However, critics note that stripes do not work on lions because they frequently prey on zebras, though they may work on smaller predators, and zebras are not slow-moving enough to need to ward off threats. In addition, zebras do not possess adequate defenses to back up the warning pattern. [61]
Ever wondered why zebras have stripes? Well, the researchers behind a new study think they have a pretty good answer to that question. WMAQ reports "California scientists say the animal's black ...
Over the last 20 years, the proportion of zebras killed by lions dropped from 67 per cent to 42 per cent in the area, while the number of buffalo kills jumped from 0 per cent to 42 per cent ...
Warning calls given by birds such as the Eurasian jay are similarly honest signals, benefiting both predator and prey: the predator is informed that it has been detected and might as well save time and energy by giving up the chase, while the prey is protected from attack.
Why do zebras have stripes? The answer to that question, which scientists have wrestled with for over a century, may be most related to temperature. It was previously thought that the stripes ...
A wide range of animals, e.g. lizards, birds, rodents, and sharks, behave as if dead as an anti-predator adaptation, as predators usually take only live prey. [ 15 ] In beetles, artificial selection experiments have shown that there is heritable variation for length of death-feigning.
Get more zebras in the gallery below: Keep in mind, though, that where zebras live it has an affect on their stripes. Those in warmer climates have more stripes -- which is great for the ...
Zebras have a less efficient digestive system than ruminants but food passage is twice as fast. [15] Thus, zebras are less selective in foraging, but they do spend much time eating. The zebra is a pioneer grazer and prepares the way for more specialised grazers such as blue wildebeests and Thomson's gazelles. [9] Lions feeding on a zebra
