Gerres cinereus (Walbaum, 1792) | |
Gerres cinereus, also known by its common name yellowfin mojarra is a species from the genus Gerres . [1] The species was originally described by Johann Julius Walbaum in 1792. [2]
The koala, sometimes called the koala bear, is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae. Its closest living relatives are the wombats. The koala is found in coastal areas of the island's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, dark nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (8.8–33.1 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations possibly are separate subspecies, but this is disputed.
The American paddlefish, also known as a Mississippi paddlefish, spoon-billed cat, or spoonbill, is a species of ray-finned fish. It is the last living species of paddlefish (Polyodontidae). This family is most closely related to the sturgeons; together they make up the order Acipenseriformes, which are one of the most primitive living groups of ray-finned fish. Fossil records of other paddlefish species date back 125 million years to the Early Cretaceous, with records of Polyodon extending back 65 million years to the early Paleocene. The American paddlefish is a smooth-skinned freshwater fish with an almost entirely cartilaginous skeleton and a paddle-shaped rostrum (snout), which extends nearly one-third its body length. It has been referred to as a freshwater shark because of its heterocercal tail or caudal fin resembling that of sharks, though it is not closely related. The American paddlefish is a highly derived fish because it has evolved specialised adaptations such as filter feeding. Its rostrum and cranium are covered with tens of thousands of sensory receptors for locating swarms of zooplankton, its primary food source. The only other species of paddlefish that survived to modern times was the Chinese paddlefish, last sighted in 2003 in the Yangtze River in China and considered to have gone extinct no later than 2010.
The Dolly Varden trout is a species of salmonid ray-finned fish native to cold-water tributaries of the Pacific Ocean in Asia and North America. Despite the name "trout", it belongs to the genus Salvelinus (chars), which includes 51 recognized species, the most prominent being the brook, lake and bull trout as well as the Arctic char. Although many populations are semi-anadromous, riverine and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the Salvelinus alpinus complex, as many populations of bull trout, Dolly Varden trout and Arctic char overlap.
Salvelinus is a genus of salmonid fish often called char or charr; some species are called "trout". Salvelinus is a member of the subfamily Salmoninae within the family Salmonidae. The genus has a northern circumpolar distribution, and most of its members are typically cold-water fish that primarily inhabit fresh waters. Many species also migrate to the sea.
Zu cristatus, the scalloped ribbonfish, is a ribbonfish of the family Trachipteridae found circumglobally in all oceans at tropical latitudes, at depths down to 90 m. Its length is up to 118 cm.
Conus cinereus, common name the sunburnt cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies.
Andamia is a genus of combtooth blennies found in the Pacific and Indian Oceans.
Eleginus is a genus of cods. There are two recognized species:
Microgadus, the tomcods, is a genus of cods.
Urophycis is a genus of phycid hakes.
Strongylura is a genus of needlefishes from the family Belonidae which is distributed throughout the tropical and warmer temperate waters of the world, including some species which live in freshwater.
Scomberesox is a genus of sauries. It is one of two in the family Scomberesocidae. The generic name Scomberesox is a compound of scomber and the Latin esox meaning pike.
Holocentrus is a genus of squirrelfishes found in the Atlantic Ocean.
The longfin gurnard, the long-finned gurnard or shining gurnard, is a species of ray-finned fish belonging to the family Triglidae, the gurnards and sea robins. This fish is found in the eastern Atlantic Ocean, including the Mediterranean Sea and the Black Sea. This species is of commercial importance as a food fish.
Gerres is a genus of mojarras found mostly in coastal regions from the eastern Atlantic Ocean through the Indian Ocean to the western Pacific. A single species, G. simillimus, is from the East Pacific. They mainly inhabit salt and brackish waters, but will enter fresh water. At least one species, Gerres cinereus, displays an ability akin to gyroscopic stability, allowing it to remain in a remarkably static spatial position relative to the water flowing around it.
Amblygaster sirm, the spotted sardinella, also known as the northern pilchard, spotted pilchard, spotted sardine, and trenched sardine, is a reef-associated marine species of sardinellas in the herring family Clupeidae.
Chirolophis ascanii, or Yarrell's blenny, is a species of fish belonging to the family Stichaeidae. It is native to Northern European coasts. It was named for the English naturalist William Yarrell.
Lumpenus lampretaeformis, the snakeblenny, is a species of marine ray-finned fish belonging to the family Stichaeidae, the pricklebacks and shannies.
Lumpenus is a genus of marine ray-finned fishes belonging to the family Stichaeidae.
Chirolophis is a genus of marine ray-finned fishes belonging to the family Stichaeidae, the pricklebacks and shannies.
