Non Aggressive Red tailed hawk
The Red-tailed Hawk is carnivorous, and an opportunistic feeder. Its diet is mainly small mammals, but it also includes birds and reptiles. Prey varies with regional and seasonal availability, but usually centers on rodents. Additional prey (listed by descending likelihood of predation) include lagomorphs, shrews, bats, snakes, waterfowl, fish, crustaceans and insects.
Wild beast
The ungainly gnu earned the Afrikaans name wildebeest, or "wild beast," for the menacing appearance presented by its large head, shaggy mane, pointed beard, and sharp, curved horns. In fact, the wildebeest is better described as a reliable source of food for the truly menacing predators of the African savanna: lions, cheetahs, wild dogs, and hyenas.
Their habitat comprises the grassy plains and open woodlands of central, southern, and eastern Africa, particularly the Serengeti in Tanzania and Kenya. They travel in large herds and are active day and night, grazing constantly.

Red-eyed Tree Frog
The Red-eyed Tree Frog (Agalychnis callidryas) is a small-sized tree frog, reaching lengths of about 5 to 7 centimeters (3 inches), native to Neotropical rainforests in Central America. They are not poisonous and rely on camouflage to protect them. During the day, they remain motionless with their colorful parts hidden. Thus, they appear almost completely green, and well hidden among the foliage.

Most beautiful eagle
The sea eagle is white on the head, rump and underparts and dark grey on the back and wings. In flight the black flight feathers on the wings are easily seen when the bird is viewed from below. The large, hooked bill is grey with a darker tip, and the eye is dark brown. The legs and feet are cream-white, with long black talons (claws). Young Sea-eagles are brown when juveniles then gradually come to resemble adults, acquiring the complete adult plumage by their fourth year. Birds form permanent pairs that inhabit territories throughout the year. Their loud "goose-like" honking call is a familiar sound, particularly during the breeding season. They chose the tallest tree to nest, and even sometimes man-made pylons.

Intelligent - African Gray Parrot
Irene Pepperberg's extensive research with captive African greys, especially the one known as Alex, have provided evidence that these parrots are capable of associating human words with their meanings, at least to some extent, though these conclusions are disputed. Ambitious claims of language use have been made for another African grey, N'kisi, who has a vocabulary of around a thousand words and speaks in sentences.
Fox Squirrels
Fox Squirrels are strictly diurnal, non-territorial, and spend more of their time on the ground than most other tree squirrels. They are still, however, agile climbers. They construct two types of homes called "dreys", depending on the season. Summer dreys are often little more than platforms of sticks high in the branches of trees, while winter dens are usually hollowed out of tree trunks by a succession of occupants over as many as 30 years. Cohabitation of these dens is not uncommon, particularly among breeding pairs.

Geographic cone snail
The incredibly toxic venom of the geographic cone snail has to be strong enough to paralyze instantly. Otherwise, the fish it preys on would swim away to die, and the slow-moving gastropod would have nothing for its efforts.
Indigenous to the reefs of the Indo-Pacific, geographic cones grow to about 6 inches (15 centimeters) in length and have intricately patterned brown-and-white shells highly prized by shell collectors.
The geographic cone is the most venomous of the 500 known cone snail species, and several human deaths have been attributed to them. Their venom, a complex concoction of hundreds of different toxins, is delivered via a harpoonlike tooth propelled from an extendable

Milk snakes don't drink milk
Like other members of the king snake family, the milk snakes sometimes eat other snakes, and do have at least some immunity to their venom.

Burying beetles
The prospective parents begin to dig a hole below the carcass. While doing so, the beetles cover the animal with antibacterial and antifungal oral and anal secretions, slowing the decay of the carcass and preventing the smell of rotting flesh from attracting competition. The carcass is formed into a ball and the fur or feathers stripped away and used to line and reinforce the crypt, where the carcass will remain until the flesh has been completely consumed. The burial process can take around 8 hours. Several pairs of beetles may cooperate to bury large carcasses and then raise their broods communally.

Largest and oldest known chestnut tree in the world
Fearless Hood Mockingbird
The birds have a strong social structure organized into family groups. Highly territorial, these groups will cooperatively hunt within their area as well as defend it against other groups. Lower-ranking members of the group will assist in caring for the young.The bird is considered to be vulnerable in the wild by BirdLife International due mainly to its limited area.

Worlds largest fish
Sea Dragon
The Leafy Sea Dragon has a long, pipe-like snout that it uses to feed. It primarily eats crustaceans including plankton and mysids, but its diet also includes shrimp and other small fish. It catches its prey using its camouflage ability. Leafy sea dragons oddly enough do not have teeth, which is rare amongst animals that eat small fish and shrimp.
The Leafy Sea Dragon is a cousin of the pipefish and belongs to the family Syngnathidae, along with the seahorse. The Leafy Sea Dragon differs from the seahorse in its appearance, form of locomotion, and the Leafy Sea Dragon's inability to coil or grasp things with its tail. A related species is the weedy sea dragon, which is multi-coloured and grows weed-like fins and can be much smaller than the leafy sea dragon. In the November 2006 issue of National Geographic magazine, marine biologist Greg Rouse is reported as investigating the DNA variation of the two sea dragon species across their ranges.

Ant mimicking spiders
Spiders in this genus are commonly called "antmimicking spiders", although there are many other spiders that mimic ants. Colors vary from black to yellow, depending on the mimicked ant species. One African species was observed to mimick one species when immature, and another as an adult
