Jomblang Cave

Jomblang Cave or Luweng Jomblang is a 50-meter vertical collapse doline type cave in Gunung Kidul Regency, Yogyakarta Province, Indonesia. This cave was formed due to geological processes in which soil and vegetation on the surface collapsed to the bottom of the earth into a sinkhole thousands of years ago into ancient forests in the cave. Inside the cave grows endemic vegetation and a place for conservation of ancient plants. Sunlight bursts into 90 meters of Luweng Grubug to form a light pole, illuminating the beautiful flowstone and water dripping from a height in a dark room. Characteristics Jomblang Cave is one of the caves of hundreds of caves in the Gunung Sewu Geopark . This doline collapse cave is formed due to the surface process collapsing and forming a sinkhole. Ancient plants that lived on the surface also fell to the bottom of the earth, adapted and continued to grow until now as a very rare endemic plant. This cave has a mouth hole 50 meters wide and 60 meters ...

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...
