Chelmonops Curiosus
''Chelmonops curiosus'', truncate coralfish, truncate butterflyfish, western talma or squareback butterflyfish, is a species of marine ray-finned fish, a butterflyfish from the family Chaetodontidae. It is endemic to Australia. Description ''Chelmonops curiosus'' has a very deep strongly compressed body, which is more than half its standard length. It has a small head with a long, tapered snout and a tiny mouth at the end of its snout. There is a single, elongated dorsal fin with the separation between the spiny portion and the soft-rayed portion being hardly visible. The first spine is very small but as they progress towards the posterior they become longer and longer. In juveniles the soft part of the dorsal fin is rounded but it is pointed in adults and has a triangular profile when raised. The anal fin is smaller than the dorsal fin. The caudal fin is truncate. The background colour of this fish is steel grey with amounts of black shading different for each individual. They a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pelvic Fin
Pelvic fins or ventral fins are paired fins located on the ventral surface of fish. The paired pelvic fins are homologous to the hindlimbs of tetrapods. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays ( lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into a spiny copulatory device that grasps the female during mating.

Chelmonops
''Chelmonops'' is a small genus of ray-finned fish, butterflyfishes from the family Chaetodontidae. Unlike the mainly tropical distribution of most marine butterflyfishes, ''Chelmonops'' is restricted to temperate and subtropical coastal waters along the southern half of Australia. The name of the genus is a compound of the genus name ''Chelmon'' coined by Georges Cuvier Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier ... for the genus that ''C. truncatus'' was originally placed in, and the word ''ops'' which means “resembles”. Species There are currently two recognized species in this genus: * '' Chelmonops curiosus'' Kuiter, 1986 (Western talma) * '' Chelmonops truncatus'' ( Kner, 1859) (Eastern talma) References Marine fish genera Taxa named by Pieter Bleeker ...

Territoriality
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the indivi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omnivory
An omnivore () is an animal that has the ability to eat and survive on both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet. Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms (Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears. The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. Frugivores in ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616.

Shark Bay
Shark Bay ( Malgana: ''Gathaagudu'', "two waters") is a World Heritage Site in the Gascoyne region of Western Australia. The http://www.environment.gov.au/heritage/places/world/shark-bay area is located approximately north of Perth, on the westernmost point of the Australian continent. UNESCO's official listing of Shark Bay as a World Heritage Site reads: : History The record of Australian Aboriginal occupation of Shark Bay extends to years BP. At that time most of the area was dry land, rising sea levels flooding Shark Bay between BP and BP. A considerable number of aboriginal midden sites have been found, especially on Peron Peninsula and Dirk Hartog Island which provide evidence of some of the foods gathered from the waters and nearby land areas. An expedition led by Dirk Hartog happened upon the area in 1616, becoming the second group of Europeans known to have visited Australia. (The crew of the '' Duyfken'', under Willem Janszoon, had visited Cape York in 1606 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victor Harbor, South Australia
Victor Harbor is a town in the Australian state of South Australia located within the City of Victor Harbor on the south coast of the Fleurieu Peninsula, about south of the state capital of Adelaide. The town is the largest population centre on the peninsula, with an economy based upon agriculture, fisheries and various industries. It is also a highly popular tourist destination, with the area's population greatly expanded during the summer holidays, usually by Adelaide locals looking to escape the summer heat. It is a popular destination with South Australian high school graduates for their end of year celebrations, known colloquially as schoolies. History Victor Harbor lies in the traditional lands of the Ramindjeri clan of the Ngarrindjeri people. Matthew Flinders in visited the bay on 8 April 1802 while on the first circumnavigation of the continent, mapping the unsurveyed southern Australian coast from the west. He encountered Nicolas Baudin in '' Le Geographe'' ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocellus
A simple eye (sometimes called a pigment pit) refers to a form of eye or an optical arrangement composed of a single lens and without an elaborate retina such as occurs in most vertebrates. In this sense "simple eye" is distinct from a multi-lensed "compound eye", and is not necessarily at all simple in the usual sense of the word. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive. Arthropods differ widely in the habitats in which they live, as well as their visual requirements for finding food or conspecifics, and avoiding predators. Consequently, an enormous variety of eye types are found in arthropods. They possess a wide variety of novel solutions to overcome visual problems or limitations. Use of the term ''simple eye'' is flexible, and must be interpreted in proper context; for example, the eyes of humans and of other large animals such as most cephalopods, are '' camera eyes'' and i ...

Caudal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from '' Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actino ...
