Since he was tagged last October, Ironbound has traveled over 2,700 miles.
Ironbound was first tagged last fall in the waters off West Ironbound Island, Nova Scotia.
"[The discovery] shows that some of the big steps in evolution we thought were restricted to land animals actually first took place in fishes," said researcher John Long.
The bacteria were found at Loki's Castle—a field of active marine hydrothermal vents.
"We have new species turning up that are already contaminated and so we have missed the window to understand these species in a natural environment," said marine ecologists Alan Jamieson.
Researchers discovered the coral gardens using a remotely operated vehicle known as SuBastian.
The whales were observed in the Northeast Canyons and Seamounts Marine National Monument, located around 130 miles east-southeast of Cape Cod, Massachusetts.
The animal measured more than 13 feet in length, according to marine researcher Darren Stevens.
Upside-down jellyfish are found in warm coastal waters—such as mangroves, bays and lagoons—around the world.
For centuries, ambergris has been highly prized for its unique for its use a perfume ingredient.
The female shark measures around 15 feet and 5 inches in length and weighs more than 2,000 pounds.

"These sharks are not the vicious man eaters that Hollywood movies make them seem," underwater videographer Szilard Janko said.
The venom of some box jellyfish species is considered to be among the most powerful in the world.
"Gear retention—when marine animals escape from fishing gear with parts of the gear stuck on their bodies—has been recognized as a potential problem for some time," researcher Carl Meyer said.
While jellyfish are fairly common in the area, such large congregations are quite unusual at this time of year.
The shark is named after the famed Italian explorer John Cabot.
The shark was tagged in September by researchers from non-profit OCEARCH near Nova Scotia in Canada,
The findings are some rare good news for corals around the world, which are facing numerous severe threats.
Some species of jellyfish are able to grow back tissue that has been lost.
"If she is dreaming, this is a dramatic moment. You could almost narrate the body changes and narrate the dream," the scientist said.
Plastic fragments are frequently ingested by a wide range of marine animals that often mistake the substance for food.
Sea turtles are among the oldest creatures on the planet. However, they are facing significant threats from human activities.
"The presence of corals in these extreme mangrove habitats challenges our understanding of the conditions some corals are capable of living in," researcher Emma Camp said.
Researchers say they were stunned by the close encounter.
The bluntnose sixgill is one of the largest sharks in the world and it has not changed much in around 180 million years.
"In the history of fisheries science, only two pocket sharks have ever been captured or reported," Henry Bart, director of the Tulane Biodiversity Research Institute, said in a statement.
The oldest embryo kills and consumes its siblings, causing it to grow exponentially bigger and stronger.
The animal was observed during an expedition aboard the National Oceanic and Atmospheric Administration's Okeanos research vessel.
The video was captured by a team of researchers from the non-profit Atlantic White Shark Conservancy.
