Irukandji Jellyfish
The Irukandji jellyfish ( ) are any of several similar, extremely venomous species of rare box jellyfish. With a very small adult size of about a cubic centimetre (1 cm3 or 0.061 in3), they are both one of the smallest and one of the most venomous jellyfish in the world. They inhabit the northern marine waters of Australia, and cost the Australian government $AUD 3 billion annually through tourism losses and medical costs associated with stings. This type of jellyfish reproduces sexually with eggs and sperm. They fire their stingers into their victim, causing a condition known in humans as Irukandji syndrome, which can be fatal and difficult to immediately recognise due to the delayed effects of the venom. There are about 16 known species of Irukandji, of which '' Carukia barnesi'', '' Malo kingi'', '' Malo maxima'', '' Malo filipina'' and '' Malo bella'' are the best known.Crew, Becky"The Smallest and Deadliest Kingslayer in the World" October 7, 2013, ''Scientific A ...

Malo (jellyfish)
''Malo'' is one of a genus of box jellies in the family Carybdeida in the Phylum Cnidaria. It has four known species, three of which were described by the Australian marine biologist Lisa-Ann Gershwin. The genus was discovered in 2005. Many of the species are known for their paralytic and deadly affect. Many species in the ''Malo'' genus are very small and hard to capture and study. Many species of ''Malo'' have been captured on the Western and Eastern cost of Australia. ''Malo'' appear to be solidarity jellies. Etymology The name Malo is derived by the first two letters of the name of Mark Longhurst, who survived a severe sting by a jellyfish apparently from the genus shortly before the publication of its discovery. The author, Gershwin, also noted the "interesting coincidence that the word “malo” is Spanish for “bad”, as this species is presumed to be capable of lethal envenomation. Gender masculine."

Venom
Venom or zootoxin is a type of toxin produced by an animal that is actively delivered through a wound by means of a bite, sting, or similar action. The toxin is delivered through a specially evolved ''venom apparatus'', such as fangs or a stinger, in a process called ''envenomation''. Venom is often distinguished from ''poison'', which is a toxin that is passively delivered by being ingested, inhaled, or absorbed through the skin, and ''toxungen'', which is actively transferred to the external surface of another animal via a physical delivery mechanism. Venom has evolved in terrestrial and marine environments and in a wide variety of animals: both predators and prey, and both vertebrates and invertebrates. Venoms kill through the action of at least four major classes of toxin, namely necrosis, necrotoxins and cytotoxins, which kill cells; neurotoxins, which affect nervous systems; myotoxins, which damage muscles; and Hemotoxin, haemotoxins, which disrupt Thrombus, blood clotti ...

Nail (anatomy)
A nail is a protective plate characteristically found at the tip of the digit (anatomy), digits (fingers and toes) of all primates, corresponding to the claws in other tetrapod animals. Fingernails and toenails are made of a tough rigid protein called alpha-keratin, a polymer also found in the claws, hooves, and horn (anatomy), horns of vertebrates. Structure The nail consists of the nail plate, the nail matrix and the nail bed below it, and the grooves surrounding it. Parts of the nail The nail matrix is the active Tissue (biology), tissue (or Germ layer, germinal Matrix (biology), matrix) that generates cells. The cells harden as they move outward from the nail root to the nail plate. The nail matrix is also known as the ''matrix unguis'', keratogenous membrane, or onychostroma. It is the part of the nail bed that is beneath the nail and contains nerves, lymph, and blood vessels. The matrix produces cells that become the nail plate. The width and thickness of the nail p ...

Irukandji Syndrome
Irukandji syndrome is a condition that results from envenomation by certain box jellyfish. In rare instances the sting may result in cardiac arrest and death. The most common jellyfish involved is the '' Carukia barnesi'', a species of Irukandji jellyfish. Those stung may experience severe or even excruciating pain. The syndrome was given its name in 1952 by Hugo Flecker, after the Aboriginal Irukandji people who live in Palm Cove, north of Cairns, Queensland, Australia, where stings are common. Signs and symptoms Most stings occur during the summer wet season in October–May in North Queensland, with different seasonal patterns elsewhere. Because the jellyfish are very small, the venom is only injected through the tips of the nematocysts (the cnidocysts) rather than the entire lengths; as a result the sting may barely be noticed at first. It has been described as feeling like little more than a mosquito bite. The symptoms, however, gradually become apparent and then mor ...

Port Douglas, Queensland
Port Douglas is a coastal town and locality in the Shire of Douglas, Queensland, Australia, approximately north of Cairns. In the , the locality of Port Douglas had a population of 3,650 people. The town's population can often double, however, with the influx of tourists during the peak tourism season from May to September. The town is named in honour of a former Premier of Queensland, John Douglas. Port Douglas developed quickly based on the mining industry. Other parts of the area were established with timber cutting in the area surrounding the Daintree River and with settlement starting on lots around the Mossman River by 1880. Previous names for the town included Terrigal, Island Point, Port Owen and Salisbury. The town is situated adjacent to two World Heritage areas, the Great Barrier Reef and the Daintree Rainforest. Port Douglas was No. 3 on Australian Traveller magazine's list of 100 Best Towns in Australia."100 Best Towns in Australia". Retrieved 21 July 2013 ...

Nematocyst
A cnidocyte (also known as a cnidoblast) is a type of cell containing a large secretory organelle called a ''cnidocyst'', that can deliver a sting to other organisms as a way to capture prey and defend against predators. A cnidocyte explosively ejects the toxin-containing cnidocyst which is responsible for the stings delivered by a cnidarian. The presence of this cell defines the phylum Cnidaria, which also includes the corals, sea anemones, hydrae, and jellyfish. Cnidocytes are single-use cells that need to be continuously replaced. Structure and function Each cnidocyte contains an organelle called a cnidocyst, which consists of a bulb-shaped capsule and a hollow, coiled tubule that is contained within. Immature cnidocytes are referred to as cnidoblasts or nematoblasts. The externally oriented side of the cell has a hair-like trigger called a cnidocil, a mechano-chemical receptor. When the trigger is activated, the tubule shaft of the cnidocyst is ejected and, in the case ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it, with more than 150 Nobel Prize-winners being featured since its inception. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter (painter), Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large-format New York City newspaper was released on August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the United States Patent and Trademark Office, U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 devi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carukiidae
Carukiidae is a family of box jellyfish within the Cubozoa class. Carukiidae can be easily classified by their lack of cirri clumps inside the cubozoan stomach, as well as the size and the placement of their nematocysts. Carukiidae use nematocysts as a defense mechanism; they releases a venom from the tips of their nematocysts, producing the Irukandji syndrome Irukandji syndrome is a condition that results from envenomation by certain box jellyfish. In rare instances the sting may result in cardiac arrest and death. The most common jellyfish involved is the '' Carukia barnesi'', a species of Irukand .... Even though positions of spines on the shaft of the Carukiidae cause illness, there are areas on the body that do not. The rhopalial niche openings, which discern light, do not incur any illness. The Carukiidae also have non-venomous rhopaliar horns, which are imperceptive in function and located above the rhopalial niches. Irukandji syndrome triggered by Carukiidae requ ...

Animals Described In 2007
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (). With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology. The animal kingdom is divided into five major clades, namely Porifera, Ctenophora, Placozoa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
