Berengan (Begonia hirtella) is a species of plant in the Begoniaceae, creeping and climbing shrub with branched stalks, all hairy, flowers at the ends of long and branching stalks, growing horizontally and vertically on the ground or rocks in shady or damp places.

B. hirtella has a stem that is cylindrical, long, soft, branched, whitish green or reddish green and has long white hairs. The branching of the stem will become a long stalk and end at a leaf.



The leaves are elliptical, oblique, pulses in all directions forming deep trenches on the top and uneven margins. The upper surface is hairy, rough and green or yellowish in color. The lower surface is hairy, rough and lighter in color.

Flowers grow at the ends of long, branchy stalks. The flower buds are triangular, flat and the surface has a bright green color. The flowers bloom white or yellowish green with a bright yellow sari in the center.

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 ...
