American Alligator

                                         

Anatomy

The American Alligator has a large, slightly rounded body, with thick limbs, a broad head, and a very powerful tail. They generally have an olive, brown, gray or nearly black color with a creamy white underside. Algae-laden waters produce greener skin, while tannic acid from overhanging trees can produce often darker skin. Adult male alligators are typically 11.2 to 14.5 ft (3.4 to 4.4 m) in length, while adult females average 8.2 to 9.8 ft (2.5 to 3.0 m). One American Alligator allegedly reached a length of 19 feet 2 inches (5.8 m), which would have made it the largest ever recorded, but this has never been verified or even supported by reliable information and is considered highly unlikely by experts. The general average length for an adult male alligator is 9 to 11 ft (2.7 to 3.4 m). The tail, which accounts for half of the alligator's total length, is primarily used for aquatic propulsion. The tail can also be used as a weapon of defense when an alligator feels threatened. Alligators travel very quickly in water and while they are generally slow-moving on land, alligators can lunge short distances very quickly. They have five claws on each front foot and four on each rear foot. American Alligators have the strongest bite of any living animal, measured at up to 9,452 newtons (2,125 lb_f) in laboratory conditions. Some alligators are missing an inhibited gene for melanin, which makes them albino. These alligators are extremely rare and practically impossible to find in the wild. They could survive only in captivity. Like all albino animals, they are very vulnerable to the sun and predators.

Diet

Alligators eat fish, birds, turtles, snakes, mammals, and amphibians. Hatchlings, however, are restricted to smaller prey items like invertebrates. Insects and larvae, snails, spiders, and worms make-up a big portion of a hatchling's diet. They will also eat small fish at any opportunity. As they grow, they gradually move onto larger fish, mollusks, frogs and small mammals like rats, and mice. Some adult alligators take a larger variety of prey ranging from a snake or turtle to a bird and moderate sized mammals like a raccoon or deer.

 American Crocodile

       

The American crocodile is considered an endangered species in nearly all parts of its North, Central, and South American range. Survey data, except in the United States, is poor or nonexistent, but conservationists agree that illegal hunting and habitat depletion has reduced populations of this wide-ranging reptile to critical levels.

A small, remnant population lives in southern Florida, but most are found in southern Mexico, Central America, the Caribbean, and northern South America. Their habitat of choice is the fresh or brackish water of river estuaries, coastal lagoons, and mangrove swamps.

A prehistoric-looking creature, it is distinguishable from its cousin, the American alligator, by its longer, thinner snout, its lighter color, and two long teeth on the lower jaw that are visible when its mouth is closed.

This species is among the largest of the world's crocodiles, with Central and South American males reaching lengths of up to 20 feet (6.1 meters). Males in the U.S. population rarely exceed 13 feet (4 meters), however.

Their diet consists mainly of small mammals, birds, fish, crabs, insects, snails, frogs, and occasionally carrion. They have been known to attack people, but are far more likely to flee at the sight of humans.

 
Florida Panther

        

The Florida panther is a critically endangered representative of cougar (Puma concolor) that lives in the low tides, palm forests and swamps of southern Florida in the United States. Its current taxonomic status (Puma concolor coryi or Puma concolor couguar) is unresolved. The Florida Panther is also known as the cougar, mountain lion, puma, and catamount.

 Bobcat

                

Bobcats are elusive and nocturnal, so they are rarely spotted by humans. Although they are seldom seen, they roam throughout much of North America and adapt well to such diverse habitats as forests, swamps, deserts, and even suburban areas.

Bobcats, sometimes called wildcats, are roughly twice as big as the average housecat. They have long legs, large paws, and tufted ears similar to those of their larger relative, the Canada lynx. Most bobcats are brown or brownish red with a white underbelly and short, black-tipped tail. The cat is named for its tail, which appears to be cut or "bobbed."

Fierce hunters, bobcats can kill prey much bigger than themselves, but usually eat rabbits, birds, mice, squirrels, and other smaller game. The bobcat hunts by stealth, but delivers a deathblow with a leaping pounce that can cover 10 feet (3 meters).

Bobcats are solitary animals. Females choose a secluded den to raise a litter of one to six young kittens, which will remain with their mother for 9 to 12 months. During this time they will learn to hunt before setting out on their own.

 The American Black Bear

                       

Anatomy

The American Black Bear usually ranges in length from 150 to 180 centimeters (5 to 6 ft) and typically stands about 76 to 91 centimeters (2.5 to 3 ft) at the shoulder. Standing up on its hind feet, a Black Bear can be up to 2.12 meters (7 ft) tall. Females are 33% smaller than males, an example of sexual dimorphism. Females weigh between 40 and 180 kilograms (90 and 400 lb); males usually weigh between 70 and 275 kilograms (155 and 600 lb). Adult black bears can reach 300 kilograms (660 lb), but exceptionally large males have been recorded from the wild at up to 240 centimeters (95 in) long and at least 365 kilograms (800 lb). The biggest American Black Bear ever recorded was a male from North Carolina that weighed 400 kilograms (880 lb). At the other extreme, very small adult bears can weigh as little as 39 kilograms (85 lb) in females and 47 kilograms (103 lb) in males. Cubs usually weigh 200 to 450 grams (7 to 16 oz) at birth. The adult has small eyes, rounded ears, a long snout, a large body, and a short tail. It has an excellent sense of smell. Though they generally have shaggy black hair, the coat can vary in color from white through chocolate-brown, cinnamon-brown, and blonde (found mostly west of the Mississippi River), to black in the east (the same is generally true in Canada, the border being between Manitoba and Ontario). They occasionally have a slight V-shaped white chest blaze. The tail is 12.12 centimeters (4.8 in) long.

Although Black Bears can stand and walk on their hind legs it is more normal for them to walk on all fours. When they do stand, it is usually to get a better scent or to look at something. Their characteristic shuffling gait results from their plantigrade (flat-footed) walk, with the hind legs slightly longer than the forelegs. Another reason for the apparent shuffle is that they commonly walk with a pacing gait. Unlike many quadrupeds, the legs on one side move together instead of alternating, much like a pacer horse. Each paw has five long, strong claws used for tearing, digging, and climbing. Though relatively less powerful than a grizzly bear, black bears are still enormously powerful. In one account, a 55-kilogram bear cub lifted off a 140 to 146-kilogram rock "back-handed". When necessary, they can run at speeds up to 48 km/h (30 mi/h) and are good swimmers. The ears of a black bear are larger and more erect than those of the brown bear, and it lacks a prominent shoulder hump.

<sup>DIET

Black bears are omnivores whose diet includes plants, meat, and insects. Their diet typically consists of about 10-15% animal matter. They are apex predators in North America, with the exception of areas where they coexist with the brown bear. The black bear eats a wide variety of foods, mainly herbs, nuts and berries. In the state of Washington and other parts of the Pacific Northwest, black bears eat a large amount of skunk cabbage, horsetail and tree bark during the spring. They also commonly feed on spring acorns in Massachusetts.</sup>

^{Black bears feed on carrion and insects (mainly for the larvae) such as carpenter ants, yellow jackets, bees, wasps and termites. They raid beehives for both honey and bee larvae as both are easy sources of carbohydrates (honey) and protein (larvae.) They also kill and eat small mammals (such as rodents) and ungulates, mostly the young. In Michigan and the state of New York, black bears prey on white-tailed deer fawns. In addition they have been recorded preying on elk calves in Idaho and moose calves in Alaska. The taking of moose calves (their largest regular prey) can be hazardous, especially in contention with the large, aggressive mothers.}

^{Additionally, black bears will eat salmon, suckers, American alligator eggs, crayfish, and trout and will seek out food within orchards, beehives, and agricultural croplands. They may frequently raid garbage dumps, campsites, or appropriate food from the trash bins of businesses or private homes.}

<sup>Black bears often drag their prey to cover, preferring to feed in seclusion and frequently begin feeding on the udder of lactating females, but generally prefer meat from the viscera. The skin of large prey is stripped back and turned inside out with the skeleton usually left largely intact. Unlike wolves and coyotes, black bears rarely scatter the remains of their kills. Vegetation are found the carcass is usually matted down by black bears and their droppings are frequently found nearby. Black bears may attempt to cover remains of larger carcasses, though they do not do so with the same frequency as cougars and grizzly bears.  

Burmese Python

   

Burmese pythons, with their beautifully patterned skin, rapid growth rate, and generally docile disposition, may be best known as the large snake of choice among reptile owners. Unfortunately these potentially huge constrictors are often poorly cared for and are frequently released into the wild. Attacks on handlers, sometimes deadly, are not uncommon.

Native to the jungles and grassy marshes of Southeast Asia, Burmese pythons are among the largest snakes on Earth. They are capable of reaching 23 feet (7 meters) or more in length and weighing up to 200 pounds (90 kilograms) with a girth as big as a telephone pole. When young, they will spend much of their time in the trees. However, as they mature and their size and weight make tree climbing unwieldy, they transition to mainly ground-dwelling. They are also excellent swimmers, and can stay submerged for up to 30 minutes before surfacing for air.

Burmese pythons are carnivores, surviving primarily on small mammals and birds. They have poor eyesight, and stalk prey using chemical receptors in their tongues and heat-sensors along the jaws. They kill by constriction, grasping a victim with their sharp teeth, coiling their bodies around the animal, and squeezing until it suffocates. They have stretchy ligaments in their jaws that allow them to swallow all their food whole.</sup>

 White-Tailed Deer

         

White-tailed deer, the smallest members of the North American deer family, are found from southern Canada to South America. In the heat of summer they typically inhabit fields and meadows using clumps of broad-leaved and coniferous forests for shade. During the winter they generally keep to forests, preferring coniferous stands that provide shelter from the harsh elements.

Adult white-tails have reddish-brown coats in summer which fade to a duller grayish-brown in winter. Male deer, called bucks, are easily recognizable in the summer and fall by their prominent set of antlers, which are grown annually and fall off in the winter. Only the bucks grow antlers, which bear a number of tines, or sharp points. During the mating season, also called the rut, bucks fight over territory by using their antlers in sparring matches.

Female deer, called does, give birth to one to three young at a time, usually in May or June and after a gestation period of seven months. Young deer, called fawns, wear a reddish-brown coat with white spots that helps them blend in with the forest.

White-tailed deer are herbivores, leisurely grazing on most available plant foods. Their stomachs allow them to digest a varied diet, including leaves, twigs, fruits and nuts, grass, corn, alfalfa, and even lichens and other fungi. Occasionally venturing out in the daylight hours, white-tailed deer are primarily nocturnal or crepuscular, browsing mainly at dawn and dusk.
 

Raccoon
               

Bandit-masked raccoons are a familiar sight just about everywhere, because they will eat just about anything. These ubiquitous mammals are found in forests, marshes, prairies, and even in cities. They are adaptable, and use their dexterous front paws and long fingers to find and feast on a wide variety of fare.

In the natural world, raccoons snare a lot of their meals in the water. These nocturnal foragers use lightning-quick paws to grab crayfish, frogs, and other aquatic creatures. On land, they pluck mice and insects from their hidey-holes and raid nests for tasty eggs.

Raccoons also eat fruit and plants—including those grown in human gardens and farms. They will even open garbage cans to dine on the contents.

SKUNK

              


Skunks are legendary for their powerful predator-deterrent—a hard-to-remove, horrible-smelling spray. A skunk's spray is an oily liquid produced by glands under its large tail. To employ this scent bomb, a skunk turns around and blasts its foe with a foul mist that can travel as far as ten feet (three meters).

Skunk spray causes no real damage to its victims, but it sure makes them uncomfortable. It can linger for many days and defy attempts to remove it. As a defensive technique, the spray is very effective. Most skunks present otherwise easy prey for larger animals, but typically these predators give them a wide berth unless little other food is available.

There are many different kinds of skunks. They vary in size (most are housecat-sized) and appear in a variety of striped, spotted, and swirled patterns—but all are a vivid black and white that makes them easily identifiable and may alert predators to their pungent potential.


Opossum

     

There are more than 60 different species of opossum, which are often called possums. The most notable is the Virginia opossum or common opossum—the only marsupial (pouched mammal) found in the United States and Canada.

A female opossum gives birth to helpless young as tiny as honeybees. Babies immediately crawl into the mother's pouch, where they continue to develop. As they get larger, they will go in and out of the pouch and sometimes ride on the mother's back as she hunts for food. Opossums may give birth to as many as 20 babies in a litter, but fewer than half of them survive. Some never even make it as far as the pouch.

Opossums are scavengers, and they often visit human homes or settlements to raid garbage cans, dumpsters, and other containers. They are attracted to carrion and can often be spotted near roadkill. Opossums also eat grass, nuts, and fruit. They will hunt mice, birds, insects, worms, snakes, and even chickens.

These animals are most famous for "playing possum." When threatened by dogs, foxes, or bobcats, opossums sometimes flop onto their sides and lie on the ground with their eyes closed or staring fixedly into space. They extend their tongues and generally appear to be dead. This ploy may put a predator off its guard and allow the opossum an opportunity to make its escape.
