Awned panick grass (Oplismenus compositus)

Awned panick grass (Oplismenus compositus) is a species of plant in the Poaceae, 15-150 cm long, leaves lanceolate or ovate, 2-16 cm long, 8-35 mm wide, strands veined and have transverse veins, pointed or slightly pointed ends. .

O. compositus has racema composed of inflorescences, grows on the side of the central axis, unilateral and 2.5-11 cm long. The middle inflorescence axis is 5-25 cm long with angular rachis and pilose at the bottom.

The spikelets are arranged in 2 rows, namely fertile, pedicelled and sessile. Stem oblong. The spikelet also has one basal sterile floret and one fertile floret. 2.5-4 mm long and lanceolate.

Glumes are shorter than spikelets and thinner than fertile lemmas. The bottom is ovoid with a tent length of 3-10 mm. The upper glume is ovoid, obtuse and 0-4 mm long.

The flower buds are 2-2.5 mm long, pubescent, emarginate and mucronate. The florets and glumes have a keel. Glume is 5 items and florets are 7-11 items. Fruit linear and 0.5 mm long.

Black jumping spider (Hyllus diardi)

Black jumping spider ( Hyllus diardi ) is an animal species in the Salticidae, black and white spiders, long hair, round head, elongated belly, relatively small, arboreal, perched on leaves in bushes and low trees in forests and agricultural lands. H. diardi has black and white color, shiny surface and white hair all over the body. The head is round, shiny black with a linear white line in the middle. Black eyes on the front of the head. The stomach has an elongated, jointed, black cylindrical shape with black plots at the top of each segment. The legs are long, segmented, shiny black or brownish in color and hairy. Black jumping spiders live arboreal, perch on leaf surfaces, low bushes, trees in forests, agricultural land, roadsides and shade. Very sensitive to human presence and will hide behind leaves to avoid sight.

Water strider (Ptilomera tigrina)

Water strider ( Ptilomera tigrina ) is an animal species in Gerridae, a predatory insect that spends time on the surface of fast water with back and forth movements with a speed of up to 1.5 m/s to float and is very easily recognized by its habit of always walking and jumping on around water. P. tigrina has an elongated, dark cylindrical body with several bright or silvery white parts. A pair of big eyes at the tip of the head. The stomach has joints and tapers towards the back. A pair of antennae is very long with several joints and stick-shaped legs. The forelegs pair have three sections with two joints and the first is slightly thickened. The second and third pairs of legs are several times the length of the body. Water strider has a very fast movement on the surface of the water to float and target prey near the surface. This species is a model in biophysical research regarding the ability to float on the surface and the ability to move forward quickly. The buoyancy originates f...
