Rubyung (Pyrrosia longifolia)

Rubyung (Pyrrosia longifolia) is a plant species in Polypodiaceae, an epiphytic fern that grows vines on a large tree to form dense colonies and covers the tree trunk, grows wild in the shade of forest canopy, sometimes in open areas, plantations and neglected lands.

P. longifolia has fibrous roots with rhizomes. Stems in the form of a rhizome that grow creeping, long, dark brown, 3 mm in diameter and densely noisy. Ptiolus blackish brown, 10-15 mm long, 4 mm diameter and has trichomes.

The leaves are green, slightly thick, linear in shape, flat edges, smooth and shiny top surface. Sterile has an oblong shape and a widened center, 20 cm long and 2.5 cm wide. Fertile has a rounded tip, is 35 cm long and 3 cm wide.

Sorus sticks to the lower surface, is round in shape, clustered on some of the upper leaves and is brown in color. The scales on the rhizome are oblong-ovate, 2-3 mm long, dark brown in the middle, flat, yellowish-white, and have more than 100 hairs. Trichomes of sterile ptiolus and leaves are stelata, 8-9 arms and white in color.

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.

Hairy senna (Senna hirsuta)

Hairy senna ( Senna hirsuta ) is a species of plant in the Fabaceae family. It is an upright shrub, growing up to 2.5 meters tall. The leaves are compound on petioles up to 13 cm long. They usually have 2-6 pairs of leaflets, are egg-shaped, and have white hairs, up to 10 cm long and 5 cm wide. The flowers are yellow and arranged at the tips of branches and in the upper leaf axils in clusters of 2-5. The petals are 12-16 mm long, have 6 stamens, 3-8 mm long anthers, and 4 staminodes. Flowering occurs almost monthly. The pods are cylindrical, up to 15 cm long, 4-6 mm wide, and curved.

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...
