Question: The Hawaiian blackhead triplefin can be found in a coral reef in which 2.4 square mile area?
Context: Enneapterygius atrogulare is a species of triplefin blenny in the genus "Enneapterygius".  Although it is known as the blackthroat triplefin in the United Kingdom, it is also known as the ring-scale triplefin, black triplefin, eastern white-barred threefin, ringed triplefin, eastern Australian blackhead triplefin or the saddled triplefin in Australia.  It is a subtropical, non-migratory blenny found in coral reefs in the western Pacific Ocean, around Australia and Tonga.  Blackthroat triplefins swim at a depth range of 0-5 metres, and both juveniles and adults feed primarily on benthic algae, weeds, and invertebrates.  Male "E. atrogulare" can reach a maximum length of 5 centimetres. Snapper Ledge is a small coral reef located within the Florida Keys National Marine Sanctuary.  It lies to the southeast of Key Largo, to the south the Key Largo Existing Management Area and John Pennekamp Coral Reef State Park.  Unlike many reefs within the Sanctuary, this reef is not within a Sanctuary Preservation Area (SPA).  It is near Pickles Reef.  Since 2009, the Coral Restoration Foundation has used Snapper Ledge as a nursery site to grow Elkhorn Coral. The Census of Coral Reefs (CReefs) is a field project of the Census of Marine Life that surveys the biodiversity of coral reef ecosystems internationally.  The project works to study what species live in coral reef ecosystems, to develop standardized protocols for studying coral reef ecosystems, and to increase access to and exchange of information about coral reefs scattered throughout the globe. Midway Atoll ( ; also called Midway Island and Midway Islands; Hawaiian: "Pihemanu Kauihelani") is a 2.4 sqmi atoll in the North Pacific Ocean at .  As its name suggests, Midway is roughly equidistant between North America and Asia.  Midway Atoll is an unorganized, unincorporated territory of the United States.  Midway continues to be the only island in the Hawaiian archipelago that is not part of the state of Hawaii.  Unlike the other Hawaiian islands, Midway observes Samoa Time (, i.e., eleven hours behind Coordinated Universal Time), which is one hour behind the time in the state of Hawaii.  For statistical purposes, Midway is grouped as one of the United States Minor Outlying Islands.  The Midway Atoll National Wildlife Refuge, encompassing 590991.50 acre of land and water (mostly water) in the surrounding area, is administered by the United States Fish and Wildlife Service (FWS).  The refuge and most of its surrounding area are part of the larger Papahānaumokuākea Marine National Monument. Maro Reef (Hawaiian: Nalukākala - "surf that arrives in combers") is a largely submerged coral atoll located in the Northwestern Hawaiian Islands.  It was discovered in 1820 by Captain Joseph Allen of the ship "Maro", after whose ship the reef was named.  With a total area of 747 sqmi , it is the largest coral reef in the Northwestern Hawaiian Islands.  It contains 37 species of stony coral.  Unlike most atolls, the coral extends out from the center like spokes on a wheel.  Located about 850 mi northwest of Honolulu, Hawaii, Maro Reef contains about 1 acre of dry land which itself can be submerged depending on the tides.  Some scientists believe that it "may be on the verge of drowning" because the reefs are detached and are vulnerable to strong storm waves. The Røst Reef (Norwegian: "Røstrevet" ) is a deep-water coral reef off the coast of Lofoten, Norway.  The reef was discovered in 2002.  It extends over a length of about 35 km , and has a width of up to 3 km .  The reef is generated by the coral "Lophelia pertusa", and is the world's largest known "Lophelia" reef.  It is also the world's largest known deep-water coral reef.  The authorities have introduced regulations to protect the reef against trawling. The Hawaiian blackhead triplefin (Enneapterygius atriceps), also known as the Hawaiian triplefin in Hawaii, is a species of triplefin blenny in the genus "Enneapterygius".  It is a tropical blenny found in coral reefs in the Pacific Ocean, from the Hawaiian Islands, French Frigate Shoals, Laysan Island, and Midway Atoll.  Blennies in this species swim at a depth range of 1-23 metres, and inhabit dead coral and rock. The Florida Reef (also known as the Great Florida Reef, Florida reefs, Florida Reef Tract and Florida Keys Reef Tract) is the only living coral barrier reef in the continental United States.  It is the third largest coral barrier reef system in the world (after the Great Barrier Reef and Belize Barrier Reef).  It lies a few miles seaward of the Florida Keys, is about 4 miles (6 to 7 km) wide and extends (along the 20 meter depth contour) 270 km from Fowey Rocks just east of Soldier Key to just south of the Marquesas Keys.  The barrier reef tract forms a great arc, concentric with the Florida Keys, with the northern end, in Biscayne National Park, oriented north-south and the western end, south of the Marquesas Keys, oriented east-west.  The rest of the reef outside Biscayne National Park lies within John Pennekamp Coral Reef State Park and the Florida Keys National Marine Sanctuary.  Isolated coral patch reefs occur northward from Biscayne National Park as far as Stuart, in Martin County.  Coral reefs are also found in Dry Tortugas National Park west of the Marquesas Keys.  There are more than 6,000 individual reefs in the system.  The reefs are 5,000 to 7,000 years old, having developed since sea levels rose following the Wisconsinan glaciation. Norfolkia thomasi, known commonly as the Thomas' triplefin, is a species of triplefin blenny in the genus "Norfolkia".  It was described by Whitley in 1964.  The hemispherical eggs of the Thomas' triplefin are covered in sticky threads that help anchor them in the algae on their nesting sites.  This adaption helps insure the safety of the eggs.  One the eggs hatch the larvae that emerge are planktonic and they stick to shallow waters near the shore.  The matured Thomas' triplefin then ventures out into the coral reef and intertidal pools. The Coral Reef Restaurant is a themed seafood restaurant in The Seas with Nemo & Friends, which is located in Epcot's Future World.  One entire wall of the restaurant consists of a glass window that is eight inches thick and that provides a view into an aquarium.  While they eat, restaurant guests are able to watch tarpons, sharks, sea turtles, stingrays, groupers, and sometimes scuba divers in the six-million-gallon aquarium.  Artist Kim Minichiello painted the underwater scene that appears on the restaurant's menu covers.  Ron Douglas's cookbook "America's Most Wanted Recipes: Just Desserts" includes two dishes from the Coral Reef Restaurant: the Baileys and Jack Daniel's Mousse and the Chocolate Wave Cake.  One reviewer from "The Guardian" compares the Coral Reef Restaurant to the Sci-Fi Dine-In Theater Restaurant in Disney's Hollywood Studios, writing that both restaurants "are great settings" where "eating is awful."  In "The Unofficial Guide to Walt Disney World with Kids 2015", Bob Sehlinger, Liliane Opsomer, and Len Testa call the Coral Reef Restaurant one of the two most overpriced restaurants in Epcot, the other being Monsieur Paul.  In "Pauline Frommer's Walt Disney World and Orlando", Jason Cochran writes of his experience of the Coral Reef Restaurant, saying, "I had some of the worst food in my life... although the setting rocks."  In "Beyond the Attractions: A Guide to Walt Disney World with Preschoolers", Lisa Battista calls the aquarium view "incredible".
