Ecsenius Tessera
''Ecsenius tessera'' is a species of combtooth blenny in the genus ''Ecsenius''. It is found in coral reefs in the western Pacific ocean, around Vanuatu. It can reach a maximum length of 4.5 centimetres. Blennies in this species feed primarily off of plants, including benthic algae and weeds. References * Springer, V. G. 1988 (14 Sept.)

Victor Gruschka Springer
Victor Gruschka Springer (June 2, 1928 – September 18, 2022) was an American biologist who was a Senior Scientist emeritus, Division of Fishes at the Smithsonian Institution's National Museum of Natural History. He was a specialist in the anatomy, classification, and distribution of fishes, with a special interest in tropical marine shorefishes. He published numerous scientific studies on these subjects; also, a popular book called "Sharks in Question, the Smithsonian Answer Book" 1989. Education Springer gained his first degree, B.A. in biology at Emory University in 1948. His M.S. in botany at the University of Miami in 1954 was followed by his Ph.D. in zoology at the University of Texas in 1957. Research interests Springer's research interests included the classification, evolution, and biogeography of fishes, especially marine fishes and notably Blennioid fishes. He was also interested in late 19th and 20th Century scientific illustrators of fishes such as Charles B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combtooth Blenny
Combtooth blennies are blenny, blenniiformids; Percomorpha, percomorph marine fish of the family Blenniidae, part of the Order (biology), 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 Ocean, Atlantic, Pacific Ocean, 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 ...

Ecsenius
''Ecsenius'' is a large genus of fish in the family Blenniidae.

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the 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 fish, mollusks, worms, crustaceans, ...

Pacific
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .

Vanuatu
Vanuatu ( or ; ), officially the Republic of Vanuatu (; ), is an island country in Melanesia located in the South Pacific Ocean. The archipelago, which is of volcanic origin, is east of northern Australia, northeast of New Caledonia, east of New Guinea, southeast of Solomon Islands, and west of Fiji. Vanuatu was first inhabited by Melanesians, Melanesian people. The first Europeans to visit the islands were a Spanish expedition led by Portuguese navigator Pedro Fernandes de Queirós, Fernandes de Queirós, who arrived on the largest island, Espíritu Santo, in 1606. Queirós claimed the archipelago for Spain, as part of the colonial Spanish East Indies and named it . In the 1880s, France and the United Kingdom of Great Britain and Ireland, United Kingdom claimed parts of the archipelago, and in 1906, they agreed on a framework for jointly managing the archipelago as the New Hebrides through an Anglo-French condominium (international law), condominium.

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 ...

Algae
Algae ( , ; : alga ) is an informal term for any organisms of a large and diverse group of photosynthesis, 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 embryophyte, land plants. The largest and most complex marine algae are called seaweeds. In contrast, the most complex freshwater forms are the Charophyta, a Division (taxonomy), 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 Polyphyly, polyphyletic group because they do not include a common ancestor, and although Eu ...

Fish Described In 1988
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...
