Rain tree (Albizia saman)

Trembesi or Ki Hujan or monkey pod tree or rain tree or Samanea saman (Albizia saman) are species in Fabaceae, grow as large trees, tall, umbrella canopies and are very wide, flowering and bearing fruit, roots absorb a lot of water, popular as a shade and scattered throughout the tropics.

A. saman grows 30-40 m, stem diameter is 4.5 m and tree crowns can be 40-60 m wide. Tree trunks are sometimes bent, narrowed or bulging. The bark is grayish brown and smooth when young, but tanned, very rough and peeling when old.

Dlium Rain tree or monkey pod tree (Albizia saman)

The leaves are compound, pinnate bones, flat edges, elongated round shape, 2-6 cm long, 1-4 cm wide, dark green, slippery surface, the bottom has velvety, soft and 7-15 cm long stems. Light sensitive leaves that will close when it rains and at night where the tree is also called the "Tree at 5 pm".

White flowers and pink patches on the upper hair, up to 10 cm long from the base to the ends of the hair. Crown tube measuring 3.7 cm and 20-30 stamens which have a length of 3-5 cm. Nectar to attract insects to encourage pollination. Hundreds of flowers develop simultaneously filling the canopy.

Straight pods slightly curved, hard skin, 10-20 cm long, 1.5-2 cm wide and 0.6 cm thick. The fruit is blackish brown when ripe. Seeds number 5-25 items, length 1.3 cm, ellipsoid, flat, fat embedded in a reddish brown rag, very sticky and sweet.

The striking characteristic of a monkey pod tree is that branches form an umbrella that grows wider than height. A trembesi tree absorbs 28.5 tons of CO2 per year while other tree species only 1 ton of CO2 in 20 years. This tree also decreases gas concentration without greening and absorbs strong groundwater.



Rain tree grow quickly and are spread in the tropics with an average rainfall of 600-3000 mm / year, altitude 0-500 meters, various types of soil with a pH of 4.7 to 8.5 and able to survive 4 months without rain with a temperature of 20 -38C.

Tree trunks are used for building construction materials and leaves are extracted to treat skin diseases. Litter to reduce aluminum concentration, increase pH and absorb nitrogen content for the soil. Seeds are used as a laxative and are processed into nuts.

Ki Hujan Cultivation uses seeds soaked in water at 80C for 1-2 minutes and dried. Then immersed in water at a temperature of 30-40C for 24 hours to accelerate germination up to 90-100%. Sprouts ready for planting have a length of 20-30 cm.

A deep-sea isopod Bathyopsurus nybelini adapted to feed submerged Sargassum algae

NEWS - Incredible footage shows a marine species, Bathyopsurus nybelini , feeding on something that sinks from the ocean’s surface. Researchers using the submersible Alvin found the isopod swimming 3.7 miles down using its paddle-like legs to catch an unexpected food source: Sargassum. Researchers from Woods Hole Oceanographic Institution (WHOI), the University of Montana, SUNY Geneseo, Willamette University and the University of Rhode Island found the algae sinking, while the isopod waited and adapted specifically to find and feed on the sinking nutrient source. The Sargassum lives on the surface for photosynthesis. The discovery of a deep-sea animal that relies on food that sinks from the waters miles above underscores the close relationship between the surface and the deep. “It’s fascinating to see this beautiful animal actively interacting with sargassum, so deep in the ocean. This isopod is extremely rare; only a handful of specimens were collected during the groundbreaking Swedis

Ngamugawi wirnagarri reveals evolution of coelacanth fish and history of life on earth

NEWS - An ancient Devonian coelacanth has been remarkably well preserved in a remote location in Western Australia linked to increased tectonic activity. An international team of researchers analysed fossils of the primitive fish from the Gogo Formation of Ngamugawi wirngarri , which straddles a key transition period in the history of coelacanths, between the most primitive and more modern forms. The new fish species adds to the evidence for Earth’s evolutionary journey. Climate change, asteroid strikes and plate tectonics are all key subjects in the origins and extinctions of animals that played a major role in evolution. Is the world’s oldest ‘living fossil’ the coelacanth still evolving? “We found that plate tectonic activity had a major influence on the rate of coelacanth evolution. New species are more likely to have evolved during periods of increased tectonic activity when new habitats were divided and created,” says Alice Clement of Flinders University in Adelaide. The Late Dev

Integrative taxonomy reveals presence a new species West African mane jelly (Cyanea altafissura)

NEWS - A new species of Cyanea is described from samples collected in the Gulf of Guinea during 2017-2019. The species is a member of the nozakii group that has discontinuous radial septa and is characterized by, among other things, deeper rhopalial than velar marginal clefts, uniform papillose exumbrella, up to 200 tentacles per cluster and a dense network of anastomosing canals in a broad quadrate fold. West African mane jelly ( Cyanea altafissura ) can be genetically distinguished from relatives in the ITS1 and COI regions as confirmed by several phylogenies and other analyses. This is the first record of a member of the nozakii group in the Atlantic Ocean and the first description of a genus Cyanea from the west coast of Africa and the tropical Atlantic Ocean. Cyanea PĂ©ron & Lesueur (1810) currently includes 17 species and is the second largest number of valid and recognized species in the Semaeostomeae of Agassiz (1862), after Aurelia Lamarck (1816). Both genera are rarely re
