Cephalopod Attack
Cephalopod attacks on humans have been reported since ancient times. A significant portion of these attacks are questionable or unverifiable tabloid stories. Cephalopods are members of the class Cephalopoda, which includes all squid, octopuses, cuttlefish, and nautiluses. Some members of the group are capable of causing injury or death to humans. Defenses Tentacles Tentacles are the major limbs used by squid for defense and hunting. They are often confused with arms—octopuses have eight arms, while squid and cuttlefish have eight arms and two tentacles. These tentacles are generally longer than arms and typically have suckers only on their ends instead of along the entire length. The giant squid and colossal squid have some of the largest tentacles in the world, with suckers capable of producing suction forces of more than ) and with pointed teeth at the tips. Beak The cephalopod beak resembles that of a parrot. It is a tough structure made of chitin and marks the beginn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giant Octopus Attacks Ship
In folklore, giants (from Ancient Greek: ''gigas'', cognate giga-) are beings of human-like appearance, but are at times prodigious in size and strength or bear an otherwise notable appearance. The word ''giant'' is first attested in 1297 from Robert of Gloucester's chronicle. It is derived from the ''Gigantes'' ( grc-gre, Γίγαντες) of Greek mythology. Fairy tales such as ''Jack the Giant Killer'' have formed the modern perception of giants as dimwitted ogres, sometimes said to eat humans, while other giants tend to eat the livestock. The antagonist in ''Jack and the Beanstalk'' is often described as a giant. In some more recent portrayals, like those of Jonathan Swift and Roald Dahl, some giants are both intelligent and friendly. Literary and cultural analysis Giants appear in the folklore of cultures worldwide as they represent a relatively simple concept. Representing the human body enlarged to the point of being monstrous, giants evoke terror and remind humans of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rostrum (anatomy)
Rostrum (from Latin ', meaning ''beak'') is a term used in anatomy for a number of phylogenetically unrelated structures in different groups of animals. Invertebrates * In crustaceans, the rostrum is the forward extension of the carapace in front of the eyes. It is generally a rigid structure, but can be connected by a hinged joint, as seen in Leptostraca. * Among insects, the rostrum is the name for the piercing mouthparts of the order Hemiptera as well as those of the snow scorpionflies, among many others. The long snout of weevils is also called a rostrum. * Gastropod molluscs have a rostrum or proboscis. * Cephalopod molluscs have hard beak-like mouthparts referred to as the rostrum.

Enteroctopus Dolfeini
The giant Pacific octopus (''Enteroctopus dofleini''), also known as the North Pacific giant octopus, is a large marine cephalopod belonging to the genus ''Enteroctopus''. Its spatial distribution includes the coastal North Pacific, along Mexico (Baja California), The United States (California, Oregon, Washington, and Alaska), Canada (British Columbia), Russia, Eastern China, Japan, and the Korean Peninsula. It can be found from the intertidal zone down to , and is best adapted to cold, oxygen-rich water. It is the largest octopus species, based on a scientific record of a individual weighed live. Etymology The specific name ''dofleini'' was chosen by Gerhard Wülker in honor of German scientist Franz Theodor Doflein. It was moved to genus ''Enteroctopus'' by Eric Hochberg in 1998. Description Size ''E. dofleini'' is distinguished from other species by its large size. Adults usually weigh around , with an arm span up to .

Octopus Wrestling
Octopus wrestling involves a diver grappling with a large octopus in shallow water and dragging it to the surface.Norman, M.D. (2000). Octopus Wrestling. In: ''Cephalopods: A World Guide''. ConchBooks, pp. 217-218. Although it was called "wrestling", it was not wrestling per se, as most octopuses are rather skittish and not aggressive at all unless they are provoked, with most cases of provocation ending with the octopus fleeing. The contestants were usually only searching in holes along rocks in the ocean to grab the head of an octopus. Once a diver caught an octopus he continued to pull until the animal gave up. History An early article on octopus wrestling appeared in a 1949 issue of ''Mechanix Illustrated''. A report from the Toledo Blade said that in 1957, 200 people gathered to watch an octopus wrestling event in the Puget Sound near Tacoma, Washington. A team from Portland, Oregon, won the contest by catching an eighty-pound octopus. Octopus wrestling reached the heig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staten Island
Staten Island ( ) is a borough of New York City, coextensive with Richmond County, in the U.S. state of New York. Located in the city's southwest portion, the borough is separated from New Jersey by the Arthur Kill and the Kill Van Kull and from the rest of New York by New York Bay. With a population of 495,747 in the 2020 Census, Staten Island is the least populated borough but the third largest in land area at . A home to the Lenape indigenous people, the island was settled by Dutch colonists in the 17th century. It was one of the 12 original counties of New York state. Staten Island was consolidated with New York City in 1898. It was formally known as the Borough of Richmond until 1975, when its name was changed to Borough of Staten Island. Staten Island has sometimes been called "the forgotten borough" by inhabitants who feel neglected by the city government. The North Shore—especially the neighborhoods of St. George, Tompkinsville, Clifton, and Stapleton—i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victor Hugo
Victor-Marie Hugo (; 26 February 1802 – 22 May 1885) was a French Romantic writer and politician.

Frederick O'Brien
Frederick O'Brien (16 June 1869 – 9 January 1932) was an American author, journalist, hobo, peripatetic world traveler, and public administrator. He wrote three best-selling travel books about French Polynesia between 1919 and 1922: ''White Shadows in the South Seas, Mystic Isles of the South Seas,'' and ''Atolls of the Sun.'' A movie was made in 1928 of ''White Shadows in the South Seas''. Early life Frederick O'Brien was born in 1869 in Baltimore into a comfortable Irish Catholic family. Family beliefs tended to leftist activism and outrage over social injustice. He referred to his devout sister Mary as a Catholic Trotskyite for her radicalism. Following three years at Loyola Jesuit College, he dropped out to travel. He spent 1887 exploring Venezuela and Brazil by foot, and worked in asphalt pits in Trinidad. Returning home, he studied law briefly, "plodding through irksome duties as a law clerk." Setting out again as a self-proclaimed hobo, he traveled throughout the Stat ...

Alfred Brehm
Alfred Edmund Brehm (; 2 February 1829 – 11 November 1884) was a German zoologist, writer, director of zoological gardens and the son of Christian Ludwig Brehm, a famous pastor and ornithologist. Through the book title ''Brehms Tierleben'', which he co-authored with Eduard Pechuël-Loesche, Wilhelm Haacke, and Richard Schmidtlein, his name became a household word for popular zoological literature. Early life Alfred Brehm grew up in the small Thuringian village of Unter renthendorf as the son of the minister, Christian Ludwig Brehm, and of his second wife Bertha. Christian Ludwig Brehm made a name for himself as an ornithologist by publications and through an extensive collection of stuffed birds. The collection, held in the parsonage and consisting of over 9,000 dead birds, offered a glimpse into the world of European birds. His father's research gave the younger Brehm an interest in zoology, but at first he wanted to become an architect. In the spring of 1844 he ...

Octopus Vulgaris Merculiano
An octopus ( : octopuses or octopodes, see below for variants) is a soft-bodied, eight- limbed mollusc of the order Octopoda (, ). The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the center point of the eight limbs. The soft body can radically alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates. Octopuses inhabit various regions of the ocean, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature early, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Respiratory Arrest
Respiratory arrest is a sickness caused by apnea (cessation of breathing) or respiratory dysfunction severe enough it will not sustain the body (such as agonal breathing). Prolonged apnea refers to a patient who has stopped breathing for a long period of time. If the heart muscle contraction is intact, the condition is known as respiratory arrest. An abrupt stop of pulmonary gas exchange lasting for more than five minutes may permanently damage vital organs, especially the brain. Lack of oxygen to the brain causes loss of consciousness. Brain injury is likely if respiratory arrest goes untreated for more than three minutes, and death is almost certain if more than five minutes. Damage may be reversible if treated early enough. Respiratory arrest is a life-threatening medical emergency that requires immediate medical attention and management. To save a patient in respiratory arrest, the goal is to restore adequate ventilation and prevent further damage. Management interventions inc ...

Tetrodotoxin
Tetrodotoxin (TTX) is a potent neurotoxin. Its name derives from Tetraodontiformes, an order that includes pufferfish, porcupinefish, ocean sunfish, and triggerfish; several of these species carry the toxin. Although tetrodotoxin was discovered in these fish and found in several other animals (e.g., in blue-ringed octopuses, rough-skinned newts, and moon snails), it is actually produced by certain infecting or symbiotic bacteria like ''Pseudoalteromonas'', ''Pseudomonas'', and ''Vibrio'' as well as other species found in animals. Tetrodotoxin is a sodium channel blocker. It inhibits the firing of action potentials in neurons by binding to the voltage-gated sodium channels in nerve cell membranes and blocking the passage of sodium ions (responsible for the rising phase of an action potential) into the neuron. This prevents the nervous system from carrying messages and thus muscles from contracting in response to nervous stimulation. Its mechanism of action, selective blocking o ...
