Giant sensitive plant (Mimosa diplotricha)

Rembet or nila grass or giant sensitive plant (Mimosa diplotricha) is a leguminous wood shrub species in the Caesalpinioideae, grown as erect shrubs or rock climbers, up to 3 m high and includes three varieties: Mimosa diplotricha diplotricha, Mimosa diplotricha odibilis and Mimosa diplotricha inermis.

M. diplotricha develops sensitive leaves and will fold if touched. The bipinnate leaves are bright green, hairy and sit alternately along the stem. Each leaf contains about 20 pairs of small sessile lancet leaflets facing each other. Each leaflet is 6-12 mm long and 1.5 mm wide.

Rembet has very long and square-shaped wooden trunks with four longitudinal angular backs. The rows of dense thorns are very sharp stretching along the ridge where each is 3-6 mm long. Flowers are pale pink, forming balls for a diameter of 12 mm and appearing from short stems in leaf joints. Flowers develop into seed pods and winding.

Each pod has a length of 10-35 mm and a width of 6 mm. The seeds are oval and flat for 2-2.5 mm long, 0.6-1.4 mm thick and light brown. Seeds are spread through water or attached to clothing and can last up to 50 years. Nila grass grows fast and is able to tolerate various soils and climates. They form very dense shrubs, very invasive and all parts of the plant are toxic to animals.

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...

Javanese grasshopper (Valanga nigricornis)

Wooden grasshopper or Javanese grasshopper ( Valanga nigricornis ) is an animal species of Acrididae, grasshoppers that have at least 18 subspecies, insects with very wide diversity in color and size, sexual dimorphism in which females are larger in size and paler in color. V. nigricornis in males has a length of 45-55 millimeters and females 15-75 mm. The head is square and green or yellow or brown or black in color. A pair of antennas has a black color. The eyes are large and gray or white or brownish. The hind legs are very large and have a green or yellow or brown or black color, plain or brindle. The limbs have two rows of large and long spines with black tips facing backward. The wings have a length exceeding the belly, a rough surface and are brown or green or yellow or black in color with pulse lines forming spaces filled with black color. The hind wings are rose red which will be visible when flying. Nymphs are pale green or yellow or brown or blackish in color. Javanese gr...
