Animal Adaptation The animals have to compete for food so many animals must adapt by learning to eat a particular food eaten by few animals or no other animal. Toucans for example have adapted by developing a long, large bill. This allow this bird to reach fruit on branches that are too small to support the bird’s weight and to cut the fruit from the tree. Another good example is the sloth. The sloth uses behavioral adaption and camouflage to survive in the rainforest.
Channa Argus, commonly known as the northern snakehead, is one of the many invasive species around the world. This species is a top level predator and was introduced to several American states in 2002, but its natural habitat is based in southern and eastern Asia. Northern snakeheads were transported to the waters of America by being sold from pet stores and live food fish markets, followed by being released into the wild. The northern snakehead fish threatens and competes for the native species’ resources and habitat. The northern snakehead preys on zooplankton, smaller fish, fish larvae, crustaceans, frogs, insects, small reptiles, and even small mammals and birds.
They have beaks of the crushing category, which helps them on breaking the seeds. The small ground finch has a small beak which is suited for eating tiny seeds. It searches for food on the ground for the seeds of plants such as the Galapagos carpetweed. This species is wide spread throughout the archipelago. The large ground finch has a huge beak.
It has aboreal living style and omnivore and eat every type of food as grain, fruit etc.Rattus rattus (black rat) is omnivores. They are infectious pests and eat bird and some arthropods they destroy many agricultural crops. They can cause Yersinia pestis that result in bubonic plague (Amori et al).it caused serious plague in Europe in medieval era and its movements produced serious
The predator, which is an eagle, the rats hide in mud; The eagle is able to see the white rats and eats them, that is an advantage to brown rats. Disruptive selection means that natural selection is in favor of the average general individual in a group of organisms. An example of disruptive selection can be where there are white and black rabbits. Their offspring are grey, in the area where they live there are white and black rocks which they use to hide from their predators, this only benefits white and black rabbits. However, grey rabbits will have a greater chance to get eaten.
It bthe type of parasitic infection by tapeworm. This is one of common disease occur in most areas of the world. It also require two hosts, definitive host-carnivores and intermediate hosts- sheep and cattle. Humans are accidental hosts, because they are a dead end of this infection. Humans are infected by handling soil, dirt or animal hair that contains eggs of this tapeworm..In humans they are localized in the liver in most of the cases and in other organs of bodies such as spleen, brain heart and kidney.
The bamboo is 99% panda’s chief source of food (Nowak & Paradiso, 1983). It consume almost 15 kilograms of bamboo (roots, shoots, leaves) a day. Wild pandas feed in almost 25 known species of bamboo. Yet the panda has a gastrointestinal tract that is found in carnivores and lacks of modification observed from most of herbivores that promote increase digest retention to facilitate microbial fermentation of ingested plant materials (Schaller et al., 1985) Despite of widely known bamboo-eaters, these mammals eat other herbivorous food like gentians, irises, crocuses, Chinese vines and tuft grasses ( Pen Hung-Shou,1943). Reports that that these animals raid bee hives for honey (Perry, 1969).
These tunnels weaken the wood and potentially damage the wood that keeps the house standing. 3. ODOROUS HOUSE ANTS- This ant gets its name from the strong, rotten coconut-like smells it gives off when crushed and the fact that they commonly nest in or around houses.
