Due to Hawaii's isolation 30% of the fish are endemic (unique to the island chain). [ 1 ] The Hawaiian Islands comprise 137 islands and atolls, with a land area of 6,423.4 square miles (16,636.5 km 2 ). [ 2 ]
The great majority of bony fish species have five pairs of gills, although a few have lost some over the course of evolution. The operculum can be important in adjusting the pressure of water inside of the pharynx to allow proper ventilation of the gills, so that bony fish do not have to rely on ram ventilation (and hence near constant motion ...
Five of the seven native freshwater fish species on Hawaii are gobioid. [6] Three of these gobioids, S. stimpsoni (this article), Awaous stamineus (endemic) and Lentipes concolor (endemic) are amphidromous stream dwellers, which are adapted to the steep torrents of Hawaii's mountains (Eleotris sandwicensis and Stenogobius hawaiiensis, both endemic, are unable to pass steep torrents). [7]
The number of gill rakers on the first gill arch can also be used to identify a fish species. Rakers are counted for the upper and lower limbs of the gill arch, and a raker at the joint of the upper and lower limbs is counted as of the lower. Counts for the upper and lower limbs are separated by a + sign and ranges are bracketed, e.g., GR: 3 ...
The genus name Graulia is a reference to Graoully, a mythical dragon from the folklore of Lorraine, France, where the specimens were found.The species name branchiodonta, comes from the Greek words βράγχια "gills" and ὀδούς, ὀδόντος "tooth", the latter which refers to the large teeth of the ceratobranchials.
This fish won’t take first prize at a beauty pageant any time soon, but at 28 grams of protein and 134 calories per four ounce serving, it’s a nutritional winner. Try it pan-seared with ...
Because the best-known species are adapted to attack the gill filaments of the fishes, Ergasilidae are known by common names such as gill lice. However, some species have been found infesting, and presumably causing, external skin lesions of fish. Immature instars and mature males of Ergasilidae are fairly typical free-living planktonic copepods.
Mussels that produce conglutinates and super-conglutinates are often gill parasites, the glochidia attaching to the fish gills to continue their development into juveniles. [10] A cyst is quickly formed around the glochidia, and they stay on the fish for several weeks or months before they fall off as juvenile freshwater mussels which then bury ...
