Blowfish Diagram
Tetraodontidae is a family of primarily marine and estuarine fish of the order Tetraodontiformes. The family includes many familiar species variously called pufferfish, puffers, balloonfish, blowfish, blowies, bubblefish, globefish, swellfish, toadfish, toadies, toadle, honey toads, Haaris Anwar fish, sugar toads, and sea squab. They are morphologically similar to the closely related porcupinefish, which have large external spines (unlike the thinner, hidden spines of the Tetraodontidae, which are only visible when the fish have puffed up). The scientific name refers to the four large teeth, fused into an upper and lower plate, which are used for crushing the hard shells of crustaceans and mollusks, their natural prey. The majority of pufferfish species are toxic and some are among the most poisonous vertebrates in the world. In certain species, the internal organs, such as the liver, and sometimes the skin, contain tetrodotoxin, and are highly toxic to most animals when eat ...

Lutetian
The Lutetian is, in the geologic timescale, a stage or age in the Eocene. It spans the time between . The Lutetian is preceded by the Ypresian and is followed by the Bartonian. Together with the Bartonian it is sometimes referred to as the Middle Eocene Subepoch. Stratigraphic definition The Lutetian was named after Lutetia, the Latin name for the city of Paris. The Lutetian Stage was introduced in scientific literature by French geologist Albert de Lapparent in 1883 and revised by A. Blondeau in 1981. The base of the Lutetian Stage is at the first appearance of the nanofossil ''Blackites inflatus'', according to an official reference profile (GSSP) established in 2011. Of two candidates located in Spain, the Gorrondatxe section was chosen.See thwebsite of Eustoquio Molinafor these candidates. The top of the Lutetian (the base of the Bartonian) is at the first appearance of calcareous nanoplankton species ''Reticulofenestra reticulata''. The Lutetian overlaps with the Geisel ...

Pufferfish Mating Ritual
The white-spotted pufferfish (''Torquigener albomaculosus'') is known for its unique and complex courtship display which involves creating large, geometric circles in the sand. These circles are constructed in an effort to attract females for copulation. Males must maintain their circles in order to attract a mate. A female will evaluate the structure and choose to mate with the males after evaluation and completion of other mating behaviors. The geometric circles had first been noticed by divers in 1995, but it was not discovered that they were created by white-spotted pufferfish until 2013 when the species was discovered in the Ryukyu Islands. It is thought that white-spotted pufferfish are the only species of their kind to engage in this type of mating ritual. Discovery The white-spotted pufferfish is a relatively small (10 cm) fish that was named in 2014 by a research group for the National Museum of Nature and Science. The fish has a brownish-yellow body with white ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Torquigener Albomaculosus
''Torquigener albomaculosus'', or the white-spotted pufferfish, is the 20th discovered species of the genus '' Torquigener''. The species was discovered in the ocean waters around the Ryukyu Islands in Japan off the south coast of Amami Ōshima Island. Observed depths of the species range between . The fish's head and body are colored brown with white spots at the back. Its abdomen is silvery-white with white spots. The males are known for creating circular nests as part of their mating ritual in the sand, measuring in diameter. Such nest designs were noticed since 1995, but their creation remained a mystery until the species' discovery. The nests are created to attract mates through the nest's impressive design and ability to gather fine sand particles, both of which influence a female's mate choice. Males never reuse a nest. As of 2014, the white-spotted pufferfish is thought to be the only species that creates these shapes. In 2015, the International Institute for Species ...

Chesapeake Bay
The Chesapeake Bay ( ) is the largest estuary in the United States. The Bay is located in the Mid-Atlantic (United States), Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula (including the parts: the Eastern Shore of Maryland / Eastern Shore of Virginia and the state of Delaware) with its mouth of the Bay at the south end located between Cape Henry and Cape Charles (headland), Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the Bay's drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) and all of District of Columbia. The Bay is approximately long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Puffer
The northern puffer, ''Sphoeroides maculatus'', is a species in the family Tetraodontidae, or pufferfishes, found along the Atlantic coast of North America. Unlike many other pufferfish species, the flesh of the northern puffer is not poisonous (its viscera can contain poison). They are commonly called sugar toads in the Chesapeake Bay region, where they are eaten as a delicacy, it can even be eaten raw as long as its meat is properly cleaned. In much of the Northeast, the fish is known simply as "blowfish" or "chicken of the sea". Description The northern puffer is a club-shaped fish with a gray, brown, or olive back and a yellow or white belly. Adults have small spines covering the entire body with a tiny beak-like mouth. Its color is poorly defined black/dark green spots and saddles and a yellow to white belly. It has tiny jet-black pepper spots (about 1 mm in diameter) scattered over most of pigmented surface, particularly evident on cheeks. Lower sides of the body have ...

Korea
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the "Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fugu
The fugu (; ; ) in Japanese, ''bogeo'' (; 鰒魚) or ''bok'' () in Korean, and ''hétún'' (河豚; 河魨) in Standard Modern Chinese is a pufferfish, normally of the genus ''Takifugu'', ''Lagocephalus'', or ''Sphoeroides'', or a porcupinefish of the genus ''Diodon'', or a dish prepared from these fish. Fugu can be lethally poisonous to humans due to its tetrodotoxin, meaning it must be carefully prepared to remove toxic parts and to avoid contaminating the meat. The restaurant preparation of fugu is strictly controlled by law in Japan and several other countries, and only chefs who have qualified after three or more years of rigorous training are allowed to prepare the fish. Domestic preparation occasionally leads to accidental death. Fugu is served as sashimi and nabemono. The liver was served as a traditional dish named ''fugu-kimo'', being widely thought to be a tasty part, but it is also the most poisonous, and serving this organ in restaurants was banned in Japan in 198 ...
