While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink(臭气)too.
Vulture(秃鸳)
Vultures, are street sweepers that feast on the rotting flesh of dead animals, which benefits us by ridding our highways and landscapes of animal bodies and the bacteria they might carry. When vultures feel threatened they vomit, and the smell of vomited-on dead bodies puts of most predators. Throwing up allows the vulture to fly away more quickly-and the vomit can hurt the aggressor's eyes and face.
Opossum(负鼠)
In some ways opossums have it easy. In order to become “dead\to fax anyone a death certificate. They just lie there with their tongues hanging

Hoatzin(磨雉)
Hold your nose and meet the hoatzin, a bird of distinctions, not the least of which is that it smells like fresh cow shit. The animal mostly eats leaves and it's the only bird known to digest by fermentation, like a cow. This process is what causes its smell and has earned it the nickname the “stink bird
Millipedes (千足虫)
Millipedes are tricky. For starters they look wormy. Their name is deceptive, too: Their legs number about 750. Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.
Sea Hare(海兔)
The graceful sea hare is plain in taste in the first place, so it's not the most popular dish in the seafood chain. Nonetheless this type of sea creature has a pretty creative smell-related defense that is almost the opposite of its smelly companions on this list. The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.
Researchers using lobsters(2-f)as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don't know how appealing it is. 60. The sea hare defends itself from predators by ____. A. becoming plain in taste at the discovery of a predator B. giving out purple ink to make itself invisible to predators C. releasing substance to make predators unable to smell it D. giving off smelly gas to try to drive predators away.

ARCHAEOLOGISTS(考古学家) GUIDED BY laser images of a remote region of northern
- 23 -
Guatemala have discovered 20-foot-high walls, watchtowers, and other evidence that ancient Maya societies had been annoyed by warfare threat over many years. The finds have upended long-established impressions of a civilization that it tamed the jungle and built thriving cities,then declined and disappeared quietly beneath the dense tropical forest.
Among the most surprising discoveries was a large stone complex now called La Cuemavilla. Built on a steep ridge, the heavily fortified site included high walls. Moats which serves as the largest defensive system ever discovered in the region.
This was surprising says an archaeologist, \romanticize Maya warfare as something that was largely ritualized. But the fortifications were seeing suggest an elevated level of antagonism over centuries. Rulers were so deeply alarmed that they felt the need to invest in all these hilltop fortifications. There is an almost visible sense of fear in this landscape.
All these findings owe credit to PACUNAM LIDAR Initiative, a laser survey of some 800 square miles of the Maya Biosphere Reserve in northern Guatemala. Using revolutionary Laser technology, the survey revealed the long-hidden ruins of a sprawling pre-Columbian civilization that was far more complex and interconnected than most Maya specialists had supposed.
Guided by the new Laser treasure maps, the LIDAR team deployed through the jungle over the past year to conduct hands-on investigations of more than a dozen of the most promising sites-most of which would have been imperceptible without LIDAR.
\who's part of the PACUNA project. But LIDAR picks up the patterns and makes the features pop out with surprising clarity.
Three-dimensional maps generated by the survey yielded surprises even at Tikal, the largest and most extensively explored archaeological site in Guatemala. The ancient city was at least four times bigger than previously thought, and surrounded by a massive ditch and fortified base stretching for miles.
Archaeologists stress that LIDAR, for all its utility, will never see below the ground or yield direct dates of occupation. “we still need to dig and hack our way
