Seal (Floreana Island, EC)

By alexstokes25

(2022-09-11)

Floreana Island has, arguably, the most interesting human history of all of the Galapagos Islands. It is the site of the first “post office”, established in 1793 by whalers, and it was the home to the first Galapagos resident — a bold Irishman named Patrick Watkins who lived there from 1807-1809.

Floreana was the first island to be colonized by Ecuadorians in 1832. It was a penal colony that didn’t last long because of the lack of fresh water. A fish canning plant was established there by Norwegian immigrants in 1924; it lasted only a couple of years. A few years later, Friedrich Ritter, a German doctor, arrived with his female companion Dore Strauch, who suffered from multiple sclerosis. A doctor of holistic medicine, Ritter removed all of his teeth and took with him stainless-steel dentures to avoid any dental complications. Together, they set up a very successful garden and lived off the land.

A pregnant Margret Wittmer arrived in 1932, with her husband Heinz and her step-son Harry. They built a house and also established an agricultural lifestyle before giving birth to their son Rolf, the first person to be born in Galapagos.

Floreana is most well-known for being the site of several mysterious disappearances in the 1930s—the one receiving the most attention being that of a supposed Austrian baroness, who had arrived shortly after the Wittmers with her three servants.

Shark (Palmyra Atoll)

By alexstokes25

(2022-09-11)

Palmyra Atoll, also referred to as Palmyra Island, is one of the Northern Line Islands (southeast of Kingman Reef and north of Kiribati). It is located almost due south of the Hawaiian Islands, roughly one-third of the way between Hawaii and American Samoa. North America is about 3,300 miles (5,300 kilometers) northeast and New Zealand the same distance southwest, placing the atoll at the approximate center of the Pacific Ocean. The land area is 4.6 sq mi (12 km²), with about 9 miles (14 km) of sea-facing coastline and reef. There is one boat anchorage known as West Lagoon, accessible from the sea by a narrow artificial channel.

Controversial Yonaguni Monument of Japan

By alexstokes25

(2022-09-05)

Submerged rock formations at Yonaguni have mystified scholars for many years. Some believe the formations are natural phenomena and others argue there is evidence that they are man-made, the remains of a fabled Pacific civilization which vanished into the ocean.

The rectangular monument, which was first detected by a scuba diver, is more than 165 feet (50 metres) long and some 65 feet (20 metres) wide. A number of scholars have visited the site, but its origin remains uncertain. According to some, the monument is a man-made stepped pyramid. In addition to many straight lines, some of the rocks purportedly have carvings. Nearby are other formations, suggesting a submerged ancient city. This theory contends that the structures are at least 5,000 years old and belong to a lost civilization—possibly the legendary Mu or Lemuria.

Other researchers, however, claim that the monument is natural, shaped over the years by underwater currents. They state that the symmetry of the rocks is not as pronounced as reported and that the structure appears to be made out of solid rock rather than distinct blocks, which would suggest human activity. Furthermore, they argue that the alleged carvings are naturally occurring scratches.

Coral Reef (Ningaloo Coast)

By alexstokes25

(2022-09-05)

The Ningaloo Coast is a World Heritage Site located on Western Australia's remote coast along the East Indian Ocean. The interconnected ocean and arid coast form aesthetically striking landscapes and seascapes. The coastal waters host a major near shore reef system and a directly adjacent limestone karst system and associated habitats and species along an arid coastline. The property holds a high level of terrestrial species endemism and high marine species diversity and abundance. An estimated 300 to 500 whale sharks aggregate annually coinciding with mass coral spawning events and seasonal localized increases in productivity. The marine portion of the nomination contains a high diversity of habitats that includes lagoon, reef, open ocean, the continental slope and the continental shelf. Intertidal systems such as rocky shores, sandy beaches, estuaries, and mangroves are also found within the property. The most dominant marine habitat is the Ningaloo reef, which sustains both tropical and temperate marine fauna and flora, including marine reptiles and mammals.

The main terrestrial feature of the Ningaloo Coast is the extensive karst system and network of underground caves and water courses of the Cape Range. The karst system includes hundreds of separate features such as caves, dolines and subterranean water bodies and supports a rich diversity of highly specialized subterranean species. Above ground, the Cape Range Peninsula belongs to an arid ecoregion recognized for its high levels of species richness and endemism, particularly for birds and reptiles.

School and/or Shoal of Fish

By alexstokes25

(2022-09-04)

To the surprise of many, there are actually two types of fish aggregations: shoals and schools. A shoal is a looser group, sometimes consisting of different species that hang out together (often temporarily) but are not organized. On the other hand, schools are notoriously highly structured with coordinated movements and a common direction. A group of fish can switch from shoaling to schooling and back again. Schooling seems to have evolved as a defense against predators and in some cases as a way to increase feeding efficiency. Every fish in a school must execute perfectly to get the best results.

Stingray (Great Barrier Reef)

By alexstokes25

(2022-09-04)

Stingrays are a group of sea rays, which are cartilaginous fish related to sharks. They are classified in the suborder Myliobatoidei of the order Myliobatiformes and consist of eight families: Hexatrygonidae, Plesiobatidae, Urolophidae, Urotrygonidae, Dasyatidae, Potamotrygonidae, Gymnuridae and Myliobatidae.

One of Australia’s most remarkable natural gifts, the Great Barrier Reef is blessed with the breathtaking beauty of the world’s largest coral reef. The reef contains an abundance of marine life and comprises of over 3000 individual reef systems and coral cays and literally hundreds of picturesque tropical islands with some of the worlds most beautiful sun-soaked, golden beaches. Because of its natural beauty, the Great Barrier Reef has become one of the worlds most sought after tourist destinations.

Shark at Tubbatha Reef

By kkeps

(2017-03-13)

The Tubbataha Natural Park, AKA the Tubbataha Reefs Natural Park (Filipino: Bahurang Tubbataha), is a protected area of the Philippines in the middle of the Sulu Sea. The marine and bird sanctuary consists of 2 atolls and the smaller Jessie Beazley Reef covering a total area of 239,800 ac. The uninhabited islands and reefs are part of the island municipality of Cagayancillo, about 130 km NE of the reef.

In 1993, the UNESCO declared the Tubbataha Reefs National Park a World Heritage Site as a unique example of an atoll reef with a very high density of marine species; the North Islet serving as a nesting site for birds and marine turtles. The site is an excellent example of a pristine coral reef with a spectacular 100-m perpendicular wall, extensive lagoons and two coral islands. In 1999, Ramsar listed Tubbataha as one of the wetlands of international importance. In 2008, the reef was nominated at New7Wonders of Nature.

Coral reef in Eilat.

By Mike1989

(2013-01-20)

The coral reef in Eilat extends for over 1200 meters along the shore, and is one of the northernmost reefs in the world, and the only one of its kind in Israel and as such has been declared a nature reserve. The reef has become a pilgrimage site for sea naturalists and for professional and amateur divers and snorkelers. The reef is made up of a primary wall of coral that descends to a depth of 3 to 4 meters. Behind this is a sand bar with two huge rocks known as Joshua and Moses, and behind these is another steep wall of coral that descends to a depth of 35 meters. The beautiful coral creates colorful garden-like formations containing many varieties of fish and marvelous sea creatures. There are over 270 species of coral in this underwater jungle, among which are numerous small habitats that contain over 2,500 species of underwater life – some of them unique to the Red Sea. These include sea turtles, sea urchins, oysters, sea anemones, crabs, sponges, octopi, cuttlefish, tropical fish, and even several types of cheerful dolphins - making diving at the site a special experience.

Kingman Reef

By AlbinoFlea

(2006-01-18)

From Wikipedia:

Kingman Reef is a one-square-kilometer tropical coral reef located in the North Pacific Ocean, roughly half way between Hawaiian Islands and American Samoa at 6°24′N 162°24′W. It is the northernmost of the Northern Line Islands and an unincorporated territory of the United States, part of the United States Minor Outlying Islands, administered from Washington, DC by the U.S. Navy. The reef is closed to the public.

It was found in 1789 by Captain Edmund Fanning of the ship Betsey. Captain W.E. Kingman described it in 1853. It was formally annexed to the United States on May 10, 1922.

Kingman is about 920 nautical miles south of Honolulu.

At times, its shoreline might reach three kilometers in circumference, but the highest point on the reef is about one meter above sea level and wetted or awash most of the time, making Kingman Reef a maritime hazard. It has no natural resources, is uninhabited, and supports no economic activity. The reef partly encloses a deep interior lagoon that was used in 1937 and 1938 as a halfway station between Hawai'i and American Samoa by Pan American Airways flying boats. In 1937, Pan Am had plans to anchor the ship North Wind as a floating tanker at Kingman and use the reef as a stopover for its flying boats on the route to New Zealand but Pan Am abandoned the idea finding the costs of supporting a mostly idle tanker ship prohibitive. There were also concerns that comfortable overnight accommodations would not be available in the event of a mechanical breakdown. As a result, Pan Am switched to Canton Island on May 18, 1939 and began service to New Zealand on July 12, 1940.
