Phantoms of Evolution - The Unknown Underwater Predators | Free Wildlife Documentary

With the aid of modern technology, we reveal the unknown behaviour of some unusual species of sharks: lemon sharks and their white-tip reef counterparts. Our film trip begins on the Bahamas. To be more precise: in the turquoise-blue waters of the Grand Bahama Bank, in an exactly fixed location. In spring, 70 - 80 pregnant lemon sharks arrive here. This huge shark population was first discovered just a few years ago by shark researcher, Professor Sam Gruber. Many of the females are tired and rest on the seabed. Pregnant tiger sharks swim in the midst of this group. Without any protection whatsoever, our cameramen shoot their footage, surrounded by sharks and succeed in capturing images hitherto unseen.
We continue our journey to Gainesville, Florida, to meet Gordon Hubbell, the leading shark denture expert with the world’s largest shark denture collection. He knows everything about the evolutionary history of the lemon sharks, in addition to those of the white-tip reef variety off Cocos Island, Costa Rica. Here, we encounter large schools of fish, unprecedented numbers of stingrays, as well as hammerhead sharks. However, it is the white-tip reek sharks that make the biggest impression. Their performance begins late at night. Marauding, they patrol in large groups through the reefs and hunt everything that moves. Scales and dead prey fish float above the reef - a welcoming change of diet for the ubiquitous barracudas.
