North Pacific Right Whale

North Pacific Right Whale 

North Pacific Right Whale is the 2nd largest animal in the world before blue whale. It live in north pacific that's why it is called The North Pacific Right Whale.

Taxonomy

Until recently, all right whales of the genus Eubalaena were considered a single species—E. glacialis. In 2000, genetic studies of right whales from the different ocean basins led scientists to conclude that the populations in the North Atlantic, North Pacific and Southern Hemisphere constitute three distinct species which they named: the North Atlantic right whale (Eubalaena glacialis), the North Pacific right whale (Eubalaena japonica) and the Southern right whale (Eubalaena australis).

Ecology and behavior

Like other right whale species, the North Pacific right whale feeds by skimming water continuously while swimming, in contrast to balaenopterid whales such as the blue and humpback whales which engulf prey in rapid lunges. Right whales do not have pleated throats. Instead they have very large heads and mouths that allows them to swim with their mouths open, the water with the copepods flowing in, then flowing sideways through the right whale's very long, very fine baleen trapping the copepods, and then out over their large lower lips.

Behavior

There have been some noteworthy non-visual observations. NMFS biologists deployed various passive acoustic listening devices in the Bering Sea and Gulf of Alaska, recording at least 3,600 North Pacific right whale calls between 2000 and 2006.

Harpy Eagle

Harpy Eagle 

Harpy Eagle is the most strongest bird in America's rain forest. It is most strongest raptor in North America. It has sharp talons. It is 1 m long.

Taxonomy

The only member of the genus Harpia, the Harpy Eagle is most closely related to theCrested Eagle (Morphnus guianensis) and the New Guinea Harpy Eagle (Harpyopsis novaeguineae), the three composing the subfamily Harpiinae within the large family Accipitridae. Previously thought to be related, the Philippine Eagle has been shown by analysis of DNA to belong elsewhere in the raptor family as it is related to the Circaetinae.

Distribution and habitat

The Harpy Eagle inhabits tropical lowland rainforests and may occur within such areas from the canopy to the emergent vegetation. They typically occur below an elevation of 900 m (3,000 ft) but have been recorded at elevations of up to 2,000 m (6,600 ft).

Location

Feeding

At several nest in Guyana, monkeys made up approximately 37% of the prey remains found at the nests. Similarly, cebid monkeys made up 35% of the remains found at 10 nest in Amazonian Ecuador. Other partially arboreal mammals are also predated given the opportunity, including porcupines, squirrels, opossums, anteaters, and even relatively large carnivores such as kinkajous, coatis and tayras. In the Pantanal, a pair of nesting eagles preyed largely on the porcupine Coendou prehensilis and on the agouti Dasyprocta azarae.

Bull shark

Bull shark

Bull shark is the 4th dangerous in the world . It lives in fresh water and saltwater. It is perfect killing machine . It's bite ever recorded in 919 psi.

Etymology

In India, the bull shark may be confused with the Sundarbans or Ganges shark. In Africa, it is also commonly called the Zambezi River shark or just Zambi. Its wide range and diverse habitats result in many other local names, including Ganges River shark, Fitzroy Creek whaler, van Rooyen’s shark, Lake Nicaragua shark.

Diagram

Behavior

Bull sharks are able to regulate themselves to live in either fresh water or salt water. It is possible for the bull shark to live in fresh water for its entire life, but it has been observed that this does not happen for certain reasons, mostly due to reproduction. Young bull sharks will leave the brackish water in which they are born and move out into the sea in order to breed with bull sharks of the other sex. While theoretically, it may be possible for bull sharks to live in purely freshwater, it was observed that the bull sharks that were being experimented on had died within four years.

Green mamba

Green mamba

Green mamba is the 2nd most venomous snake in Africa . It has long fangs. It's mouth is white not like black mamba . It eats rats and rabbits. It gas enemies like eagle .

Etymology

The generic name, Dendroaspis, is derived from Ancient Greek words – Dendro, which means "tree",and aspis (ασπίς) or "asp", which' is understood to mean "shield", but it also designate "cobra" or simply "snake". In old text, aspis or asp was used to refer to Naja haje (in reference with the hood, like a shield). Thus, "Dendroaspis" literally means tree snake, which refers to the arboreal nature of most of the species within the genus

Biology

Male eastern green mambas are generally slightly larger than females.The species has two enlarged venom fangs fixed to the front of the mouth and solid teeth in both jaws. It has very smooth scales, is thin and elegant with a very distinctive head that is long and rectangular and they have a long thin tail. Their eyes are medium in size with round pupils. 

Behavior and Diet

It will avoid confrontation with humans or other potential predators when possible, and will rather rely on its camouflage, or flee, than alert a potential threat of its presence. They are fast snakes, capable of moving 7 mph. They don't always strike, but under continuous harassment and provocation and especially if cornered, they may suddenly become very ferocious and strike repeatedly in quick succession.

Vampire bats

Vampire bats

Vampire bats is an only mammals who sucks blood.. It sucks blood of cows, pigs, boar and even human. It's live in North America.

Anatomy and Physiology

A vampire bat generally has small ears and a short tail. Its front teeth are specialized for cutting and the back teeth are much smaller than in other bats. The inferior colliculus, the part of the bat's brain that processes sound, is well adapted to detecting the regular breathing sounds of sleeping animals that serve as its main food source.

Ecology and life cycle

Vampire bats are believed to be the only species of bats in the world to "adopt" another young bat if something happens to the bat's mother. Vampire bats also share a strong family bond with members of the colony, which is believed to be why they are the only bats to take up this adoption characteristic. Another unique adaptation of vampire bats is the sharing of food.

Feeding

The common vampire bat feeds mostly on the blood of mammals (occasionally including humans), whereas both the hairy-legged vampire bat and white-winged vampire bat feed on the blood of birds. Once the common vampire bat locates a host, such as a sleeping mammal, it lands and approaches it on the ground. It then likely uses thermoception to identify a warm spot on the skin to bite.

Black bear

Black bear

Black bear is a omnivores animal. It is the 3rd strongest bear in the world before grizzly and polar bear. It has sharp claws and they can bring dead even human beings. 

Taxonomy and evolution

A small primitive bear called Ursus abstrusus is the oldest known North American fossil member of the genus Ursus, dated to 4.95 mya. This suggests that U. abstrusus may be the direct ancestor of the American black bear, which evolved in North America.

Current range and population

Black bears currently inhabit much of their original Canadian range, though they do not occur in the southern farmlands of Alberta, Saskatchewan, and Manitoba. They have been extinct in Prince Edward Island since 1937. The total Canadian black bear population is between 396,000 and 476,000.

Habitat

The adaptation to woodlands and thick vegetation in this species may have originally been due to the black bear having evolved alongside larger, more aggressive bear species, such as the extinct short-faced bear and the still living grizzly bear, that monopolized more open habitats  and the historic presence of larger predators such as Smilodon and the American lion that could have preyed on black bears. Although found in the largest numbers in wild, undisturbed areas and rural regions, black bears can adapt to surviving in some numbers in peri-urban regions as long as they contain easily accessible foods and some vegetative coverage.

Skull

Location

Behavior

American black bears tend to be territorial and non-gregarious in nature. However, at abundant food sources (i.e. spawning salmon or garbage dumps) black bears may congregate and dominance hierarchies form, with the largest, most powerful males dominating the most fruitful feeding spots. They mark their territories by rubbing their bodies against trees and clawing at the bark. Annual ranges held by mature male black bears tend to be very large but there is some variation.  

Hibernation

Black bears enter their dens in October and November. Prior to that time, they can put on up to 30 pounds of body fat to get them through the seven months during which they fast. Hibernation in black bears typically lasts 3–5 months.During this time, their heart rate drops from 40–50 beats per minute to 8 beats per minute.
