Pinecone fishes are small and unusual marine fish of the family Monocentridae. The family contains just four species in two genera, one of which is monotypic. Their distribution is limited to tropical and subtropical waters of the Indo-Pacific. Pinecone fishes are popular subjects of public aquaria, but are both expensive and considered a ...
Amanita ravenelii, commonly known as the pinecone lepidella, is a species of fungus in the family Amanitaceae. The whitish fruit bodies are medium to large, with caps up to 17 centimetres (6 + 1 ⁄ 2 inches) wide, and stems up to 25 cm (10 in) long. The cap surface has large warts and the stem has a scaly, bulbous base.
Pine oil is an essential oil obtained from a variety of species of pine, particularly Pinus sylvestris.Typically, parts of the trees that are not used for lumber — stumps, etc. — are ground and subjected to steam distillation. [2]
The leaves are in fascicles of three, [6] needle-like, yellow-green, twisted, and 9–15 centimeters (3 + 1 ⁄ 2 –6 in) long. The cones are resin-sealed and irregularly shaped, [4] 8–16 cm (3 + 1 ⁄ 4 – 6 + 1 ⁄ 4 in) long and clustered in whorls of three to six on the branches. The scales end in a short stout prickle.
The oldest of this species is more than 4,800 years old, [1] making it the oldest known individual of any species. Many scientists are curious as to why this tree is able to live so long. In one study, they discovered that Pinus longaeva has higher levels of telomerase activity, which further slows or prevents the attrition rate of telomeres. [2]
The female cones are large and usually woody, 2–60 centimetres (1–24 inches) long, with numerous spirally arranged scales, and two winged seeds on each scale. The male cones are small, 0.5–6 cm (1 ⁄ 4 – 2 + 1 ⁄ 4 in) long, and fall soon after pollination; pollen dispersal is by wind. Seed dispersal is mostly by wind, but some ...
As to the identity of the twin objects, the "cone" is generally recognised as a Turkish pine cone (Pinus brutia), common in Assyria.Other common identifications suggest the male inflorescence of the date palm (Phoenix dactylifera), or a clay imitation of one or the other. [2]
Monocentris japonica, the Japanese pineapplefish, is a pinecone fish of the family Monocentridae, found in the tropical Indo-West Pacific Oceans, at depths between 2 and 100 m and can be found on both rocky and coral reefs. The fish is nocturnal and shelters in caves and under ledges during the day. [1]
