Combtooth Blenny
Combtooth blennies are blenniiformids; percomorph marine fish of the family Blenniidae, part of the order Blenniiformes. They are the largest family of blennies with around 401 known species in 58 genera. Combtooth blennies are found in tropical and subtropical waters in the Atlantic, Pacific and Indian Oceans; some species are also found in brackish and even freshwater environments. Description The body plan of the combtooth blennies is archetypal to all other blennioids; their blunt heads and eyes are large, with large continuous dorsal fins (which may have three to 17 spines). Their bodies are compressed, elongated, and scaleless; their small, slender pelvic fins (which are absent in only two species) are situated before their enlarged pectoral fins, and their tail fins are rounded. As their name would suggest, combtooth blennies are noted for the comb-like teeth lining their jaws. By far the largest species is the eel-like hairtail blenny at 53 cm in length; most ...

Scartella Cristata
The molly miller (''Scartella cristata'') is a species of fish of the family Blenniidae ( combtooth blennies) in the order Perciformes. It can be found in the Atlantic, Mediterranean, and northwest Pacific Oceans. Its color is a mottled tan, white, and black covering the body and fins. The head of this fish is covered with short hair-like appendages and has two very large eyes. This species reaches in total length. Reproduction This blenny is oviparous; its eggs are demersal and adhesive. Habitat The molly miller is a marine tropical fish that lives in rocks or coral reefs 0–10 m below the surface. Coral reefs are perfect places for the fish to hunt and feed on the small crustaceans and algae that make up its omnivorous diet, and give them shelter and places to hide, as well. Phylogeny A 2020 study which analysed the mitochondrial data of the genus '' Scartella'' for the first time showed that ''Scartella cristata'' is a lineage consisting of 5 clades: 2 in Caribbea ...

Plagiotremus Rhinorhynchos (Blue-lined Sabertooth Blenny)
''Plagiotremus rhinorhynchos'', commonly called the bluestriped fangblenny, is a species of combtooth blenny found in coral reefs in the Pacific and Indian ocean. This species reaches a length of SL. It is also known as the ''bluestriped blenny'', ''bluestriped sabretooth blenny'', ''blunt-nose blenny'', ''cleaner mimic'', ''tube-worm blenny'' or the ''two-stripe blenny''. They hide in deserted worm tubes or other small holes. The fangblenny is a specialised mimic of juvenile bluestreak cleaner wrasse. Those fish serve as cleaners to larger host fish, which attend to have ectoparasites removed. The fangblenny does no cleaning, but bites the host fish and leaves. Its opioid-containing venom helps it escape, as it gives a pain-free bite which also dulls the host's reactions. Description From before birth, their eggs are demersal and adhesive and attach to substrates via a filamentous adhesive pad or pedestal. The bluestriped fangblenny can attain around 90mm in length.

Petroscirtes
''Petroscirtes'' is a genus of combtooth blennies found in the western Pacific, and Indian oceans. Some species of this genus have venom that interacts with opioid receptors. Adults usually inhabit coastal reefs and estuaries to depths of about 10 meters, but they can also be found up to 15 meters in depth in sandy and weedy areas among clumps of Sargassum or other seaweeds in coastal and lagoon reefs. They can be found in nests inside small-necked bottles and abandoned worm tubes or shells. Species There are currently 11 recognized species in this genus: * '' Petroscirtes ancylodon'' Rüppell, 1835 (Arabian fangblenny) * '' Petroscirtes breviceps'' (Valenciennes, 1836) (Striped poison-fang blenny mimic) * '' Petroscirtes fallax'' Smith-Vaniz, 1976 (Deceiver fangbelly) * '' Petroscirtes lupus'' (De Vis, 1885) (Wolf fangbelly) * '' Petroscirtes marginatus'' Smith-Vaniz, 1976 * '' Petroscirtes mitratus'' Rüppell, 1830 (Floral blenny) * ''Petroscirtes pylei'' Smith-Vaniz, 2005 ...

Meiacanthus
''Meiacanthus'' is a genus of combtooth blennies found in the western Pacific and Indian oceans. Many species in this genus make their way into the aquarium trade and several are venomous. The genus name ''Meiacanthus'' is derived from the Greek ''meion'' meaning "less" and ''akantha'' meaning "thorn" and refers to most species having relatively few dorsal fin spines. Species There are currently 28 recognized species in this genus: * '' Meiacanthus abditus'' Smith-Vaniz, 1987 * '' Meiacanthus abruptus'' Smith-Vaniz & G. R. Allen, 2011 * '' Meiacanthus anema'' ( Bleeker, 1852) (Threadless blenny) * '' Meiacanthus atrodorsalis'' ( Günther, 1877) (Forktail blenny) * '' Meiacanthus bundoon'' Smith-Vaniz, 1976 (Bundoon blenny) * '' Meiacanthus crinitus'' Smith-Vaniz, 1987 * '' Meiacanthus cyanopterus'' Smith-Vaniz & G.

Sabre-toothed Blenny
The false cleanerfish (''Aspidontus taeniatus'') is a species of combtooth blenny, a mimic that copies both the dance and appearance of '' Labroides dimidiatus'' (the bluestreak cleaner wrasse), a similarly colored species of cleaner wrasse. It likely mimics that species to avoid predation, as well to occasionally bite the fins of its victims rather than consume parasites. Most veiled attacks occur on juvenile fish, as adults that have been attacked in the past may avoid or even attack ''A. taeniatus.'' It is indigenous to coral reef habitats in the Indo-Pacific. Mimicry Appearance The false cleanerfish primarily lives in coral reef margins among the cleaning stations of the bluestreak cleaner wrasse (''Labroides dimidiatus''), and are usually seen near locations of one or more ''L. dimidiatus.'' With its territory primarily overlapping with its model fish, the false cleanerfish mimics both the appearance and occasionally the behavior of said fish. Though ''A. taeniatus'' is ...

Plankton
Plankton are the diverse collection of organisms found in water (or air) that are unable to propel themselves against a current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales. Marine plankton include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton are similar to marine plankton, but are found in the freshwaters of lakes and rivers. Plankton are usually thought of as inhabiting water, but there are also airborne versions, the aeroplankton, that live part of their lives drifting in the atmosphere. These include plant spores, pollen and wind-scattered seeds, as well as microorganisms swept into the air from terrestrial dust storms and oceanic plankton swept into the air by sea spray. Though many plankton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alga
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) 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, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around their r ...

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'', wh ...

Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...

Animal Shell
An exoskeleton (from Greek ''éxō'' "outer" and ''skeletós'' "skeleton") is an external skeleton that supports and protects an animal's body, in contrast to an internal skeleton (endoskeleton) in for example, a human. In usage, some of the larger kinds of exoskeletons are known as " shells". Examples of exoskeletons within animals include the arthropod exoskeleton shared by chelicerates, myriapods, crustaceans, and insects, as well as the shell of certain sponges and the mollusc shell shared by snails, clams, tusk shells, chitons and nautilus. Some animals, such as the turtle, have both an endoskeleton and an exoskeleton. Role Exoskeletons contain rigid and resistant components that fulfill a set of functional roles in many animals including protection, excretion, sensing, support, feeding and acting as a barrier against desiccation in terrestrial organisms. Exoskeletons have a role in defense from pests and predators, support and in providing an attachment framework fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
