Accidentally I saw a crowd of ants, which seemed to move their nest. They flock like long marched from one place to another place. I notice actually they walk in two-way, and they meet from opposite directions when they stopped andsomething like a message to fellow ants meet each other.
At the time I was smoking a cigarette, and went through my mind, what happen if I block the track by smoke dust. Intentionally every time my cigarette ashes , then I deliberately dropped in their path. As the ash was little like they are not disturbed, and the line still goes both ways smoothly without any interruption. The more I scatter the ashes in their path, they began frantically looking for a way, and it seems many of them are lost. They did not find the path, even they do not meet with his friends in the opposite direction. The longer the number of ants can through the smoking dust become less. In the end they did not meet each other and nothing else is passing.
From this I conclude from my accidentally experiment that the smell of smoke of cigarette that I'm stocking up with smoke dust strongly influences their communications, although the dust is not hot and not to kill ants, but apparently the smell of cigarette dust break and cut off the communication between the ants. After 1hour later the ants were no longer a through route, even after this blog have written no longer ant in the path.

Penguin
Else Animals:
Penguins are stout bodied, short legged, flightless birds superbly adapted for swimming underwater. Their wings resemble flippers and their bodies are covered with short, scaly feathers with downy bases. All 6 genera and 18 species, in the family Spheniscidae, are blackish above and white below, but some are banded across the breast (Spheniscus) and others have ornamental yellow crests (Eudyptes). Penguins are found in the colder waters of oceans of Southern Hemisphere, breeding near the equator on the Galapagos Archipelago, in southern Sourth America and Africa. In Australia and New Zealand, and on many island. Only two species, the adelie and the emperor, breed in Antarctica.
Penguins swim underwater with powerful strokes of their wings and use their webbed feet and stiff tail as rudders. Sometimes they make a series of porpoiselike leaps from the surface at speeds approaching 40 km/h (25 mph). Although penguins feed mainly on small crustaceans (krill), fish and squid near the surface, the emperor penguin may descend up to 260 m (850 ft) in search of food.
Penguins gather into large colonies to breed, returning year after to the same rookery. The female emperor penguin lays her egg in May and then goes to sea to feed while the male incubates continuously for two months without eating. He stands on the Antarctic ice in the perpetual darkness of winter, holding the egg on his feet under a fold of abdominal skin. When the females returns to care for the newly hatched chick, the male goes to sea to regain his lost weight. The downy chicks hard together into creches by warmth and protection as they get older. Chicks feed by reaching into their parents throats for food that is brought from the sea.

Cicada
The Cicada is a blunt headed stout bodied, winged insect of the family Cicadadae, order Homoptera, which also includes aphids and other feeders on plant saps. In North America, where cicadas are also called harvest files and locusts, the typical loud buzzing or whistles of the males insects may be heard in trees from June through September.
The Cicada sound is made by specialized structures on the abdomen and apparently serves to attract females (and predators). After mating, females deposit eggs in slits they cut into twigs and thereby sometimes damage orchard and ornamental trees. Eggs hatch into nymphs, which drop to the ground and burrow into the soil, where they obtain juices from roods of trees and shrubs with their sucking mouth parts. Depending on the species, cicada nymphs remain underground from 1 to 17 years, then emerge.
Cicadas are benign to humans under normal circumstances and do not bite or sting in a true sense, but may mistake a person's arm or other part of their body for a tree or plant limb and attempt to feed.[2] Cicadas have a long proboscisunder their head which they insert into plant stems in order to feed on sap. It can be painful if they attempt to pierce a person's skin with it, but it is unlikely to cause other harm. It is unlikely to be a defensive reaction and is a rare occurrence. It usually only happens when they are allowed to rest on a person's body for an extended amount of time.
Cicadas can cause damage to several cultivated crops, shrubs, and trees, mainly in the form of scarring left on tree branches while the females lay their eggs deep in branches.
