但2005年時,有人在英國捕獲的一條
魚的嘴里,也發(fā)現(xiàn)了它的身影—這似乎說明,縮頭魚虱可能已散布到世界上的很多地方。但至今為止,人們對這種體長約3-4厘米的寄生蟲的完整生活史仍然了解有限??s頭魚虱主要寄生在魚類的體表、口腔和鰓腔,有時會鉆入魚的肌肉組織中。目前的研究發(fā)現(xiàn),縮頭魚虱的幼體首先附著到魚鰓上,長成雄性個體(縮頭水虱科的物種通常是雄性先成熟的雌雄同體);成熟之后縮頭魚虱變成雌性,然后在魚鰓上完成交配;之后雌蟲會穿過魚鰓進入到魚的口腔,用鉤狀的前端足緊緊抓住魚舌,開始吸取血液直至其*萎縮;接下來,縮頭魚虱就取代了舌頭,與那只可憐的魚一起共度余生。它們一方面會以魚的血液為食,另一方面會吸取魚的黏液—這是一種*取代寄主器官的寄生方式。但縮頭魚虱也并不*依賴寄生生活,它們有一定的游泳和攝食能力,在不利環(huán)境下,還會更換寄主??s頭魚虱對寄主的傷害顯而易見。除了讓寄主沒了舌頭,當它們寄生在其他位置時,還會帶來包括組織損傷、貧血、體重下降、生長緩慢、死亡率上升等傷害。但不同種類對寄主的傷害程度不同。不過科學家們相信,這種生物對人類并沒有任何危害。(縮頭水虱科的物種通常是雄性先成熟的雌雄同體)之后雌蟲穿過魚鰓進入到魚的口腔,用鉤狀的前端足緊緊抓住魚舌,開始吸取血液直至其*萎縮。接下來,縮頭魚虱就占據(jù)了魚舌的位置,與那只可憐的魚一起共度余生。
借由后部的腹肢附著在魚舌的殘余部分,縮頭魚虱也“仗義”地承擔起了魚舌的責任??茖W家推測,這種等足目寄生蟲實現(xiàn)了對魚體器官的機械替換,除此之外,似乎并不產(chǎn)生其他的傷害。取代魚舌之后,縮頭魚虱仍會以魚的血液為食,但更多的是吸取魚分泌的黏液。這是人們*次發(fā)現(xiàn)能*取代寄主器官的寄生方式。
縮頭魚虱長約3-4厘米。它們會從墨西哥笛鯛的鰓進入到其體內,依附在舌根中。它們的前爪會抽走舌頭
上的血液,使其萎縮。它們會依附在舌頭的肌肉上取而代之。墨西哥笛鯛仍能像使用正常舌頭般使用
頭魚虱。縮頭魚虱似乎并不會對魚的身體造成其他傷害。當縮頭魚虱取代舌頭后,它們一方面會以魚的血液為食,另一方面吸取魚的黏液。這是*已知*取代寄主器官的寄生方式?,F(xiàn)時相信縮頭魚虱對人類并沒有危害。
在幼蟲時進入魚類的口腔內,通過魚的舌頭吸食魚的血液,直到魚的舌頭萎縮。然后將自己的尾部與已經(jīng)萎縮的魚舌連接起來代替魚舌工作,由寄生轉為共生的甲殼動物。
But in 2005, someone caught a piece in the UK
It's also found in the fish's mouth - which seems to suggest that the head-louse may have spread to many parts of the world. So far, however, there is still limited understanding of the complete life history of such parasites about 3-4 centimeters in length. Fish head lice are mainly parasitic on the fish's body surface, mouth and gill cavity, sometimes into the fish's muscle tissue. The current study found that the larvae of the first-stage louse lice are first attached to the gills of the fish and grow into male individuals (the species of the reduced-water lice is usually the males and herds); mature lice become females after maturation, and then The mating is done on the gill of the fish; afterwards, the females pass through the gills of the fish and enter the mouth of the fish, grasping the fish tongue with the hooked forefoot and gripping the fish until it compley atrophies. Next, Replace the tongue, spend the rest of your life with that poor fish. They feed on the fish's blood on the one hand, and fish's mucus on the other - a parasitic way of compley replacing the host organism. However, the false-headed louse does not depend entirely on the parasitic life, they have some swimming and feeding ability, in adverse circumstances, but also change the host. False head louse damage to the host is obvious. In addition to letting the host tongueless, when they are parasitic elsewhere, there is also damage including tissue damage, anemia, weight loss, slow growth and increased mortality. However, different types of damage to the host is different. However, scientists believe that this creature does not harm humans. (Phylloxeneidae species is usually male first maturity hermaphrodite), the females enter the mouth of the fish through the fish gills and hold the fish tongue firmly with the hooked forefoot and begin to aspirate the blood until it is compley atrophied. Next, the head louse occupy the position of the fish tongue, spend the rest of his life with the poor fish.
With the posterior abdominal limbs attached to the remnants of the fish tongue, the false-headed fish lice are also "generous" to take responsibility for the fish tongue. Scientists speculate that this Isopodal parasites do mechanical replacement of fish organs, in addition, it seems does not produce other injuries. After replacing the fish tongue, fish head louse still feed on the blood of the fish, but more is the mucus secreted by fish. This is the first time people have found that parasites can compley replace the host organism.
False head lice about 3-4 cm long. They enter the body from the gills of the Mexican snapper and attach to the base of the tongue. Their forepaws will take away their tongue
On the blood, make it shrink. They attach to the muscles of the tongue and replace them. Mexican snapper still works like a normal tongue
Head louse. Fungus lice do not seem to cause any additional harm to the body of the fish. When Bulbul lice replace the tongue, they feed the fish's blood on the one hand, and fish's mucus on the other. This is the only known parasitic way to compley replace the host organism. At present, it is not harmful to human beings to believe that head-on lice are dead.
When larvae enter the mouth of the fish, fish's blood is drawn through the tongue of the fish until the fish's tongue contracts. Then the tail of the fish has been shrinking and connected to replace the fish tongue work from parasitic to crustacean symbiotic.
