The Airplane Graveyard - During World War Two, a fierce battle between American and Japanese forces on Kwajalein atoll left a trail of debris on the deep lagoon floor. This lagoon now has one of the largest collections of well-preserved aircraft in the world. As part of the first ever film crew allowed onto this secret military base, Jonathan explores a B-25, F4-U Corsair and Dauntless dive bomber still sitting on the bottom of the ocean, as if ready to take off. Killer Clams - Giant clams are no myth. In New England, people love clam chowder, but in the Pacific, some of the clams are as big as a suitcase! On a trip to Micronesia, Jonathan goes in search of Giant Clams. These clams are so big that people used to think they caught people...and it almost looks like they could. It turns out that the problem is too many people eating the clams. The Shark and the Lamprey - In 1998, Jonathan made a remarkable discovery about Basking sharks, the second largest fish on Earth. While diving with Basking sharks in the frigid waters of the Bay of Fundy, Jonathan saw parasitic lampreys on the backs of the sharks. This had never before been documented, so he returned the next year with a shark biologist and a lamprey biologist to attempt to recover living lampreys from the backs of Basking sharks. They didn't think Jonathan could do it. Wait until you see what happens.
