Are humans predators?
Predators that exert a top-down control on organisms in their community are often considered keystone species. Humans are not considered apex predators because their diets are typically diverse, although human trophic levels increase with consumption of meat.
What animals are cowards?
Hyenas. A hyena call bears an uncanny resemblance to a human laugh. Hyenas are also scavengers, which led people to portray them as cowards who would rather steal meals from more successful predators than hunt or kill their prey themselves.
Why do penguins have no fear of humans?
Penguins have no special fear of humans and will often approach groups of people. This is probably because penguins have no land predators in Antarctica or the nearby offshore islands. Typically, penguins do not approach closer than around 9 feet (3 meters), at which point they appear to become nervous.

Is there any land in Antarctica?
There are few frontiers in the world that can still be said to be unexplored. One of these terra incognita is the land beneath Antarctica’s ice sheets. Buried under kilometres of ice is a fascinating realm of canyons, waterways and lakes, which is only now being mapped in detail.
Does Antarctica have dirt?
Soils in Antarctica are nearly two-dimensional habitats, with most biological activity limited to the top four or five inches by the permanently frozen ground below. Half of the soils in the Dry Valleys have subsurface ice, either as buried massive ice or as ice-cemented soil (permafrost).
What is the temperature in Antarctica?
The mean annual temperature of the interior is −57 °C (−70.6 °F). The coast is warmer; on the coast Antarctic average temperatures are around −10 °C (14.0 °F) (in the warmest parts of Antarctica) and in the elevated inland they average about −55 °C (−67.0 °F) in Vostok.
Who lives in the Antarctic?
So what does live in Antarctica? Antarctica’s sub-zero temperatures aren’t only inhospitable to humans, but most other mammals as well. While penguins, seals and whales are the best known residents of Antarctica, they are seabirds and marine mammals.
