You can bet that I May not be alive, but I sure as hell ain't dead inside.What's with the shouting? I ain't wishing you harm.You see, I'd try to hold your hand but I'm missing an arm.Brains are all I've eaten all week it's true,But if my heart were still beating, it would beat for you.So let me take you to Wendy's. You deserve it.Yeah, I'm a zombie, baby. Ain't nobody perfect.I'll chase you through the yard and all through the house into the dark.Oh I wanna steal your heart and eat your brains.I've never been so true, but if my heart were still beating, it would beat for you.Oh I wanna steal your heart and eat your brains.
Baby, sometimes I bite, and you can bet That I've got an appetite for human flesh.show always be near though. You'll have to accept thatWhen I nibble on your earlobe you might get infected.
Cause I fell in love with you and I'm Undead but you make me feel alive. And when I chase you through the graveyard It feels like foreplay.

If I'm lying I'm dying, and I speak trulyWhen I say I love your mind. I'll take brains over beauty.

And errbody love you, and you can sing along to this post-apocalyptic, postmortem love song.
So give me a chance, girl. You know I'll be worth it.Yeah, I'm a zombie, baby. Ain't nobody perfect.

Characteristic of a Crab

Crab



F1772 B140 - Plastic Hermit Crab, 4 3/4 inches wide

Crabs are generally covered with a thick exoskeleton, and armed with a single pair of chelae (claws). Crabs are found in all of the world's oceans, while many crabs live in fresh water and on land, particularly in tropical regions. Crabs vary in size from the pea crab, a few millimetres wide, to the Japanese spider crab, with a leg span of up to 4 metres (13 ft).
About 850 species of crab are freshwater, terrestrial or semi-terrestrial species; they are found throughout the world's tropical and semi-tropical regions. They were previously thought to be a monophyletic group, but are now believed to represent at least two distinct lineages, one in the Old World and one in the New World.
The earliest unambiguous crab fossils date from the Jurassic although Carboniferous Imocaris, known only from its carapace, may be a primitive crab. The radiation of crabs in the Cretaceous and afterward may be linked either to the break-up of Gondwana or to the concurrent radiation of bony fish, crabs' main predators.



 Sexual dimorphism

Crabs often show marked sexual dimorphism. Males often have larger claws, a tendency which is particularly pronounced in the fiddler crabs of the genusUca (Ocypodidae). In fiddler crabs, males have one claw which is greatly enlarged and which is used for communication, particularly for attracting a mate.Another conspicuous difference is the form of the pleon (abdomen); in most male crabs, this is narrow and triangular in form, while females have a broader, rounded abdomen. This is due to the fact that female crabs brood fertilised eggs on their pleopods.

Behaviour

Crabs typically walk sideways (a behaviour which gives us the word crabwise). This is because of the articulation of the legs which makes a sidelong gait more efficient. However, some crabs walk forwards or backwards, including raninids, Libinia emarginata and Mictyris platycheles.Some crabs, notably thePortunidae and Matutidae, are also capable of swimming.
Crabs are mostly active animals with complex behaviour patterns. They can communicate by drumming or waving their pincers. Crabs tend to be aggressive towards one another and males often fight to gain access to females.On rocky seashores, where nearly all caves and crevices are occupied, crabs may also fight over hiding holes.
Crabs are omnivores, feeding primarily on algae, and taking any other food, including molluscs, worms, othercrustaceans, fungi, bacteria and detritus, depending on their availability and the crab species. For many crabs, a mixed diet of plant and animal matter results in the fastest growth and greatest fitness.
Crabs are known to work together to provide food and protection for their family, and during mating season to find a comfortable spot for the female to release her eggs.

Characteristic Of Frog And Crab



What is frog?

Amphibians
Frogs are members of the zoological class called Amphibia.
Amphibians are cold-blooded (or poikilothermic) vertebrate animals. They differ from reptiles in that they lack scales and generally return to water to breed.
They are one of three types of Amphibians. Anura, also called Salientia, (frogs and toads), caudate (salamanders and newts) and caecilians (worm-like amphibians).


Herps and Herpetology
Amphibians together with reptiles make up a larger group called Herps. The study of reptiles and amphibians is called Herpetology. Herp comes from the Greek word herpeton, which basically means "creepy crawly things that move about on their bellies."
A herptile is an individual herp. A person who keeps and breeds herps is called a herpetoculturist and the hobby is called herpetoculture.

 Generally speaking, though, when we think of frogs, we generally picture what are called "True Frogs"....
members of the family Ranidae, containing more than 400 species. 
These frogs have the characteristics of:

  • two bulging eyes
  • strong, long, webbed hind feet that are adapted for leaping and swimming
  • smooth or slimy skin (generally, frogs tend to like moister environments)
  • Frogs tend to lay eggs in clusters.
Frogs from this family can be found on every continent except Antarctica. They are referred to as the "true frogs" because of their generalized body form and life history: the so-called generic frog. 
Members of this family include the bullfrog, common frog, green frog, leopard frog, marsh frog, pickerel frog, and wood frog.

Life Cycle of a Frog

True Love

When Frogs mate, the male frog tends to clasp the female underneath in an embrace called amplexus. He literally climbs on her back, reaches his arms around her "waist", either just in front of the hind legs, just behind the front legs, or even around the head. Amplexus can last several days! Usually, it occurs in the water, though some species, like the bufos on the right mate on land or even in trees!

While in some cases, complicated courting behavior occurs before mating, many species of frogs are known for attempting to mate with anything that moves which isn't small enough to eat!






While in the amplexus position, the male frog fertilizes the eggs as they get are laid. Frogs tend to lay eggs single eggs in masses, whereas toads usually lay eggs in long chains.
Some frogs leave after this point, but others stick around to watch over the little ones. Some have very unusual ways of caring for their young. You'll learn about some of those later in this tour!.

Egg
Frogs and Toads tend to lay many many eggs because there are many hazards between fertalization and full grown frogness! Those eggs that die tend to turn white or opaque. The lucky ones that actually manage to hatch still start out on a journey of many perils.
Life starts right as the central yolk splits in two. It then divides into four, then eight, etc.- until it looks a bit like a rasberry inside a jello cup. Soon, the embryo starts to look more and more like a tadpole, getting longer and moving about in it's egg.
Usually, about 6-21 days (average!) after being fertilized, the egg will hatch. Most eggs are found in calm or static waters, to prevent getting too rumbled about in infancy!
Some frogs, like the Coast foam-nest treefrog, actually mate in treebranches overlooking static bonds and streams. Their egg masses form large cocoon-like foamy masses. The foam sometimes cakes dry in the sun, protecting the inside moisture. When the rain comes along, after developement of 7 to 9 days, the foam drips down, dropping tiny tadpoles into the river or pond below.

Tadpole
[tadpole]


[tadpole]Shortly after hatching, the tadpole still feeds on the remaining yolk, which is actually in its gut! The tadpole at this point consists of poorly developed gills, a mouth, and a tail. It's really fragile at this point. They usually will stick themselves to floating weeds or grasses in the water using little sticky organs between its' mouth and belly area. Then, 7 to 10 days after the tadpole has hatched, it will begin to swim around and feed on algae.
After about 4 weeks, the gills start getting grown over by skin, until they eventually disappear. The tadpoles get teeny tiny teeth which help them grate food turning it into soupy oxygenated particles. They have long coiled guts that help them digest as much nutrients from their meadger diets as possible.
By the fourth week, tadpoles can actually be fairly social creatures. Some even interact and school like fish! 



Tadpole with legs
[tadpole]



[tadpole]After about 6 to 9 weeks, little tiny legs start to sprout. The head becomes more distinct and the body elongates. By now the diet may grow to include larger items like dead insects and even plants.
The arms will begin to bulge where they will eventually pop out, elbow first.
After about 9 weeks, the tadpole looks more like a teeny frog with a really long tail. It is now well on it's way to being almost fullgrown! 



Young Frog, or Froglet
[froglet]By 12 weeks, the tadpole has only a teeny tail stub and looks like a miniature version of the adult frog. Soon, it will leave the water, only to return again to laymore eggs and start the process all over again! 



 
Frog
By between 12 to 16 weeks, depending on water and food supply, the frog has completed the full growth cycle. Some frogs that live in higher altitudes or in colder places might take a whole winter to go through the tadpole stage...others may have unique development stages that vary from your "traditional" tadpole-in-the-water type life cycle: some of these are described later in this tour.
Now these frogs will start the whole process again...finding mates and creating new froggies.






Deforestation

 I was a rubber tree. I come from a forest with full of natural vegetation and unique. Around me are friends I like bananas, durian tree, apple trees and many other friends that  come from a variety of plants. Our life is always peace and harmony as well as animals and insects that often plays around me and make me their home.


Until one day, I listen to screaming for help from my friends, from a distance I saw my friends die cut by a group of people who fell trees without any compassion to us as the trees. One by one in front of my friends in the cut, until my turn I was cut .. Ouchh! the pain felt when the machine is in place cutters in my body, very bitter taste, I shout loudly but I am a rubber tree and no one heard my screams of pain. But the more I was sympathy to animal and insects that make me their home. They lost their homes, screaming for help and ran away, I saw a squirrel in front of me that crushed dead trees, baby birds who had waited for her mother to the feed has also died. People yet do this on our natural environment.


Once my body cut into several parts, I am gathered with friends I also have the cut. Although I have finished the cut, but the pain was still there, such as being cut down. While this pain I see around me, how sad it because I was once living is a dreary place, peaceful, beautiful while animals and insects. but everything was destroyed. Does the all human are cruel like this. I feel so sad, this might be the end of life my way.
After living in align me and the branches and trees burned, environmental changes have occurred, I can feel the temperature in the area was hot, there are also often occurrence of landslides and the landslide had closed the hole drains and ditches but when the rains often flooding, this is all happening because humanity that only catch up without thinking about the impact on the environment. Humans must be responsible! .. Here, I want to remind anyone involved in deforestation or pollution, stop doing cruelty to the environment, not only affects the natural ecosystem but also human!.

In conclusion, God created man at the inheritors of the earth, to preserve natural ecosystems so that all ecosystems on earth in a stable condition also caused people and the environment are interdependent. For those who are involved in deforestation stop before its too late is also wrong at the law.
