BLACK MAMBA THE TASMANIAN DEVIL STRUCTURAL AND BEHAVIOURAL ADAPTATIONS

BLACK MAMBA

KNOW THIS FIRST. The Black Mamba is the most deadly snake in the world. They grow 14 feet in length, and can travel at speeds of up to 12 mph. They have a head shaped like a coffin. THE Black Mamba is not actually black. They have a brownish-gray body with a light belly and brownish scales along its back. It gets its name from the color of the lining of its mouth, which is purple-black, and which it displays when threatened.

HABITAT The Black Mamba lives in South Africa. They like open, low habitats such as savannas, rocky places and open woodlands. They are active during the day. They often sleep in hollow trees, burrows, rock crevices, or empty termite mounds, and will come back to the same place every night.

DIET The Black Mambas feed on small mammals and birds, like voles, rats, squirrels, mice, rats, or bush babies.

STRUCTURAL ADAPTATION They have a head shaped like a coffin. They also have a very long body . It has two needle-like sharp fangs.

BEHAVIOURAL ADAPTATION Black mambas are shy and will almost always seek to escape when confronted. However, when cornered, these snakes will raise their heads, sometimes with a third of their body off the ground, spread their cobra-like neck-flap, open their black mouths and hiss. If an attacker persists, the mamba will strike not once, but repeatedly, injecting large amounts of potent neuro- and cardiotoxin with each strike.

WAIT THERE’S MORE! The Black Mambas are found in pairs or small groups. They are very nervous, and head away fast when a human approaches. When the mamba feels threatened it will raise its front and head about 3-4 feet off the ground, open its mouth, spread a flat hood, and shake its head. When they attack they will make several quick strikes, and escape as fast as they can. They can strike from 4-6 feet away.

NOW THE TASMANIAN DEVIL

Know this first. The Tasmanian devil is the world's largest carnivorous marsupial, reaching 30 inches (76 centimeters) in length and weighing up to 26 pounds (12 kilograms), although its size will vary widely depending on its specific range and the availability of food. Its oversize head houses sharp teeth and strong, muscular jaws that can deliver, pound for pound, one of the most powerful bites of any mammal.

Once abundant throughout Australia Tasmanian devils are now indigenous only to the island state of Tasmania. Their Tasmanian range encompasses the entire island, although they are partial to coastal scrublands and forests

DIET Tasmanian devils are strictly carnivorous, surviving on small prey such as snakes, birds, fish, and insects and frequently feasting communally on carrion. They are at their most rowdy when jockeying for position on a large carcass. Like other marsupials, when they are well fed, their tails swell with stored fat.

STRUCTURAL ADAPTATION These famously feisty mammals have a coat of coarse brown or black fur and a stocky profile that gives them the appearance of a baby bear. Most have a white stripe or patch on their chest and light spots on their sides or rear end. They have long front legs and shorter rear legs, giving them a lumbering, pig like gait.

BEHAVIOURAL ADAPTATION Tasmanian devils have a notoriously cantankerous disposition and will fly into a maniacal rage when threatened by a predator, fighting for a mate, or defending a meal. Early European settlers dubbed it a "devil" after witnessing such displays, which include teeth-baring, lunging, and an array of spine-chilling guttural growls.

Save them Tragically, though, a catastrophic illness discovered in the mid-1990s has killed tens of thousands of Tasmanian devils. Called devil facial tumor disease (DFTD), this rapidly spreading condition is a rare contagious cancer that causes large lumps to form around the animal's mouth and head, making it hard for it to eat. The animal eventually starves to death. Animal health experts are sequestering populations where the disease has not yet appeared and are focusing on captive breeding programs to save the species from extinction. Because of the outbreak, the Australian government has listed Tasmanian devils as vulnerable.
