困境中猎物的哀嚎能吸引附近区域中捕食者的注意。如果每一个捕食者都循声而来,那么可以想见会有激烈的竞争。体型小且群居的豺,体型大且独居的豹在这样的竞争中可能会吃亏,但它们还是可能会小心翼翼地在附近查看一番。豺就是如此,若是有大的捕食者正在进食,它们会在周围盘桓,小心推进,希望在对方鼻子底下偷一杯羹或是等对方饱食而去后再去吃残羹冷炙。体型小且独居的动物,如獾、薮猫、麝猫、非洲麝猫等,它们在这样的竞争中不仅仅可能被杀,更可能成为别人食物的一部分。所以它们对这种哀嚎的反应不是置之不理,而是当作危险信号,它们会及时离开以躲避大群即将到来的大型捕食者,这也是表格所显示的。大体型且群居的狮子,得益于它们的力量和数目,在竞争中最为有利。其他能与狮子分庭抗礼的就是斑鬣狗了。斑鬣狗不仅在常规猎杀中常常挑战狮子,它们也会被动物的哀嚎所吸引。其他的捕食者往往会避开斑鬣狗和狮子的争斗以避免自身受到牵连。

为了进一步说明情况,拉布雷亚沥青坑中的遗骸被按照与非洲生态系统实验中相同的方式分类。沥青坑中的样本与非洲生态系统中的种群并不具可比性,但还是能用类似的方法去分析。如果剑齿虎是独居动物,那么结果就是上表中的C列,如果剑齿虎是群居动物,那么结果就是上表中的D列。这两列的结果,和B列中的结果相比,很明显地支持剑齿虎的群居假说。

群居的好处之一是能在和其他群居捕食者,如美洲狮和恐狼的竞争中占得优势。很多群居社会性动物都存在雌雄异态,但剑齿虎不是这样。雌性和雄性剑齿虎的犬齿长度相仿,这提示剑齿虎的群居社会结构可能更类似于现代的狼而非狮子。这也提示剑齿虎可能和豺一样是一夫一妻制,而不像狮子的一夫多妻制。

Smilodon /ˈsmaɪlədɒn/, is an extinct genus of machairodont felid. It is perhaps the best known saber-toothed cat and lived in North during the Pleistocene epoch (2.5 mya–10,000 years ago). One of the largest collections of its fossils has been obtained from the La Brea Tar Pits. Three species of the genus are known; they vary in size and build. Overall, Smilodon was more robustly built than any modern cat, with particularly well-developed forelimbs and exceptionally long upper canines. Its jaw had a bigger gape than modern cats and its upper canines were slender and fragile, being adapted for precision killing. These attributes made Smilodon a specialized hunter of large herbivores, such as bison and camels. Smilodon likely lived in closed habitats, such as forests and bush, which would have provided cover for ambushing prey. Its reliance on large animals may have been the cause of its extinction. Scientists debate over whether Smilodon was a social animal. Comparison of predator responses to distress calls and the prevalence of healed injuries suggest that it was social, while its small brain size and vegetated habitat suggest it was more solitary. Some fossils show signs of ankylosing spondylitis, trauma and arthritis. Smilodon went extinct 10,000 years ago.Tiger: (also represents your sabertooth tiger) To see a tiger in your dream, symbolizes repressed feelings or emotions that frighten you. Alternatively, the tiger represents female sexuality, aggression, and seduction. If the tiger is in a cage, then it suggests that those repressed feelings/emotions are on the verge of surfacing. White Tiger; according to Chinese astrology, the white tiger carries yin energy. This animal has always represented the admirable qualities of courage and patience. After all, the tiger must stalk its prey secretly and steadily in order to avoid scaring away its dinner. Tigers know when to lay low, but they can also spring into action when it's beneficial to reveal themselves.To dream that you are attacked by a tiger, signifies overwhelming gloom and disappointing failures. You may find yourself distressed and tormented by rivals. To dream that you ward off or kill a tiger, signifies that you will be exceedingly successful in all your endeavors. It is an indication of your good health, vitality, and vigor.TRADITIONAL CHINESE MEDICINE AND TIGERS For more than 1,000 years the use of tiger parts has been included in the traditional Chinese medicine regimen. Because of the tiger’s strength and mythical power, the Chinese culture provide rather than cure.The tiger has medicinal qualities, which helps treat chronic ailments, cure disease and replenish the body’s essential energy.Endangered tiger parts such as bones, eyes, whiskers and teeth are used to treat ailments and disease ranging from insomnia and malaria, to meningitis and bad skin. Chinese texts state that the active ingredients in tiger bone; calcium and protein, which help promote healing, have anti-inflammatory properties. Western medical experts tend to discount all claims of any curative power in tiger bone, as they do the rhinoceros horn, another popular Chinese medicine. And, it is well known that aspirin contains similar properties and produces the many of the same results as tiger prescriptions in patients Despite this, in Hong Kong, China, Taiwan, South Korea, Vietnam and in Chinatowns across Europe and North America, Chinese medicine stores do a steady trade in tiger wines, powder, tiger balms and tiger pills. Many Asian communities believe that tiger bone, in powdered form or prepared as, “tiger wine,” soothes rheumatic pain and cures ulcers, malaria and burns. These derivatives make international trade and consumption possible in the wake of the, Convention on the International Trade in Endangered Species (CITES) treaty because they are not easily recognizable as tiger parts. In recent years there has also been a resurgence of interest in traditional values and cures derived from nature in Chinese culture. Thus, the use of endangered tiger parts for medicinal properties is seen as a status symbol, a way to retain customs amid rapid change and as an alternative to the shortcomings of western medicine. The Chinese culture believes that nearly all parts of the tiger can be used to derive some medicinal cure for any number of ailments. Here are some examples of how tiger parts and their derivatives are used in traditional Chinese medicine and causing the tiger to be a critically endangered species: Tiger claws: used as a sedative for insomnia

Teeth: used to treat fever Fat: used to treat leprosy and rheumatism Nose leather: used to treat superficial wounds such as bites Tiger bone: used as an anti-inflammatory drug to treat rheumatism and arthritis, general weakness, headaches, stiffness or paralysis in lower back and legs and dysentery. Eyeballs: used to treat epilepsy and malaria Tail: used to treat skin diseases Bile: used to treat convulsions in children associated with meningitis Whiskers: used to treat toothaches Brain: used to treat laziness and pimples Penis: used in love potions such as tiger soup, as an aphrodisiac

Dung or feces: used to treat boils, hemorrhoids and cure alcoholism Fortunately, there are viable natural alternatives for those seeking traditional Chinese medicines to treat ailments and disease without using tiger derivatives.
