Crystal bell orchid (Didymoplexis pallens)

Crystal bell orchid (Didymoplexis pallens) is a species of plant in the Orchidaceae, terrestrial mycotrophic orchid, leafless, having a fleshy rhizome, single and erect stem, 6-25 cm tall, branched, cylindrical and white or cream in color.

D. pallens has white, trumpet-shaped flowers with sepals and petals similar in size and shape and fused about half the length, 6-8 mm long, 8-10 mm wide.

The labellum is wedge-shaped, 6-7 mm long and 9-10 mm wide with the sides curved upwards. There were two or three rows of callus along the midline of the labellum.

Crystal bell orchid grows in the shade, under clumps of bamboo, moist soil and black clay deposits. Plants appear during the first rains of the rainy season or at the end of the season. Flowers open only one day. The emergence of this orchid is triggered by the right and balanced symbiotic relationship with microorganisms.

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 ...
