Coyotes are considered to be the most invasive species in North America. They dangerously wander around towns when food is scare. Coyotes are major predators to cows, sheep, other livestock, and pets. Each and every year, coyotes kill thousands of species in suburban and rural areas. The government continuously has to spend money on agriculture, poisoning, trapping, and killing coyotes to stop this.

Coyotes are close members of the dog family. They form packs and have strong family groups. They are fast animals and can run 40 miles per hour. In the cols seasons, such as fall and winter, packs are mostly formed especially for hunting. Many species in North America are prey to coyote and suffer everyday. Such species are, rabbits, rodent, fish, frogs, and deer.

During the spring, female coyotes give birth to liters of three to twelve pups. Male and female coyotes are highly protective of their offspring, which includes feeding them and protecting their land. Coyote pups are able to hunt on their own in the fall after their birth in the spring. Similar to wolves, coyotes are smaller in size.

The Bluefin Tuna are considered to be the most endangered species in aquatic life zones. These species are constantly being over fished by numerous amounts of fishermen. Since the bluefin tuna swim in large schools of fish, they capture the attention of fishermen making it easier to catch them. Also, the bluefin tuna make excellent meals in restaurants and are highly utilized by commercial fishing companies.

Being one of the largest bony fishes in the sea, the bluefin tuna can grow up to 3 meters in length. The bluefin tuna are great swimmers and migrate often. They can also weigh up to 1000 pounds. 

A female bluefin tuna can produce between 20 to 30 million eggs. The bluefin tuna eat smaller fish, such as mackerel, herring, whiting, flying fish, and mullet. Besides consuming fish, the bluefin tuna eats squid, eels, and even crustaceans.

The white tailed deer are considered to be keystone species because they alter the forests composition and structure. By keeping the forests healthy, many of the other animals are able to live sustainably in their habitats. They eat a variety of vegetation depending on whats available for them. Since the white tailed deer eat a variety of vegetation, they will eat the excess growth from plants that is not needed.

White tale deer are specialist species. Their habitat can contain dense thickets and biomes that has an abundance of trees, bushes, and shrubs. White tailed deers live in the deciduous forests and coniferous forests.

Mating season occurs in November and December. Before giving birth, femal white tail deer are overprotective of their territory. They often stay in groups of deer called herds.

The cheetahs should be considered the coolest predator adaptation because they are the fastest land animal in the world. Cheetahs are so fast that they run between 60 to 70 miles per hour. To search for prey, cheetahs utilize their eyesight before unleashing their speed. When cheetahs have captured their prey, they knock the prey down and nearly suffocate it.

Offspring of cheetahs consists of three cubs. The cubs spend a year learning how to hunt like their parents. Male cheetahs are dependent and live in a habitat alone. After a year, cheetahs offspring will be a true predator.

Cheetahs are found in open savannas where it is dry. The savanna contains high grasses. There is hardly ever any rain or much water. Cheetahs only need to drink every three to four days. They also are up during the daylight hours.

Zebras should be considered the coolest prey adaptation because their stripes are so distinctive and unique that it makes it challenging for predators to capture them. A zebra's stripes are a form of camouflage to help protect them from the harm of vicious species, like lions. Zebras are found in large herds, which make it harder for a predator to distinguish at least one zebra. However, if a zebra is alone, then it is easier for a predator to capture it and feed on it.

Zebras spend most of their time in the savanna. The savanna contains giant grasses and scattered trees. Zebras graze on grass and groom together primarily on a daily basis. Zebras are also herbivores.

Offspring are born any time of the year. They range from 66 to 77 pounds. After ten minutes of birth, young zebras are able to stand on their own. Also, after eleven months, young zebras can start eating grass.
