Cavendish banana (Musa acuminata)

Pisang or cavendish banana (Musa acuminata) is a plant species in the Musaceae, a banana with small or seedless seeds, a evergreen perennial plant, the stems are composed of a layer of leaf sheaths that are tightly closed and emerge from completely buried tubers.

M. acuminata is formed as a pseudostem with a pile of leaf sheaths and is watery, soft, upright, up to 3 meters high, white or green to black in color and dries to brown, forming dense colonies by producing shoots around it.

The leaves are elongated, 120 cm long, 45 cm wide, watertight, a midrib in the middle and light green, the upper surface is dark green, the lower surface is whitish green with a flour coating.

Inflorescences grow horizontally or obliquely from the ends of the stems. Individual flowers are white to yellowish in color and are negative geotropic. The female flowers are located near the base and develop into fruit, the male flowers are located at the very top and are bud-shaped between the coarse bracts.

The fruits grow in bunches of up to 20 groups and each group has up to 20 fruits. Each fruit is up to 23 cm long, up to 4 cm in diameter and weighs up to 200 grams. Each fruit contains up to 62 small seeds or no seeds at all depending on the cultivar via natural mutations resulting from vegetative propagation.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Javan mocca or Javan slender caesar (Amanita javanica)

OPINION - Javan mocca or Javan slender caesar ( Amanita javanica ) is a mysterious fungus species and has been enigmatic since it was first reported by Boedijn in 1951 and after that no explanation or reporting of specimens is believed to be the same as expected. Boedijn (1951) described A. javanica which grew on Java island as having the characteristics covered in the Amanita genus. Corner and Bas in 1962 tried to describe Javan mocca and all species in Amanita based on specimens in Singapore. Over time some reports say that they have found A. javanica specimens in other Southeast Asia including also China, Japan, India and Nepal. But there is no definitive knowledge and many doubt whether the specimen is the same as described by Boedijn (1951). I was fortunate to have seen this species one afternoon and soon I took out a camera for some shots. In fact, I've only met this mushroom species once. Javan mocca is an endangered species and I have never seen in my experience in...
