The Ocean Sunfish, also known as the Mola mola, looks like a huge fish head, with a wedge of a tail. You can find them in tropical oceans around the world.
So what was this 7-footer doing on a beach in Washington State? It washed up at Cape Disappointment State Park and was found dead at low-tide by a group of kids after a campfire program.
June Mohler, who works at the park, estimates its weight at close to 300 pounds. The cause of death is unclear -- a few days later it washed back into the ocean.

A critically endangered small tooth sawfish roams its new home at Oceanworld in Sydney on August 18, 2011. Measuring over 1.5 metres in length, sawfish have adapted to live in both salt and fresh water, while their long saw-like rostrum (nose) has evolved to expertly forage for food under the sandy ocean floor.

BROMLEY, UNITED KINGDOM - NOVEMBER 9: *** EXCLUSIVE *** Coral in Clayton Smith's fish tank on November 9, 2010 in Bromley, London, England. The flower beds maybe bare and winter is just around the corner but one Londoner is cultivating an underwater garden of the tropical kind. 'Reef Farmer' Clayton Smith, owner and founder of Reefworks, has turned his home-made coral tank into a treasure trove by creating a spectacular international coral farming business. Stretching 30 ft in length these 14 giant tanks contain over 150 species of exotic multicoloured coral from all over the world. Nicknamed 'The Bromley Reef' the colossal farm houses 2000 living colonies that are grown and then sold to enthusiasts in the UK and around the world. Now he is taking his quest for rare coral to another level by farming one of the richest but most delicate ecosystems in the world - the coral reefs of Indonesia. The marine biologist is so concerned with the impact of the unethical trade in endangered species. Coral reefs are found throughout the oceans of the world from the polar regions to the tropics. Although they cover only 0.2 percent of the ocean floor they provide a habitat for 25 percent of the ocean's wildlife. Scientists fear that unless drastic action is taken to conserve coral, up to 70 percent of reefs could be destroyed within the next 20 to 40 years.

SOUTH AFRICA - UNSPECIFIED DATE: ***EXCLUSIVE*** Sharks follow the Sardines. It is billed as the greatest natural show on earth and from these stunning images it is easy to why. Encompassing diving gannets, sharks, dolphins and brydes whales this is the increasingly rare and unpredictable sardine run. Underwater photographer Jason Heller travelled to the wild coast of South Africa this July to capture one of the unique predatory shows. Amazingly for Jason, who has been involved in underwater photography since 2001, this was his first experience of the sardine run. Followed by thousands of hungry dolphins, sharks, sea birds and seals, the sardines protect themselves from this onslaught by forming into giant balls called 'bait balls' which can measure as large as 65 feet, or 20 metres, in diameter. Using micro light planes to try and spot and relay the co-ordinates of the masses of fish and dive bombing gannets.

SYDNEY, AUSTRALIA: An extremely rare fluorescent yellow Port Jackson shark is shown to the public for the first time at the Sydney Aquarium, 30 March 2004. The two-year-old male named 'Mango', who has spent the last few months in quarantine at the Aquarium after being discovered caught up in a fishing net, derives its unusual bright yellow colouring from a rare form of albinism, a problem for the sharks as they normally lie on the seabed trying to camouflage themselves from predators.
