Ranela (Selaginella plana)

Ranela or Asian spikemoss (Selaginella plana) is a species of plant in Selaginellaceae, fibrous roots, creeping in the forest, stems 0.5-1 cm in diameter, yellowish brown and slightly grooved, used by local residents as an antidote to demons and treat poisonous snake bites.

S. plana has green leaves with small and simple sizes that resemble flat scales, smooth surface, encircling the trunk and on the side branches arranged in four rows where the two side leaves consist of large leaves that fall off easily and two front rows of small, attached leaves.

Leaves are not stemmed, appear crossed, smooth surface. Ranela produces two types of spores that are not the same size. Sorus grows at the tip of the terminalia. Sporangia in fertile axillary leaves. The sporophyll is larger than the sporangia, collected into rectangular and sometimes slightly flattened terminal grains.

Shaded terrestrial at an altitude of more than 200 m in the tropics. Often used as an ornamental plant. In some areas it is used as a wound medicine, blood purifier, stomachache medicine and fever medicine by bathing using boiled water.

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...

Awar awar (Ficus septica)

Awar-awar or lagnob or hauli tree or barabar or sirih popar or tobo tobo ( Ficus septica ) is species of plants in Moraceae, trees grow in bushes or in neglected places and sap contained in roots, twigs, leaves and fruit is used to treat poisoning and digestive problems. F. septica is usually 1-5 m high, although in the forest it can be up to 25 m. Round, hollow and bare branches. Roots, twigs, leaves and fruit will emit a yellow sap and sticky if injured. The base of the leaves is large and spiky, arranged alternately or face to face with a stem length of 2.5-5 cm.
