Penguin Facts: Species, Behavior, Habitat & Adaptations
Penguins are flightless seabirds found primarily in the Southern Hemisphere. Their streamlined bodies, flipper wings, and unique adaptations make them excellent swimmers.

Tigers are the largest cat species and apex predators with distinctive orange and black stripes. Only 4,000 remain in the wild across 13 Asian countries.

Tigers are larger than lions, making them the biggest cat species on Earth. Siberian tigers reach 660 pounds while male lions max out around 550 pounds.
Tiger stripes are not just fur patterns. Each tiger has a unique stripe pattern functioning like fingerprints, allowing researchers to identify individuals from photographs. These vertical stripes provide camouflage in tall grass and forest shadows by breaking up the tiger's outline, making a 660 pound predator nearly invisible to prey.
Unlike domestic cats that hate water, tigers are powerful swimmers that actively seek out water. They swim across rivers several miles wide and hunt aquatic prey including fish and turtles. This swimming ability separates them from most other big cats, though jaguars also swim well.
Tiger bite force reaches 1,050 PSI, stronger than lions at 650 PSI. Combined with 3 inch canine teeth, this creates devastating killing power. Tigers typically kill prey by clamping jaws around the throat and suffocating victims or severing the spinal cord with a precise neck bite.
The Bali tiger, Caspian tiger, and Javan tiger all disappeared in the 20th century. The South China tiger is functionally extinct with no confirmed wild sightings since the 1970s. The Malayan tiger numbers fewer than 150.
Despite zero scientific evidence, traditional Chinese medicine falsely claims tiger parts cure ailments. This pseudoscience drives illegal poaching that kills hundreds of tigers annually. Tiger bones, skins, and organs sell for thousands of dollars on black markets.
Tiger numbers crashed to 3,200 in 2010, bringing them to the edge of extinction. Intensive conservation efforts in India, Russia, and Nepal achieved modest recovery to approximately 4,000 tigers today. These successes prove dedicated conservation works, though tigers still occupy less than 7% of their historic range.
Tigers once ranged from Turkey to the Russian Far East across 30 countries.
Three subspecies went extinct in the 20th century: Bali, Caspian, and Javan tigers.
Tigers have featured prominently in Asian art, mythology, and culture for millennia.
The 1973 Project Tiger in India became one of the first major wildlife conservation programs.
Tiger populations crashed from 100,000 in 1900 to just 3,200 by 2010.
Research proved tiger stripes extend to the skin, not just fur, and are unique like fingerprints.
Studies showed tigers are excellent swimmers who actively hunt in water unlike most cats.
Scientists documented tiger roars carrying up to 2 miles through forests.
Research revealed tigers can leap 30 feet horizontally and 12 feet vertically.
Studies showed tiger night vision is approximately 6 times better than humans.
Tigers symbolize power and royalty across Asian cultures from India to China.
The Year of the Tiger in Chinese zodiac occurs every 12 years.
Tiger conservation became a flagship effort for wildlife protection globally.
Illegal tiger trade drives poaching despite international bans.
Tiger tourism generates significant conservation funding in India and Nepal.
Before human expansion, an estimated 100,000 tigers roamed from Turkey across Asia to the Russian coast. Nine subspecies occupied diverse habitats from tropical jungles to snowy forests. Tigers were apex predators throughout their range with minimal human conflict.
After centuries of hunting and habitat destruction, tiger populations crashed to just 3,200 by 2010. Three subspecies went extinct. Tigers now occupy less than 7% of their historic range. Intensive conservation efforts have achieved modest recovery to about 4,000, proving dedicated protection works.

Bigger than lions. Siberian tigers reach 660 pounds while lions max at 550 pounds.
They can mimic prey calls. Tigers have been observed imitating deer sounds to lure victims.

Approximately 4,000 tigers remain in the wild today, a dramatic decline from an estimated 100,000 in 1900. The population reached a low of 3,200 in 2010 but has slightly recovered due to conservation efforts. All six surviving subspecies are endangered, with some numbering fewer than 150 individuals.
