Bamboo orchid (Arundina graminifolia)

Bamboo orchid (Arundina graminifolia) is a plant species in Orchidaceae, perennial terrestrial orchid, reed stems standing upright or horizontal, tubular, up to 2 m high, forming large clumps on forest slopes, agricultural land, plantations, roadsides and abandoned land.

A. graminifolia has linear leaves, grows along the stem, seated opposite, oblong lanceolate, 9-19 cm long, 1-1.5 cm wide, thick, a vein in the middle, pointed tip, amplexicaul sheath and dark green.

Clusters of flowers in slightly open terminals up to 10 buds, blooming successively at the terminals, 7-16 cm long. The flowers are 5-8 cm in diameter, reddish purple in color and white disc with purple lips. The bracts are broad triangular in shape and surround the main stalk of the flower bunch.

Fertilized seed pods will form small powdered seeds and small plants often develop near the tips after flowering, most likely aiding propagation if allowed to reach the ground.

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...
