Labrid
The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 81 genera, which are divided into 9 subgroups or tribes. They are typically small, most of them less than long, although the largest, the humphead wrasse, can measure up to . They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera '' Bodianus'', '' Epibulus'', ''Cirrhilabrus'', '' Oxycheilinus'', and ''Paracheilinus'' hide among the tentacles of the free-living mushroom corals & '' Heliofungia actiniformis''. The word "wrasse" comes from the Cornish word ''wragh'', a lenited form of ''gwragh'', meaning an old woman or hag, via Cornish dialect ''wrath''. It is related to the Welsh ''gwrach'' and Breton ''gwrac'h''. Distribution Most wrasses inhabit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sex Change In Animals
Sequential hermaphroditism (called dichogamy in botany) is a type of hermaphroditism that occurs in many fish, gastropods, and plants. Sequential hermaphroditism occurs when the individual changes its sex at some point in its life. In particular, a sequential hermaphrodite produces eggs (female gametes) and sperm (male gametes) at different stages in life. Species that can undergo these changes from one sex to another do so as a normal event within their reproductive cycle that is usually cued by either social structure or the achievement of a certain age or size. In animals, the different types of change are male to female (protandry or protandrous hermaphroditism), female to male (protogyny or protogynous hermaphroditism), bidirectional (serial or bidirectional hermaphroditism). Both protogynous and protandrous hermaphroditism allow the organism to switch between functional male and functional female. Bidirectional hermaphrodites have the capacity for sex change in either direc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Humphead Wrasse
The humphead wrasse (''Cheilinus undulatus'') is a large species of wrasse mainly found on coral reefs in the Indo-Pacific region. It is also known as the Māori wrasse, Napoleon wrasse, Napoleon fish, Napoleonfish, ''so mei'' 蘇眉 (Cantonese), ''mameng'' (Filipino), and ''merer'' in the Pohnpeian language of the Caroline Islands. Description The humphead wrasse is the largest living member of the family Labridae. Males, typically larger than females, are capable of reaching up to 2 meters and weighing up to 180 kg, but the average length is a little less than 1 meter. Females rarely grow larger than one meter. This species can be easily identified by its large size, thick lips, two black lines behind its eyes, and the hump on the foreheads of larger adults. Its color can vary between dull blue-green to more vibrant shades of green and purplish-blue. Adults are usually observed living singly, but are also seen in male/female pairs and in small groups.

Fish Jaw
Most bony fishes have two sets of jaws made mainly of bone. The primary oral jaws open and close the mouth, and a second set of pharyngeal jaws are positioned at the back of the throat. The oral jaws are used to capture and manipulate prey by biting and crushing. The pharyngeal jaws, so-called because they are positioned within the pharynx, are used to further process the food and move it from the mouth to the stomach. Cartilaginous fishes, such as sharks and rays, have one set of oral jaws made mainly of cartilage. They do not have pharyngeal jaws. Generally jaws are articulated and oppose vertically, comprising an upper jaw and a lower jaw and can bear numerous ordered teeth. Cartilaginous fishes grow multiple sets ''(polyphyodont)'' and replace teeth as they wear by moving new teeth laterally from the medial jaw surface in a conveyor-belt fashion. Teeth are replaced multiple times also in most bony fishes, but unlike cartilaginous fishes, the new tooth erupts only af ...

Mushroom Coral
The Fungiidae () are a family of Cnidaria, commonly known as mushroom corals or plate corals. The family contains thirteen extant genera. They range from solitary corals to colonial species. Some genera such as ''Cycloseris'' and ''Fungia'' are solitary organisms, ''Polyphyllia'' consists of a single organism with multiple mouths, and ''Ctenactis'' and ''Herpolitha'' might be considered as solitary organisms with multiple mouths or a colony of individuals, each with its separate mouth. Characteristics Species are generally solitary marine animals capable of benthic locomotion. These corals often appear to be bleached or dead. In most genera, a single polyp emerges from the center of the skeleton to feed at night. Most species remain fully detached from the substrate in adulthood. Some are immobile as well as colonial. Ecology Some species of mushroom coral such as '' Fungia repanda'' and ''Ctenactis echinata'' are able to change sex. This is posited to take place in response ...

Heliofungia Actiniformis
''Heliofungia actiniformis'' is a solitary species of mushroom coral, a large polyp stony coral in the family Fungiidae. This coral is found in shallow water in the Indo-Pacific region. It is a zooxanthellate species. It is a popular coral in the reef aquarium trade; wild populations are threatened by disease, climate change, and over-collecting, and the species is considered vulnerable by the IUCN. Description Although fixed to the substrate as a juvenile, this coral becomes detached later and is free-living as an adult. It is circular or oval with a diameter of up to and height of . The corallum (stony skeleton) is thick and solid. The septa (stony ridges) are in several orders. The early order septa are larger than later order ones and have more prominent, lobe-like or triangular teeth. All the septa are granulate, and continue to the underside of the corallum as fine ridges known as costae. There is an attachment scar in the centre of the underside. The polyp is thick and f ...

Moon Wrasse
The moon wrasse (''Thalassoma lunare'') also known as the crescent wrasse or lyretail wrasse, is a species of wrasse native to the Indian Ocean and the western Pacific Ocean. It is an inhabitant of coral reefs and surrounding areas at depths from . Moon wrasses are carnivorous and tend to prey on fish eggs and small sea-floor dwelling invertebrates. This species can reach in total length. It is of minor importance to local commercial fisheries and can also be found in the aquarium trade. The juvenile is blue on the lower half of its body, with a black spot in the middle of the dorsal fin and a black blotch on the caudal fin base. As it matures, the spot turns into a yellow crescent, hence the name. The body is green, with prominently marked scales. Coloration of the head ranges from blue to magenta, with a broken checkerboard pattern. Moon wrasses are active fish, said to be moving all day long. They are also territorial, nipping, chasing, and otherwise harassing fish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballan Wrasse
The ballan wrasse (''Labrus bergylta'') is a species of marine ray finned fish from the family Labridae, the wrasses. It is found in the eastern Atlantic Ocean, where it inhabits rocky areas. Like many wrasse species, it is a protogynous hermaphrodite—all fish start life as females, and some dominant fish later become males. It is used as a food fish in some areas and it is also finding use as a cleaner fish in the aquaculture of Atlantic salmon (''Salmo salar'') in northwestern Europe. Description The ballan wrasse is a large, heavy bodied wrasse with a relatively deep body and large head. It has a smallish mouth which is surrounded by thick, fleshy, rather wrinkled lips, and the jaws are armed with a single row of robust teeth which are sharp and pointed in young fish but blunter and more worn in older fish. It has a long dorsal fin which has 18–21 spines in its anterior portion and 9–13 branched rays in the rear part. The anal fin is markedly shorter and has three spines ...
