The Shwarkeneger is a type of fish found off the coast of Japan. Males tend to be 3.7 meters (12 ft) to 6.0 meters (20 ft), whereas the females range from 3 meters (10ft) to 4.6 meters (15 ft). The earliest spotting was May 3, 2011 by Whale Wars on Animal Planet. While filming in the Western Pacific Ocean, the film crew spotted the creature attacking a school of whales 20 miles east of Japan.

Scientists Debra Keen and Greg Larker from Oxford University have been studying the strange animal since its’ encounter with humans. The Shwarkeneger has been noted of traveling in packs; as put in a journal, “They like to spot one another” (Keen & Larker, 2011). They have been referred to as the “King of the Ocean” (Keen & Larker, 2011). Their main diet ranges from algae to whales; however, the Shwarkeneger has been seen fighting to the death over mussels. No other species has threatened the Shwarkeneger’s existence and marine biologists are stating that the ecosystem is at risk because of the mutated creatures.

Dr. Christo Colombuster who specialized at UC Berkley in marine biology has done his thesis work on the Shwarkeneger and found that they will have dire effects on the ecosystem, "If we allow the Shwarkeneger to roam free, it will kill off all sea life; it has no competition other than itself, they will kill off one species at a time" (Colombuster, 2011). After a series of tests Colombuster found that the nuclear waste from the nuclear meltdowns in Japan can be blamed for the creation of the Shwarkeneger. The genetic makeup of the Shwarkeneger has traces of shark and that of the body builder who went missing. 80% of the genes have been mutated into a new DNA with 45 chromosomes. Other lab findings have concluded that they can only survive in salt water and reproduce at an exponential rate (Colombuster, 2011).
