Filefish
The filefish (Monacanthidae) are a diverse family of tropical to subtropical tetraodontiform marine fish, which are also known as foolfish, leatherjackets, or shingles. They live in the Atlantic, Pacific, and Indian Oceans. Filefish are closely related to triggerfish, pufferfish, and trunkfish. The filefish family comprises about 102 species in 27 genera. More than half of the species are found in Australian waters, with 58 species in 23 genera. Their laterally compressed bodies and rough, sandpapery skin inspired the filefish's common name. Description Appearing very much like their close relatives the triggerfish, filefish are rhomboid-shaped, with beautifully elaborate cryptic patterns. Deeply keeled bodies give a false impression of size when the fish are viewed facing the flanks. Filefish have soft, simple fins, with comparatively small pectoral fins and truncated, fan-shaped tail fins; a slender, retractable spine crowns the head. Although usually two of these spines oc ...

American Whitespotted Filefish
''Cantherhines macrocerus'', commonly known as the whitespotted filefish, American whitespotted filefish, or whitespotted limefish, is a marine fish found along the coast of Florida extending southward into the Caribbean. This species is distinct and separate from '' Cantherhines dumerilii'', the similarly named whitespotted filefish which is found in the Indian and Pacific oceans. Description The American whitespotted filefish typically has a brown or olive colored body, although it may also be grey. These fish can rapidly change appearance to a high contrast color pattern with a much darker background and many light colored spots With a maximum length of around 18 inches, they are smaller than the scrawled filefish which is also found in their range. The American whitespotted filefish is often seen in pairs. Diet These fish are omnivorous; although they eat animals like sponges, stinging coral and gorgonians, and algae. As aquarium fish The American whitespotted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephanolepis Hispidus
''Stephanolepis hispidus'', the planehead filefish, is a species of bony fish in the family Monacanthidae. Description Planehead filefish grow to a maximum length of , but are more typically about long. Their colour is cryptic, being a more or less mottled pale brown, olive, or green on a light-coloured background, sometimes with darker brown splotches and streaks. The fish are laterally compressed and deep bodied. Their snout is elongated with a terminal mouth. The large yellow eyes are set high on the head and above is a prominent retractable spine. This is the anterior of the two spines associated with the long dorsal fin, which also has 29 to 35 soft rays. The anal fin has no spines and between 30 and 35 soft rays. Theie pectoral fins are small and the tail fin is large and fan-shaped, often with two darker-coloured bands. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetraodontiform
Tetraodontiformes (), also known as the Plectognathi, is an order of ray-finned fishes which includes the pufferfishes and related taxa. This order has been classified as a suborder of the order Perciformes, although recent studies have found that it, as the Tetraodontoidei, is a sister taxon to the anglerfish order Lophiiformes, called Lophiodei, and have placed both taxa within the Acanthuriformes. The Tetraodontiformes are represented by 10 extant families and at around 430 species overall. The majority of the species within this order are marine but a few may be found in freshwater. They are found throughout the world. Taxonomy Tetraodontiformes is a name first used for this order in 1940 by Lev Berg, the order was originally proposed in 1817 as the "''Les Plectognathes''", the Plectognathi. Cuvier divided this into two families ''"Les Gymnodontes"'' and ''"Les Sclerodermes"''. In 1940 Berg first used the term Tetraodontiformes for this order and this name is the currently a ...

Triggerfish
Triggerfish are about 40 species of often brightly colored marine ray-finned fishes belonging to the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the oceanic triggerfish (''Canthidermis maculata''), are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered. Taxonomy The triggerfish family, Balistidae, was first proposed in 1810 by the French polymath Constantine Samuel Rafinesque. The closest relatives to the triggerfishes are the filefishes belonging to the family Monacanthidae and these two families are sometimes classified together in the suborder Balistoidei, for example in the 5th edition of ''Fishes of the World''. Other authorities, however, also include the famili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sargassum
''Sargassum'' is a genus of brown macroalgae ( seaweed) in the order Fucales of the Phaeophyceae class. Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species. Most species within the class Phaeophyceae are predominantly cold-water organisms that benefit from nutrients upwelling, but the genus ''Sargassum'' appears to be an exception. The species within Sargassum are normally benthic, but some of the species may take on a planktonic, often pelagic existence after being removed from reefs during rough weather. Two species (''S. natans'' and ''S. fluitans'') have become holopelagic—reproducing vegetatively and never attaching to the seafloor during their lifecycles. The Atlantic Ocean's Sargasso Sea was named after the algae, as it hosts a large amount of ''Sargassum''. The size of annual blooms in the Atlan ...

Caudal Peduncle
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish (Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish (Chondrichthyes) and jawless fish (Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are predominantl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trunkfish
Ostraciidae or Ostraciontidae is a family of squared, bony fish belonging to the order Tetraodontiformes, closely related to the pufferfishes and filefishes. Fish in the family are known variously as boxfishes, cofferfishes, cowfishes and trunkfishes. It contains about 23 extant species in 6 extant genera. Taxonomy Ostraciidae was first proposed as a family in 1810 by the French polymath Constantine Samuel Rafinesque. In the past this grouping was regarded as a subfamily, the Ostraciinae, along with the subfamily Aracaninae, of a wider Ostraciidae. However, recent phylogenetic studies have concluded that the families Aracanidae and Ostraciidae are valid families but that they are part of the same clade, the suborder Ostracioidei. The 5th edition of ''Fishes of the World'' classifies this clade as the suborder Ostracioidea within the order Tetraodontiformes. Etymology Ostraciidae takes its name from its type genus, ''Ostracion'', a name which means "little box" and is an allusion ...

Invertebrate
Invertebrates are animals that neither develop nor retain a vertebral column (commonly known as a ''spine'' or ''backbone''), which evolved from the notochord. It is a paraphyletic grouping including all animals excluding the chordata, chordate subphylum Vertebrata, i.e. vertebrates. Well-known Phylum, phyla of invertebrates include arthropods, molluscs, annelids, echinoderms, flatworms, cnidarians, and sponges. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxon, taxa have a greater number and diversity of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 10 Micrometre, μm (0.0004 in) myxozoans to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are actually sister chordate subphyla to Vertebrata, being more closely related to vertebrates than to other invertebrates. This makes the "invertebrates" para ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benthic
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from the Ancient Greek word (), meaning "the depths". Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here, known as bottom dwellers, generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the ...

Alga
Algae ( , ; : alga ) is an informal term for any organisms of a large and diverse group of photosynthetic organisms that are not plants, and includes species from multiple distinct clades. Such organisms range from unicellular microalgae, such as cyanobacteria, '' Chlorella'', and diatoms, to multicellular macroalgae such as kelp or brown algae which may grow up to in length. Most algae are aquatic organisms and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds. In contrast, the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. Algae that are carried passively by water are plankton, specifically phytoplankton. Algae constitute a polyphyletic group because they do not include a common ancestor, and although eukaryotic algae with chlorophyll-bearing plastids seem ...
