Javan millipede (Remulopygus javanicus)

Javan millipede or keluwing or luwing (Remulopygus javanicus) is an animal species in Harpagophoridae, cylindrical and elongated, 150 mm long, 15 mm wide, consisting of 60 segments, each of which has two pairs of legs, black and brown with reddish legs.

R. javanicus has a round head with a size smaller than the body segments, the end segment at the tail has a reddish-brown tapered horn, a pair of reddish brown antennae, the whole body has a smooth and shiny surface.

Javan millipede moves slowly and when touched will quickly roll itself up with the legs placed on the inside. Keluwing is a herbivore, eating plants to get all the nutrients. including fruit, wood and dry leaves, but sometimes also parts of living plants.

Generally foraging at night, but sometimes found wandering around in the morning. Keluwing breed in burrows to lay eggs, after which the burrows are closed, then abandoned. They spend most of their time in underground pits and tunnels to rest.

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...
