Monkey pod tree (Samanea saman)

Trembesi or rain tree or monkey pod tree (Samanea saman) is a species of plant in the Fabaceae, a large tree, 30-40 meters high, 4.5 meters in diameter, tree crown 40-60 meters, irregularly shaped trunk, sometimes bent and swollen big.

S. saman has compound leaves with stalks about 7-15 cm long, 4-5 cm wide, dark green in color, the lower surface is velvety and soft. The leaves will fold when it rains and at night.

Flowers are white and bright red spots on the top, 10 cm long from base to tip. The crown tube is 3.7 cm long and has 20-30 stamens 3-5 cm long. Nectar for insects are very fond of.

The pods are straight, slightly curved, 10-20 cm long, 1.5-2 cm wide and 0.6 cm thick. The fruit is dark brown when ripe. Seeds embedded in reddish-brown flesh, very sticky, sweet containing 5-25 seeds with a length of 1.3 cm.

Trembesi absorbs 28.5 tons of carbon dioxide every year which an ordinary tree absorbs only 1 ton in a 20 year lifetime. This tree is also able to reduce gas concentrations effectively, without reforestation and has a strong ability to absorb groundwater.

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 ...

Bright white flat-backed millipede (Trichopeltis jiyue) like moon emerging from behind dark rain clouds

NEWS - Bright white flat-backed millipede ( Trichopeltis jiyue sp. nov.) from Ailaoshan National Nature Reserve in Yunnan Province, is the second recorded epigean species of Trichopeltis Pocock 1894 in China. Jiyue (Chinese spelling) refers to the bright white appearance of the animal, like the moon emerging from behind dark rain clouds. Polydesmida is one of the most diverse orders of Diplopoda (millipedes) with about 5000 species in 30 families and is widely distributed worldwide. All Polydesmida are blind, eyeless and metaterga usually show small to prominent lateral paranota or paraterga. Cryptodesmidae Karsch 1880 is a family Polydesmida with about 40 genera and 130 species distributed in the Neotropics (Mexico to Argentina), Afrotropics (continental sub-Saharan Africa) and Asia-Australasia (Central Asia and the Himalayas to Japan and Papua New Guinea). In tropical or subtropical Asia and Australasia, 12 genera and 36 species have been documented in Cryptodesmidae. Trichopeltis P...
