Cymothoa exigua is a tiny crustacean that sneaks up on a fish (specifically, a red snapper) and works its way in through the gills. Typical parasite behavior so far.
Then it attaches itself to the base of the fish's tongue, the tongue evidently being the tastiest part of the fish (get it!?). The parasite uses its claws to dig into the tongue and drink the fish's blood--and that's just the beginning
Cymothoa Exigua in Human
It is currently believed that Cymothoa Exigua are not harmful to humans unless picked up alive, in which case they can bite.
A tongue-eating parasite inside the mouth of a red snapper purchased from a London fishmonger recently revolted its buyer and fascinated scientists.
Previously, scientists believed fish infected with the parasite, nicknamed the "tongue louse," existed solely in the Gulf of California. The find in England suggests the parasite's range may be expanding, according to a recent press release issued by a museum in England.
But does the Cymothoa mouth-squatter leave its fishy friend tongueless? Of course not. It does what any crafty parasite would do and replaces the old tongue with its own body.
The fish is actually able to use the parasite just like a normal tongue, only it has to share all the food with its new friend. Yes, the whole foster-tongue thing seems like a pretty nice gesture on the part of ol' Cymothoa until you remember there was nothing wrong with the fish's old tongue in the first place.
Cymothoa Exigua Life cycle
Not much is known about the life cycle of Cymothoa Exigua. It exhibits sexual reproduction. It is likely that juveniles first attach to the gills of a fish and become males. As they mature, they become females, with mating likely occurring on the gills. If there is no female present, within a pair of two males, one male can turn into a female after it grows to 10mm in length. The female then makes its way to the fish's mouth where it uses its front claws to attach to the fish’s tongue.
Adrenal Insufficiency Causes, Symptoms and Treatment Autoimmune adrenalitis is the most common cause of primary adrenal insufficiency. Adrenalitis caused by tuberculosis was once the most common cause. Autoimmune adrenalitis is sometimes accompanied by other autoimmune endocrine deficiencies, such as thyroid disease, diabetes mellitus, pernicious anemia, hypoparathyroidism, or ovarian failure (Table 14). Recently, AIDS and antiphospholipid syndrome have been cited as additional causes.
Iatrogenic tertiary adrenal insufficiency, a common secondary cause of adrenal insufficiency, results from suppression of hypothalamic-pituitary-adrenal function secondary to glucocorticoid administration. Secondary adrenal insufficiency may also result from pituitary or hypothalamic disease, as described earlier.
Plantar Fasciitis Treatment The plantar fascia can be involved with plantar fasciitis as it inserts into the calcaneus and also the Achilles tendon as it inserts into the back of the calcaneus. These are very common problems. If there is any sense that it is chronic inflammatory in nature and there are other systems involved, really think of a spondyloarthropathy because these areas are very commonly involved with things like ankylosing spondylitis and the like. But I do see patients occasionally and that’s all they have. They just have Achilles tendonitis or plantar fasciitis. Sometimes you can even get bursal inflammation although it’s very difficult to differentiate from direct tendon involvement. But plantar fasciitis, again the most common situation I see is someone who walks a lot. Mail carriers. They start out with a 50 pound bag of mail and it’s hard on their feet. They just walk around and deliver mail all day. But anybody who is on their feet a lot, walking, carrying extra weight, and the pain is usually in the sort of medial aspect of the bottom of the calcaneus. It’s not dead center, because that’s not where the plantar fascia inserts.
Dissociative amnesia is inability to recall important personal information, usually of a traumatic or stressful nature, that is too extensive to be explained by ordinary forgetfulness and is not due to the direct effects of substance use or a neurological or other general medical condition. Five types of disturbance in recall have been described. In the following examples, the individual is involved in a traumatic automobile accident in which a loved one is killed.
The Scope of Noise Exposure Noise is especially prevalent in the manufacturing industries. The US
Department of Labor has estimated that 19.3% of the workers in manufacturing and
utilities are exposed to daily average noise level of 90 dBA an above, 34.4% are
exposed to levels above 85 dBA, and 53.1% to levels above 80 dBA.
These estimates should be fairly typical of the percentage of workers exposed
to hazardous level of noise in other nations. The levels are likely to be
somewhat higher in less developed nations, where engineering controls are not
used as widely, and somewhat lower in nations with stronger noise control
programmes, such as Scandinavian Country and Germany.
Heat Stroke Prevention Tips Each summer we hear about athletes suffering serious heat illness, particularly heat stroke, during recreational running events, marathons and fun runs. In order to prevent becoming a statistic, it's helpful to learn about the most common types of heat illness and take precautions if you exercise in hot weather. Here is some tips for heat stroke prevention.
Filariasis Symptoms and Treatment The species of mosquitoes that transmit malaria and yellow fever, disease caused by protozoa and viruses, also transmit filariasis, caused by a parasitic worm—a nematode or roundworm. Filariasis affects 300 million people living in tropical and subtropical areas of the world. The worm invades the subcutaneous tissues and lymph system of the human body, blocking the flow lymph and producing symptoms of inflammation, edema, abscesses, and, in one form of the disease, blindness. Filariasis is not unknown to Americans; some 15,000 soldiers contracted disease during World War II fighting in the Pacific Theater, and cases have been reported along the Carolina coast area. But most of the victims of filariasis live in a region extending from Africa through Asia to the islands of New Guinea and Borneo.
How to Reduce Fever Fast in a child Fever in Infants and Children
A normal temperature is about 98.6°F (37°C) when taken orally (in your child’s mouth) and 99.6°F (37.5°C) when taken rectally (in your child’s bottom). Many doctors define a fever as an oral temperature above 99.5°F (37.5°C) or a rectal temperature above 100.4°F (38°C).
Syphilis types symptoms and treatment Syphilis, the other well-known sexually transmitted disease, is also caused by a bacterial organism, the spirochete known as Treponema pallidum. Because it s extremely delicate and dies readily upon exposure to air, dryness, or cold, the organism is generally transferred only through direct sexual contact. Typically, this means contact between sexual organs during intercourse, but in rare instances, the organism enters the body through a break in the skin, through deep kissing in which body fluids are exchanged, or through some other transmission of body fluids.
Blood type diet chart and list Are you looking for blood type diet chart? The blood type diet is a diet advocated by Peter D'Adamo, a naturopathic physician, and outlined in his book Eat Right 4 Your Type. D'Adamo's claim is that ABO blood type is the most important factor in determining a healthy diet, and he promotes distinct diets for people with O, A, B, and AB blood types.
One criticism of D'Adamo's hypotheses and recommendations claims that he provided inadequate evidence. For example, his first book, Eat Right 4 Your Type, published in 1997, contains only a bibliography. While his subsequent books have provided thorough references for the classifications of various foods within his categories of "beneficials", "neutrals" and "avoids", his specific process and reasons for reaching these conclusions of classification remain undocumented.

The body tissue, organs, and systems are located either inside the cavities formed by the skeleton or around it. The skeleton is the framework that holds everything in place. Also it source of attachment for many of the organs.
