Water buffalo and oxpeckers
Barnacles and whales
Orchids and trees

Sometimes when there is a niche that can be filled by an adaptation, evolution favours the selection of individuals with such traits. At the same time, when an organism is very resilient, it does not require further evolution, if it can tolerate almost any extreme environment. Which organism below can live both at the coldest temperatures of the poles and the hottest temperatures of the deserts, and has evolved very little in the last 500 million years?
A tartigrade
A spadefoot frog
A camel
A polar bear
An animal is considered feral if it is brought to a location as a domestic pet, and then manages to escape into the wild. If there are no niches for the organism to fill, it will die off. If there are many niches for it to fit, it will increase in number. What feral animal was introduced to Australia in the late 1800s (with roughly 100 of them), and by 1960, it was estimated to have established a population of 287 million?
Red foxes
Coyotes
Mice
Rabbits
