Common carp (Cyprinus carpio)

Ikan mas or common carp (Cyprinus carpio) is a species of animal in Cyprinidae, long and slightly flattened to the side, living in freshwater, omnivores, very diverse colors, has long been known as a food source and ornamental fish that is widely cultivated because it is easy to breed and not much requires special treatment.

C. carpio has a mouth at the tip of the middle and can be puffed, has two pairs of tentacles of unequal length. The head has a pair of eyes, a pair of concave noses that are not connected to the oral cavity, gill slits and a pair of lids, hearing aids and balance that is visible from the outside.

Fins are paired and single as a device for moving. They eat moss, plankton and small invertebrates found at the bottom and edges of the water, but more commonly referred to as omnivores that tend to be herbivores.

The digestive tract in segments includes the mouth, oral cavity, pharynx, esophagus, pylorus, intestine, rectum and anus. Common carp with a length of 19 cm generally has a bowel length of up to 50 cm or almost three times the body length.

They do not have a stomach but the small intestine at the tip looks enlarged, better known as "fake stomach". The long intestine is a compensation for processing foods that have high fiber content and aims to get the maximum hydrolysis of food macromolecules.

Ikan mas grow optimally in freshwater habitats on the banks of rivers or lakes that are not too deep and the currents are not too heavy, altitude 150-600 m, temperature 25-30C and water pH 7-8, although sometimes found in brackish waters or river mouths with 25-30% salt content.



The life cycle begins with developments in the gonads that occur throughout the year and are not dependent on the season, but often at the beginning of the rainy season due to stimulation from the smell of dry and stagnant water.

Spawning in the middle of the night until the end of dawn in which the parents are actively looking for a lush place by water plants or grasses that cover the surface of the water as a place to attach eggs.

Eggs are round, clear in color, 1.5-1.8 mm in diameter and weights from 0.17 to 0.20 mg. Egg size varies depending on the age and size of the parent. Embryos will grow in eggs that have been fertilized by spermatozoa.

The eggs will hatch and grow into larvae with a size of 0.50.6 mm and weigh 18-20 mg after 2-3 days and have a large egg yolk bag as a food reserve for 2-4 days. Larvae tend to stick and move vertically.

The larvae enter the final stage within 4-5 days and start eating zooplankton such as rotifers, moina and daphnia which will spend about 60-70% of their own weight every day. After three months it turns into a teenager to weigh about 100 grams.

Adult fish come after six months weighing 500 grams for males and 1.5 kg for females. Parent has a habit of stirring the bottom of the water to find food. C. carpio has a variety of scales, body shapes and fins depending on variety.

Mashpi walkingstick (Trychopeplus mashpiensis) from Chocó, Ecuador, based on males, females and eggs

NEWS - Researchers report Mashpi walkingstick ( Trychopeplus mashpiensis Conle, Valero & Hennemann, sp. nov.) from the Chocó ecoregion of northwestern Ecuador is new to science based on its unique body ornamentation and egg structure morphology. Trychopeplus Shelford 1909 is a genus of Neotropical stick insects (Phasmida Leach 1815) known for its remarkable morphological adaptations that allow it to blend in almost perfectly with epiphytic lichens in its habitat. These adaptations make Trychopeplus one of the most cryptic stick insect genera. The genus was described to distinguish the Neotropical species from Pericentrus Redtenbacher 1908 based on morphological differences and distinct geographic distribution compared to the type species Pericentrus moewisi Redtenbacher 1908. Pericentrus is known to be restricted to East and South Asia, whereas Trychopeplus is endemic to the Neotropics.

Giant shield bug (Pycanum alternatum)

Giant shield bug or pycanum rubens ( Pycanum alternatum ) is a species of animal in Tessaratomidae, has a large shield covering the back, shiny green-blue-brown colored and appears to have a powder or wax layer, inhabiting the leaves of plants in open forests or bushes . P. alternatum is also called a stink bug because of its ability to release pungent aromas when disturbed. These insects live solitary with a partner and usually the mother gather in a family together in nymphs. White eggs are attached under the leaves of the plant. Nymphs can be found in the same host as their parent. The nymph has a flat rectangular shape with a large vein in the middle like a flat leaf. Nymphs having striking colors are light green, orange and red. Color may represent various stages of development or gender. The initial stage has a small size and red color. It grows in a bigger size and turns orange then ends in green. Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Hemipter...

Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...
