Large-billed crow (Corvus macrorhynchos)

Gagak hutan or jungle crow or large-billed crow (Corvus macrorhynchos) is a bird species, distinctive in vocal, morphological and genetic. At least 9 subspecies are C. m. colonorum, C. m. connectens, C. m. intermedius, C. m. japonensis, C. m. macrorhynchos, C. m. Marxchuricus, C. m. osai, C. m. philippinus and C. m. tibetosinensis.

C. macrorhynchos is very adaptable and survives in various food sources. The overall size is 46-59 cm, has large bills and body proportions vary subspecies. The bill is large, relatively long, the top is thick and curved. Call loud and echoing. They are social animals and have a linear dominance hierarchy based on individual recognition.

Dark gray fur on the back, neck, shoulders and body at the bottom. Wings, tail, face and throat are shiny black. Large-billed crow inhabits forests, parks, plantations and cities. Flexible diets include sources on land and in trees, live and dead, plants and animals.

Jungle crow collects branches, grass roots, wool, cloth, vegetable fibers and even metal wires to make nests in pine forks. Females lay 3-5 eggs and incubated for 17-19 days. An oval with a smaller tip, hard and smooth surface, blue-green, speckled and reddish-brown stripes, pale sepia and gray.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Sweetpotato bug (Physomerus grossipes)

Kutu ketela or sweetpotato bug ( Physomerus grossipes ) is an insect species in Coreidae, brown with black legs, adults growing about 2 cm long, oval shaped, segmented antennas, heavily veined membranes, metathoracic odor glands and enlarged rear tibia. P. grossipes generally live in Leguminosae and Convolvulaceae especially sweet potato ( Physomerus grossipes ), pink morning glory ( Ipomoea carnea ), purple beans ( Vigna unguiculata ), Asian pigeonwings ( Clitoria ternatea ) and common bean ( Phaseolus vulgaris ). Sweetpotato bugs suck liquid from the stem which causes plants to wither and disrupt fruit production. P. grossipes places eggs at the bottom of the leaves or stems or grass around them. Females are very protective of their children, keeping eggs and nymphs from predators as the most famous example of maternal care in Coreidae. Even so, about 20% of eggs are eaten by predators such as ants and 13% are lost by parasitoid predation by chalcid wasps which lay eggs in egg...

Javan broadhead planarian (Bipalium javanum)

Cacing palu or Javan broadhead planarian ( Bipalium javanum ) is a species of animal in Geoplanidae, hermaphrodite, living on the ground, predators, often called only hammerhead or broadhead or shovel worms because of wide heads and simple copulatory organs. B. javanum has a slim stature, up to 20 cm long, up to 0.5 cm wide, head wide up to 1 cm or less, small neck, widening in the middle and the back end is rounded, all black and shiny. Javan broadhead planarians walk above ground level by raising their heads and actively looking left, right and looking up using strong neck muscles. Move swiftly, track meander, climb to get through all obstacles or make a new path if the obstacle is too high. Cacing palu track and prey on earthworms and mollusks. They use muscles and sticky secretions to attach themselves to prey to lock in. The head and ends of the body are wrapped around and continue to close the body to stop prey reactions. They produce tetrodotoxins which are very strong...
