![]() So they're - it was so close that it had to rotate around to kind of eyeball me up and down. One peeled off, but the other one moved right in towards me and came so close that actually, it couldn't even see me from looking dead on because like all fish, they kind of have the eyes on their - side of their head. And I had never seen one before so - you know, I was a bit younger and more excited and I guess green.Īnd I put on my snorkel gear and grabbed my camera, ran to the back of the boat and pretty much just cannonballed into the water and saw these huge two tiger sharks approaching me, 3-and-a-half-foot-wide heads coming close. I went into the shower to kind of wash up, and I heard someone yell tiger shark. We were actually looking for sharks, so we were baiting them in, trying to get close. And I was on a boat - a live-aboard, meaning you kind of live and sleep on the boat. I mean, it was a beautiful late afternoon, early evening in the Bahamas. I'd like to start with an experience - and this is something that you mentioned in a TED talk - of an encounter with a shark about 10 years ago. He spoke with FRESH AIR contributor Dave Davies.ĭAVE DAVIES, BYLINE: Well, Dr. His work is featured in two of the episodes of The Discovery Channel's recent Shark Week. Hammerschlag has some tips on how to stay safe around them, and he'll explain how we're much more of a threat to sharks than they are to us. The tags he implants in sharks transmit information about the health and behavior of these predatory animals. He's caught and tagged more than a thousand sharks for research and has studied and filmed some of the largest of the shark species, the great white and tiger sharks. He spends a lot of time on and in the water. Neil Hammerschlag is a marine ecologist at the University of Miami, where he directs its Shark Research and Conservation Program. GROSS: Our guest today is a real-life Hooper of sorts. All this machine does is swim and eat and make little sharks. ![]() RICHARD DREYFUSS: (As Matt Hooper) What we are dealing with here is a perfect engine, an eating machine. It's summertime, when a lot of us head to the beach and try not to think about the man-eating sharks we've seen in movies like "Jaws." Remember Hooper, the shark expert played by a young Richard Dreyfuss? These include killer whales, leopard seals, large sharks, sunflower sea stars, marlin, and other highly migratory species.This is FRESH AIR. ![]() ![]() Animals that have few or no predators of their own are called top predators. Ambush predators like mantis shrimp, some octopuses, some eels, and scorpionfish, capture their prey by hiding and suddenly attacking. Pursuit predators like sharks, box jellyfish, sunflower sea stars, and many fish like herring, cod, and tuna hunt for their prey. There are many kinds of predators that feed on many kinds of prey. Predators more actively feed on other animals. Filter feeding animals include animals like bivalves, tube worms, sponges, and even large animals like baleen whales and manta rays. Filter feeders strain their food (plankton and detritus) directly from the water. Larger animals, including some marine snails, fish, reptiles, and mammals, graze on algae. Some zooplankton including copepods, rotifers, and larval stages of some fish and invertebrates are grazers and drift through the water grazing on phytoplankton.
