Ranitomeya Aquamarina
''Ranitomeya aquamarina'', also known as the metallic poison frog, is a species of small frogs in the family Dendrobatidae endemic to the Juruá River basin of Brazil. It is one of at least 18 species named in the genus ''Ranitomeya'' and is uniquely characterized by its bright blue to yellow-green and black body and metallic spotted legs. Discovery A series of four Rapid Assessment Program for Environmental and Long-Term Ecological Research (RAPELD) modules were recently established in the Juruá River basin of Brazil, a region of the Amazon rainforest that is poorly studied and difficult to access. After monitoring these modules through 2023 and 2024, researchers identified an unusual frog in the genus ''Ranitomeya''. It was only observed in one of the four RAPELD sites—near the Eiru River, a tributary of the Juruá River—in Eirunepé of Amazonas (Brazilian state), Amazonas, Brazil. 13 adult individuals—eight males and five females—were collected from this site for fur ...

Vocal Sac
The vocal sac is the flexible Biological membrane, membrane of skin possessed by most male frogs and toads. The purpose of the vocal sac is usually as an amplification of their mating or advertisement call. The presence or development of the vocal sac is one way of externally determining the sex of a frog or toad in many species; taking frogs as an example; The vocal sac is open to the mouth cavity of the frog, with two slits on either side of the tongue. To call, the frog inflates its lungs and shuts its nose and mouth. Air is then expelled from the lungs, through the larynx, and into the vocal sac. The vibrations of the larynx emits a sound, which resonance, resonates on the elastic membrane of the vocal sac. The resonance causes the sound to be amplified and allows the call to carry further. Muscles within the body wall force the air back and forth between the lungs and vocal sac. Development The development of the vocal sac is different in most species, however they mostly fo ...

Turquoise
Turquoise is an opaque, blue-to-green mineral that is a hydrous phosphate of copper and aluminium, with the chemical formula . It is rare and valuable in finer grades and has been prized as a gemstone for millennia due to its hue. The robin egg blue or sky blue color of the Persian turquoise mined near the modern city of Nishapur, Iran, has been used as a guiding reference for evaluating turquoise quality. Like most other opaque gems, turquoise has been devalued by the introduction of treatments, imitations, and synthetics into the market. Names The word ''turquoise'' dates to the 17th century and is derived from the Old French ''turquois'' meaning "Turkish" because the mineral was first brought to Europe through the Ottoman Empire.Turquoise

Yellow-green
Chartreuse (, , ), also known as yellow-green or greenish yellow, is a color between yellow and green.

Shades Of Black
Shades of black, or off-black colors, are colors that differ only slightly from pure black. These colors have a low lightness. From a photometric point of view, a color which differs slightly from black always has low relative luminance. Colors often considered "shades of black" include onyx, black olive, charcoal, and jet. These colors may be considered for part of a neutral color scheme, usually in interior design as a part of a background for brighter colors. Black and dark gray colors are powerful accent colors that suggest weight, dignity, formality, and solemnity. In color theory, a ''shade'' is a pure color mixed with black. It decreases its lightness while nearly conserving its chromaticity. Strictly speaking, a "shade of black" is always a pure black itself and a "tint of black" would be a neutral gray. In practice, many off-black colors possess a hue and a colorfulness (also called saturation). Black Black is a color, the perception of which is evoked by the tota ...

Aquamarine (gem)
Aquamarine is a pale-blue to light-green variety of the beryl family, with its name relating to water and sea. The color of aquamarine can be changed by heat, with a goal to enhance its physical appearance (though this practice is frowned upon by collectors and jewelers). It is the birth stone of March. Aquamarine is a fairly common gemstone, rendering it more accessible for purchase, compared to other gems in the beryl family. Overall, its value is determined by weight, color, cut, and clarity. It is transparent to translucent and possesses a hexagonal crystal system. Aquamarine mainly forms in granite pegmatites and hydrothermal veins, and it is a very lengthy process that can take millions of years to form. Aquamarine occurs in many countries over the world, and is most commonly used for jewelry, decoration and its properties. Aquamarine is mainly extracted through open-pit mining, however underground mining is also a possibility to access aquamarine reserves. Aquamarine i ...
