Cymothoa exigua, or the tongue-eating louse, is a parasitic isopod of the family Cymothoidae.It enters a fish through the gills.The female attaches to the tongue, while the male attaches to the gill arches beneath and behind the female.
Giant isopods are a good example of deep-sea gigantism (cf. giant squid), as they are far larger than the "typical" isopods that are up to 5 cm (2.0 in). Bathynomus can be divided into "giant" species where the adults generally are between 8 and 15 cm (3.1 and 5.9 in) long and "supergiant" species where the adults are typically between 17 and ...
The largest isopod is in the genus Bathynomus and some large species are fished commercially for human food in Mexico, Japan and Hawaii. [15] Some isopod groups have evolved a parasitic lifestyle, particularly as external parasites of fish. [9] They can damage or kill their hosts and can cause significant economic loss to commercial fisheries. [16]
Notable organisms that exhibit deep-sea gigantism include the big red jellyfish, [5] Stygiomedusa jellyfish, the giant isopod, [4] giant ostracod, [4] the giant sea spider, [4] the giant amphipod, the Japanese spider crab, the giant oarfish, the deepwater stingray, the seven-arm octopus, [6] and a number of squid species: the colossal squid (up ...
Unlike a goldfish in is fish bowl, the ones found in the wild are free to eat as much and anytime they want. Gabriel said in massive bodies of water like Lake Erie this means an endless supply of ...
It is a member of the giant isopods (Bathynomus), and as such it is related—albeit distantly—to shrimps and crabs. [2] It was the first Bathynomus species ever documented and was described in 1879 by French zoologist Alphonse Milne Edwards after the isopod was found in fishermen's nets off the coast of the Dry Tortugas in the Gulf of Mexico .
It’s no fish tale. Giant goldfish have been appearing in freshwater lakes around the country. It’s a development that has surprised people. “Honestly, I was in shock. I almost fell off my ...
The Cymothoidae are a family of isopods in the suborder Cymothoida found in both marine and freshwater environments. Cymoithoids are ectoparasites, usually of fish, and they include the bizarre "tongue-biter" (Cymothoa exigua), which attaches to a fish's tongue, causing it to atrophy, and replaces the tongue with its own body.
