Abudefduf Saxatilis
The sergeant major or píntano (''Abudefduf saxatilis'') is a species of damselfish. It grows to a maximum length of about . Distribution and habitat ''Abudefduf saxatilis'' is found in the Atlantic Ocean. Populations in the western part of the Atlantic Ocean are found from the north eastern coast of the United States south to the Gulf of Mexico, the Bahamas, islands around the Caribbean Sea, the eastern coast of Central and South America all the way to Uruguay. In the eastern Atlantic Ocean, they are found from Portugal, Azores, the Canary Islands, Cape Verde, and western Africa. Its distribution remains unclear in the Mediterranean Sea due to possible confusion with Abudefduf vaigiensis and Abudefduf troschelii.Atlas of Exotic Fishes in the Mediterranean Sea (Abudefduf saxatilis). 2nd Edition. 2021. 366p. CIESM Publishers, Paris, Monaco.https://ciesm.org/atlas/fishes_2nd_edition/Abudefduf_saxatilis.pdf Juveniles are common in tide pools while adults are found over coral reefs. ...

Florida
Florida is a state located in the Southeastern region of the United States. Florida is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Bahamas and Atlantic Ocean, and to the south by the Straits of Florida and Cuba; it is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. Spanning , Florida ranks 22nd in area among the 50 states, and with a population of over 21 million, it is the third-most populous. The state capital is Tallahassee, and the most populous city is Jacksonville. The Miami metropolitan area, with a population of almost 6.2 million, is the most populous urban area in Florida and the ninth-most populous in the United States; other urban conurbations with over one million people are Tampa Bay, Orlando, and Jacksonville. Various Native American groups have inhabited Florida for at least 14,000 years. In 1513, Spanish explorer Juan Ponce de León became the first k ...

Portugal
Portugal, officially the Portuguese Republic ( pt, República Portuguesa, links=yes ), is a country whose mainland is located on the Iberian Peninsula of Southwestern Europe, and whose territory also includes the Atlantic archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, and its Iberian portion is bordered to the west and south by the Atlantic Ocean and to the north and east by Spain, the sole country to have a land border with Portugal. Its two archipelagos form two autonomous regions with their own regional governments. Lisbon is the capital and largest city by population. Portugal is the oldest continuously existing nation state on the Iberian Peninsula and one of the oldest in Europe, its territory having been continuously settled, invaded and fought over since prehistoric times. It was inhabited by pre-Celtic and Celtic peoples who had contact with Phoenicians and Ancient Greek traders, it was ruled by the Ro ...

Zooplankton
Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word for ''animal''). Plankton are aquatic organisms that are unable to swim effectively against currents, and consequently drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton, which are the plant component of the plankton community ("phyto" comes from the Greek word for ''plant''). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding). This means zooplankton cannot manufacture their own food but must eat other plants or animals instead — in particular they eat phytoplankton. Zooplankton are generally larger than phytoplankton, most are microscopic, but some (such as jellyfish) are macroscopic and can be seen with the naked eye. Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, fo ...

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Sergeant Major Fish Caribe
Sergeant (abbreviated to Sgt. and capitalized when used as a named person's title) is a rank in many uniformed organizations, principally military and policing forces. The alternative spelling, ''serjeant'', is used in The Rifles and other units that draw their heritage from the British light infantry. Its origin is the Latin , 'one who serves', through the French term . The term ''sergeant'' refers to a non-commissioned officer placed above the rank of a corporal, and a police officer immediately below a lieutenant in the US, and below an inspector in the UK. In most armies, the rank of sergeant corresponds to command of a squad (or section). In Commonwealth armies, it is a more senior rank, corresponding roughly to a platoon second-in-command. In the United States Army, sergeant is a more junior rank corresponding to a squad- (12 person) or platoon- (36 person) leader. More senior non-commissioned ranks are often variations on sergeant, for example staff sergeant, gunnery s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Reefs
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of Colony (biology), colonies of coral polyp (zoology), polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the Class (biology), class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fis ...

Tide Pools
A tide pool or rock pool is a shallow pool of seawater that forms on the rocky intertidal shore. Many of these pools exist as separate bodies of water only at low tide. Many tide pool habitats are home to especially adaptable animals that have engaged the attention of naturalists and marine biologists, as well as philosophical essayists: John Steinbeck wrote in ''The Log from the Sea of Cortez'', "It is advisable to look from the tide pool to the stars and then back to the tide pool." Zones from shallow to deep The rocky shoreline exhibits zonation as a feature of the shoreline. Tidal movements of water creates zonation patterns along rocky shores from high to low-tide. The area above the high-tide mark is the supralittoral zone which is virtually a terrestrial environment. The area around the high-tide mark is known as the intertidal fringe. Between the high and low-tide marks is the intertidal or littoral zone. Below the low-tide mark is the sublittoral or subtidal ...

Abudefduf Troschelii
''Abudefduf troschelii'', the Pacific sergeant major or Panama sergeant major, is a species of damselfish belonging to the family Pomacentridae that can be identified by the pronounced black stripes on the lateral sides of the fish.Wibowo, K., Koeda, K., Muto, N. et al. Ichthyol Res (2018) 65: 471. Its specific name honors the zoologist Franz Hermann Troschel (1810-1882). It is native to the neritic pelagic zone of the shallow water coral reefs in the Eastern Pacific Ocean and they are an omnivorous species feeding on plankton and algae attached to their coral habitat. ''Abudefduf troschelii'' is a sister-species of '' A. saxatilis'' but have diverged from each other since the uplift of the isthmus of Panama, separated by the rise of the Panama land bridge 3.1 to 3.5 million years ago. Males, like in many other marine species, take care of and defend newborn ''A. troschelii'' after they have been hatched by eggs from the female. There are currently no major threats to the species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abudefduf Vaigiensis
The Indo-Pacific sergeant (''Abudefduf vaigiensis'') is a species of damselfish in the family Pomacentridae. It may also be known as the Sergeant major although this name is usually reserved for the closely related species ''Abudefduf saxatilis''. The closely related ''Abudefduf caudobimaculatus'' was formerly considered to be synonymous with this species and, according to some authorities, is synonymous. Distribution The Indo-Pacific sergeant is found in the Indo-Pacific including the Red Sea. Indian Ocean populations are found in the Red Sea, the Gulf of Aden, Arabia, the Persian Gulf, the Arabian Sea, the Maldives, eastern Africa, Tanzania, Madagascar, Seychelles, Sri Lanka, the Andaman Sea, Indonesia, Malaysia, and Australia. Populations in the Pacific Ocean are found in the Gulf of Thailand, Malaysia, Indonesia, the Philippines, Taiwan, Japan, the Yellow Sea, the Great Barrier Reef around Australia, New Zealand, and Pacific islands all the way to Hawaii.
