC Africa - Epilogue
I’ve just finished watching this incredible series. It is beautifully shot, and good ol’ Sir Dave rocks it like the nature King he is. I thought the series had the strongest conservation message I’ve heard in a series like this, with a whole episode dedicated to highlighting conservation projects on the ground, and steering the message away from single-species and towards ecosystem-level protection, making that link between us, our future, and everything that exists on this planet. They even included the usually-left-out marine side of things.
It’s nature propaganda at it’s most beautiful and elegant.
Like if you love Attenborough!
