Sexual dimorphismSex-specific adaptationsMandarin ducks, male (left) and female (right) depicts the male having more color vibrancy compared to his female counterpart, illustrating the dramatic difference in plumage between them, a manifestation of sexual dimorphismSexual dimorphism is the condition where different sexes of the same species exhibit different morphological characteristics, including characteristics not directly involved in reproduction.
PercomorphaPercomorpha (from Latin'perch' and Ancient Greek (morphḗ)'shape, appearance') is an extremely large and diverse clade of ray-finned fish. EvolutionPercomorpha are the most diverse group of teleost fish today. Teleosts, and percomorphs in particular, thrived during the Cenozoicera. Fossil evidence shows that there was a major increase in size and abundance of teleosts immediately after the mass extinction event at the Cretaceous-Paleogene boundaryc. 66 Ma ago.
SpeciesBasic unit of taxonomic classification, below genusThe hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown.A species (pl. species) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity.
DraconettidaeThe Draconettidae, slope dragonets, are a small family (about 12-14 species) of fish in the order Perciformes. They are found in temperate to tropical waters of the Atlantic, Indian and western Pacific Oceans. They are closely related to, and appear similar to, the fish of the Callionymidae. They are small fish, the largest species reaching 12 cm (4.7 in) long. Like the callionymids, they are bottom-dwelling fish, and usually sexually dimorphic.
Indo-PacificThe Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two.
FishA fish is an aquatic, anamniotic, gill-bearing vertebrateanimal with a tough cranium to protect the brain, but lacking limbs with digits. Fish can be grouped into the more basaljawless fish and the more common jawed fish, the latter including all livingcartilaginous and bony fish, as well as the extinct placoderms and acanthodians.
Morphology (biology)In biology, morphology is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function.
Tentacled dragonetThe tentacled dragonet (Anaora tentaculata) is a species of dragonet native to tropical reefs in the western Pacific Ocean.
Greek languageGreek (Modern Greek: ελληνικά, romanized: elliniká; Ancient Greek: ἑλληνική, romanized: hellēnikḗ) is an Indo-European language, constituting an independent Hellenic branch within the Indo-European language family. It is native to the territories that have had populations of Greeks since antiquity: Greece, Cyprus, Egypt, Turkey, Italy (in Calabria and Salento), southern Albania, and other regions of the Balkans, Caucasus, the Black Sea coast, and the .
GobioideiThe Gobioidei are a suborder of percomorph fish. Many of these fishes are called gobies. It is by far the largest and most diverse order within the order Gobiiformes, and one of the most diverse groups of ray-finned fish in general. The suborder, which was previously considered a suborder of Perciformes, is made up of about 2,211 species that are divided between seven families. Phylogenetic relationships of the Gobioidei have been elucidated using molecular data.
Benthic zoneEcological region at the lowest level of a body of waterThe benthic zone, from Ancient Greek βένθος (bénthos) 'the depths of the ocean', is the ecological region at the lowest level of a body of water, such as a stream, river, lake, or ocean, including the sediment surface and some sub-surface layers. Organisms living in this zone are called benthos or, more informally, bottom dwellers.GenusGenus (; pl.: genera) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. E.g. Panthera leo (lion) and Panthera onca (jaguar) are two species within the genus Panthera.*As an Amazon Associate I earn from qualifying purchases.
