This week I encountered with 2 photos of animals in a state of shock.
My daughter sent me via Whatsapp another image of an elephant, and a friend shared many other by mailing list.
The surprise is a reflection of the unexpected. Maybe of thing or events that potentially knows what will happen, but that puts us in activity for the moment or the way presented.
In animals the surprise is an instinctive act of supervicencia.
Humans should seek for good things in surprise; she would symptom of track.
Sure, I do not expect to be surprised by a nuclear bomb. Although, I think, would not be a surprise, it would be a disappointment never consecrated.
Engineers and evolutionary biologists in Scotland and France recorded the boatman—which is roughly the size of a grain of rice—”singing” in a tank. The aquatic insect’s songs peaked at 105 decibels, roughly equivalent to the volume of a pounding jackhammer within arm’s reach.
The chirps are loud enough that humans can hear the sounds while standing at the edge of a boatman’s pond. Fortunately for nature lovers, though, nearly all the sound is lost when the noises cross from water to air.
Remarkably, the boatman creates his songs by rubbing his penis against his belly, in a process similar to how crickets chirp. Sound-producing genitalia are relatively rare within the animal kingdom, but animals have evolved hundreds of other ways to boost their hoots, howls, and snaps.
Did you ever read about loudest animals of the world? Well, we have selected an article from Nat Geo containing a list of world’s loudest animals.
The Howler Monkey
The howler monkey is the loudest land animal. Its calls, which some say are actually more like growls, can be heard up to three miles (five kilometers) away.
The monkey’s volume comes from its enlarged hyoid bone, a U-shaped bone in the howler’s throat that “isn’t actually hooked to any of the [other] bones, so it kind of just hangs there,” said Dell Guglielmo, caretaker for two howler monkeys at the National Zoo in Washington, D.C. The enlarged bone creates a throat sac in which the monkey’s calls resonate before booming out.
Only the males of the common coqui frog sing, but their calls, recorded at peaks of a hundred decibels from three feet (a meter) away, make them the loudest known amphibians.
The nocturnal frog’s two-part “co-qui” call has a two-part meaning: Other male frogs respond to the territorial “co” part of the call, while females are attracted to the “qui.”
In the coqui’s native habitat of Puerto Rico, the frogs are considered part of the island’s natural heritage. But in Hawaii, where the frogs are quickly establishing themselves as an invasive species, residents have spent many sleepless nights due to the noisy frogs, which, in aggregate, are comparable to a lawnmower running all night.
The Blue Whale
The blue whale is the loudest mammal of them all, with vocalizations that reach 188 decibels.
Blue whales don’t have songs as complex as those of humpback whales, but their low-frequency “pulses”— some below the range of human hearing—have been recorded more than 500 miles (805 kilometers) away.
A few years ago researchers found that the whales had been lowering the frequencies of their songs even more—by up to 30 percent since the 1960s in some populations. One theory suggests that the whales no longer need to sing at “high” pitches to be heard at a distance, because the species, while still endangered, has rebounded since whale hunting was banned in 1966.
The Snapping Shrimp
The snapping shrimp doesn’t sing, chirp, wail, or hoot, but it just might be responsible for the loudest noise produced by any living being.
These shrimp stun prey by closing their specialized claws quickly enough to shoot jets of water out at 62 miles (100 kilometers) an hour, forming a low-pressure bubble of vapor behind the jet. When that bubble collapses, it produces a hot, loud mini-explosion of 200 decibels, which stuns or even kills the shrimp’s dinner.
You wouldn’t want to be around when oilbirds come home to roost—these cave dwellers, the loudest known birds, can be deafening when gathered in large groups.
Oilbirds use echolocation to navigate in completely dark caves. But, unlike the calls of most bats, the birdcalls are within the range of human hearing. Each bird can produce squawks and clicks up to a hundred decibels at close range, and colonies can contain thousands of birds.
The oilbirds appear to use echolocation only within their cave homes and not during their nocturnal foraging. This could be because their sensitivity isn’t very high: In one experiment, oilbirds flew straight into plastic discs that were 4 inches (10 centimeters) wide, but they were able to avoid 8-inch (20-centimeter) disks and larger.
The Mole Cricket
The mole cricket species Gryllotalpa vinae is the loudest of the insects. The critter uses its specialized front legs to dig a megaphone-shaped burrow. Standing inside that dugout, a cricket can chirp loudly enough that humans can hear it nearly 2,000 feet (600 meters) away.
Microphones placed three feet (a meter) from a cricket’s burrow entrance have recorded peak sound levels of 92 decibels, or about the volume of a lawn mower.
In fact, using the burrow, G. vinae is able to turn an astonishing 30 percent of its energy into sound.
The relationship of boys with nature is essential for their growth. The games allow children to learn that “about this world”. Play earth, wood, trees or water not only make them happy, regardless of the game. It is the experience with the world, its textures, smells and colors.
But the interaction with animals and pets, come into play another link. As in life, this link is between love and hate. It is not friendship either, on the other end, is fear. Of course curiosity is given.
I’ve been thinking, and I can not define. So call it “natural relationship.”
What I do believe it is natural that this relationship brings to children that learning is much more intelegent the animal. It can, within a certain framework, dominate or shape. But he also learns of the affection, protection, care, force of nature, trust and fear.
I’m not willing to lose my children that learning opportunity. Of course the first is our children, but there is more to do.
For reflection. I leave you some sweet pictures of kids and animals.
The axolotl is a Mexican neotenic mole salamander. Neotenic means that, as adults, it holds onto traits seen in juveniles. Axolotls are used extensively in scientific research due to their ability to regenerate most body parts, ease of breeding, and large embryos.
With 2,500 species of cicada insects around the world, some are stranger than others.
The aye-aye is a rodent-looking lemur found in Madagascar that combines rodent-like teeth with a long, thin middle finger to fill the same ecological niche as a woodpecker.
4. Star-nosed Mole
The star-nosed mole is a small North American mole found in eastern Canada and the north-eastern United States, with records extending along the Atlantic coast as far as extreme southeastern Georgia.
5. Philippine Tarsier
The Philippine Tarsier, known locally as the Maumag in Cebuano/Visayan, is an endangered tarsier species endemic to the Philippines. It is found in the southeastern part of the archipelago, particularly in the islands of Bohol, Samar, Leyte, and Mindanao. Its name is derived from its elongated â€œtarsusâ€ or ankle bone.
6. The angora rabbit
The angora rabbit is a domesticated species, known for its cultivated hair. The Angora is one of the oldest types of domestic rabbit, originating in Ankara, Turkey, along with the Angora cat and Angora goat.
7. Giant Isopod
Giant isopods can be found in cold and deep sea, primarily in the Atlantic.
8. Kiwa hirsuta (Yeti Crab)
This crustacean was discovered in the South Pacific Ocean in 2005 and is noted for its â€œfur-likeâ€ extensions. This decapod, which is approximately 15 cm (6 inches) long, is notable for the quantity of silky blond setae (resembling fur) covering its pereiopods (thoracic legs, including claws). Its discoverers dubbed it the â€œyeti lobsterâ€ or â€œyeti crab.â€
9. Leafy Sea Dragon
The name is derived from the appearance, with long leaf-like protrusions coming from all over the body. These protrusions are not used for propulsion; they serve only as camouflage. The leafy sea dragon propels itself by means of a pectoral fin on the ridge of its neck and a dorsal fin on its back closer to the tail end. These small fins are almost completely transparent and difficult to see as they undulate minutely to move the creature sedately through the water, completing the illusion of floating seaweed.
They are benthic creatures, living at extreme depths: 3000-4000 meters, and are some of the rarest of the Octopoda species.
