Cyanea citrea Kishinouye, 1910 | |
Cyanea citrea is a species of true jellyfish in the family Cyaneidae. [1] It has been found in waters off the coasts of Japan and Russia. [2] The generic name, Cyanea, is derived from the Latin cyaneus, meaning "deep or dark blue in color". The specific epithet, citrea, is derived from the Latin citreus, meaning "citrus", likely in reference to the species' orange color.
The bell of Cyanea citrea is flat and disc-shaped, and thickens in its center. The bell is about 30 centimetres (12 in) in diameter, and is a deep orange color. The margin of the bell is made up of 32 rounded lobes. Its oral arms are narrow at their tips, but thicken towards the middle before narrowing out once again as they approach the body. The oral arms are a light orange-brown color. The species' tentacles are grouped in eight U-shaped tracts, and are a reddish color at parts distanced from the body. Male genital glands are a light orange-yellow color, while those of females are a dark yellow-brown. [2]
Stomiiformes is an order of deep-sea ray-finned fishes of very diverse morphology. It includes, for example, dragonfishes, lightfishes, loosejaws, marine hatchetfishes and viperfishes. The order contains 4 families with more than 50 genera and at least 410 species. As usual for deep-sea fishes, there are few common names for species of the order, but the Stomiiformes as a whole are often called dragonfishes and allies or simply stomiiforms.
A color term is a word or phrase that refers to a specific color. The color term may refer to human perception of that color which is usually defined according to the Munsell color system, or to an underlying physical property. There are also numerical systems of color specification, referred to as color spaces.
In many languages, the colors described in English as "blue" and "green" are colexified, i.e., expressed using a single umbrella term. To render this ambiguous notion in English, linguists use the blend word grue, from green and blue, a term coined by the philosopher Nelson Goodman – with a rather different meaning – in his 1955 Fact, Fiction, and Forecast to illustrate his "new riddle of induction".
Idioteuthis cordiformis is a species of whip-lash squid found in tropical regions of the west Pacific Ocean. The species is commonly known as the 'love-heart squid' because the species name cordiformis is Latin for 'heart shaped'. Recently, this species has been found to consume small birdbeak dogfish.
The speckled swellshark is a little-known species of catshark, and part of the family Scyliorhinidae, endemic to the waters off northwestern Australia. It occurs on the outer continental shelf and upper continental slope, at a depth of 150–455 m (492–1,493 ft). This species grows to 69 cm (27 in) long and has a stocky body and a short, broad, flattened head. As its common name suggests, its color pattern consists of many dark spots and white-spotted dark saddles and blotches on a light gray background. The juveniles are yellow with dark spots and lines, and a distinctive eyespot-like mark behind each eye. Like other swellsharks, this species can inflate itself as a defensive measure.
Chrysaora hysoscella, the compass jellyfish, is a common species of jellyfish that inhabits coastal waters in temperate regions of the northeastern Atlantic Ocean, including the North Sea and Mediterranean Sea. In the past it was also recorded in the southeastern Atlantic, including South Africa, but this was caused by confusion with close relatives; C. africana, C. fulgida and an undescribed species tentatively referred to as "C. agulhensis".
The Pacific sea nettle, or West Coast sea nettle, is a widespread planktonic scyphozoan cnidarian—or medusa, “jellyfish” or “jelly”—that lives in the northeastern Pacific Ocean, in temperate to cooler waters off of British Columbia and the West Coast of the United States, ranging south to México. The Pacific sea nettle earned its common name in-reference to its defensive, ‘nettle’-like sting; much like the stinging nettle plant, the sea nettle’s defensive sting is often irritating to humans, though rarely dangerous.
Eulithis populata, the northern spinach, is a moth of the genus Eulithis in the family Geometridae.
The Australian reticulate swellshark is a little-known species of catshark in the family Scyliorhinidae. It is found off the coast of northwestern Australia at depths of 290–420 m (950–1,380 ft). This shark has a stocky body and a short, wide head with a capacious mouth. It is characterized by a striking dorsal color pattern of dark brown lines that trace a series of hollow saddles and narrow rings, on a light background. Like other swellsharks, this species can inflate itself when threatened. Its reproduction is oviparous.
Mycena fuscoaurantiaca is a species of mushroom in the family Mycenaceae. First reported as a new species in 2007, the diminutive mushroom is only found in Kanagawa, Japan, where it grows on dead fallen twigs in lowland forests dominated by hornbeam (Carpinus) and Chinese evergreen oak trees. The mushroom has a brownish-orange conical cap that has grooves extending to the center, and reaches up to 11 mm (0.43 in) in diameter. Its slender stem is colored similarly to the cap, and long—up to 60 mm (2.4 in) tall. Microscopic characteristics include the weakly amyloid spores, the smooth, swollen cheilocystidia and pleurocystidia with long rounded tips, the diverticulate hyphae of the cap cuticle, and the absence of clamp connections.
Mycena aurantiomarginata, commonly known as the golden-edge bonnet, is a species of agaric fungus in the family Mycenaceae. First formally described in 1803, it was given its current name in 1872. Widely distributed, it is common in Europe and North America, and has also been collected in North Africa, Central America, and Japan. The fungus is saprobic, and produces fruit bodies (mushrooms) that grow on the floor of coniferous forests. The mushrooms have a bell-shaped to conical cap up to 2 cm in diameter, set atop a slender stipe up to 6 cm long with yellow to orange hairs at the base. The fungus is named after its characteristic bright orange gill edges. A microscopic characteristic is the club-shaped cystidia that are covered with numerous spiky projections, resembling a mace. The edibility of the mushroom has not been determined. M. aurantiomarginata can be distinguished from similar Mycena species by differences in size, color, and substrate. A 2010 publication reported the discovery and characterization of a novel pigment named mycenaaurin A, isolated from the mushroom. The pigment is responsible for its color, and it has antibiotic activity that may function to prevent certain bacteria from growing on the mushroom.
Boletus rubroflammeus is a species of bolete fungus in the family Boletaceae. First described from Michigan in 1971, it is found in the eastern United States and Mexico, where it grows in a mycorrhizal association with hardwood trees. The fruit bodies (mushrooms) of the fungus have caps that are deep red to purplish red, and dark red pores. The stem has coarse, dark red reticulations and a narrow yellow area at the top. All parts of the mushroom quickly stain blue when injured or cut. Lookalikes include Boletus flammans, a lighter-colored species that grows with conifers. Other similar species can be distinguished by differences in distribution, morphology, staining reaction, and microscopic characteristics. Boletus rubroflammeus mushrooms are poisonous, and can cause gastrointestinal distress if consumed.
Boletus subvelutipes, commonly known as the red-mouth bolete, is a bolete fungus in the family Boletaceae. It is found in Asia and North America, where it fruits on the ground in a mycorrhizal association with both deciduous and coniferous trees. Its fruit bodies (mushrooms) have a brown to reddish-brown cap, bright yellow cap flesh, and a stem covered by furfuraceous to punctate ornamentation and dark red hairs at the base. Its flesh instantly stains blue when cut, but slowly fades to white. The fruit bodies are poisonous, and produce symptoms of gastrointestinal distress if consumed.
Cyanea nozakii or Cyanea nozaki (misspelling), commonly known as the ghost jellyfish, is a species of jellyfish found in the northern Pacific Ocean near the coasts of China and Japan. Along with other species of large jellyfish, it is showing a greater tendency to appear in large numbers and cause blooms.
Amanita flavorubens, also known as the yellow American blusher or the yellow American blushing amanita, is a species of the genus Amanita.
Dendrocoelopsis piriformis is a species of freshwater triclad in the family Dendrocoelidae. It is found in Alaska.
Aurelia limbata, the brown-banded moon jelly, is a type of moon jelly that occurs in various places throughout the Pacific Ocean.
Cassiopea ndrosia is a species of true jellyfish in the family Cassiopeidae. It has been found in the Pacific Ocean and in waters surrounding Australia and Fiji.
Cyanea barkeri is a species of true jellyfish in the family Cyaneidae. It has been found in waters off the coast of Australia.
Cyanea purpurea is a species of true jellyfish in the family Cyaneidae. It has been found off the coasts of Sakhalin and China. The generic name, Cyanea, is derived from the Latin cyaneus, meaning "deep or dark blue in color". The specific epithet, purpurea, is derived from the Latin purpureus, meaning "purple", in reference to its violet color.
