My favorite organism is amoeba. Amoebae (plural amoeba) are protozoans that belong to Amoebozoa kingdom. They consist of single celled organisms that have no definite shapes. These organisms are categorized as protist, a group of neither animals nor plant. Because Amoebae are mostly very tiny organism, microscope is needed to observe them while some are large enough to be observed with naked eyes. The most widely known Amoeba is probably Amoeba proteus. It sizes approximately around 0.028 inches (0.7mm) that is visible to naked eyes and the largest would be about 1mm. Amoebae can typically be found in fresh water like pounds, rivers, wet soil and around decaying vegetation. Some others exist in the human and the animal systems that include species that cause serious disease, for example, amoeba called the amoeba naegleria, as known as brain eating amoeba that live in warm water. They can infect you and slowly destroy your brain tissue and the result almost always will be the death, however, the majority of amoebae are harmless to humans. Interestingly, the name of Amoeba comes fro...
Cephalopods are known to be exceptionally intelligent by invertebrate standards and in some respects even rival “higher” vertebrates. These animals have many highly evolved sensory and processing organs that allow them to gain a greater understanding of their environment and their place within it. Due to their advanced structures, many of which are analogous to vertebrate structures, and abilities they have been widely studied. Their methods of learning have been of prime interest and many experiments have been conducted to determine the different ways in which octopuses can learn. From these experiments four main kinds of learning have been identified in octopuses: associative learning, special learning,
Jellyfish are a unique and interesting species. Even though jellyfish look complex they are simple. They have very little internal systems, such as respiratory, circulatory, excretory, and nervous systems. Even though they don’t have a nervous system they have the ability to sting and kill prey to survive. Chemicals can cause them to glow. They can move by expansions and contractions. They can reproduce both asexually and sexually. They are simple invertebrates but yet are still unique and interesting. Jellyfish are fascinating and more complex than they appear to be.
Crustaceans belong to the Arthropoda Phylum, which includes critters like ants, spiders, and centipedes. I know! Crazy to think that a delicious crab is in the same group as a spider! But they share similar characteristics. For starters, members of the Arthropoda Phylum do not have a backbone like you and me, so they are called __invertebrates__. And, as mentioned earlier, their skeleton is external, which is referred to as an __exoskeleton__.
Unique Fact: Humans cannot contract the amoeba from another person or by drinking contaminated water. The amoeba enters your body through your nose, by contaminated water and voyages to the brain through the nerves that transmit the sense of smell.
To understand the human gut health and aetiology, the first step is to understand the gastrointestinal (GI) microflora and its distribution through the digestive system [2]. The human GI tract is inhabited by trillions of microorganisms, which together is known as the microbiota [5]. These microorganisms come from both archeal and bacterial domains. Bacteria are the predominant kingdom of organisms and it is composed mainly by five bacterial phyla: Firmicutes, Bacteroidetes, Actinobacteria, Proteobacteria and Verrucomicrobia [3]. The great majority of mammalian gut microbiota belongs to the three phyla: the Gram-negative anaerobe Bacteroidetes, the Gram-positive Actinobacteria and Firmicutes [5].
Two unknown bacteria were provided that were labeled “12A” and “12B”. Both bacteria were then used individually following aseptic technique to create heat-fixed smears. Both bacteria were strategically placed on the slide in order to prevent cross contamination and inaccurate results. A total of three slides were made in order to ensure accuracy. The heat-fixed slides were then Gram stained using the procedure listed in the manual; followed by observation under a Leica Dm500 microscope. The slides were observed under 4X,10X,40X and oil immersion and both unknown reactions were double checked by Dr. McLaughlin.
Microbes are microscopic life forms, usually too small to be seen by the naked eye. Although many microbes are single-celled, there are also numerous multi-cellular organisms. The human body has 10-100 trillion microbes living on it, making it one giant super-organism. Since the first link between microbes and diseases was made, people have been advised to wash their hands. Scientists, however, have recently started to investigate more closely how the microbes that call the human body home affect our health. While some microbes cause disease, others are more beneficial, working with our bodies in many subtle ways.
Arthropods are animals belonging to the phylum Arthropoda, which is the largest of all phyla in the Animal Kingdom, with more than one million species, making them almost 80% of the whole kingdom. These include insects, arachnids, crustaceans and many more, most of which are quite small, the biggest being the Japanese Spider Crab with a leg span of 3.5 meters and the smallest being the microscopic Plankton.

Although prokaryotes may seem more primitive than eukaryotes, they are among the most successful species on our plant and comprise a very large percentage of the total mass of all living things on earth. Simple, small, and single-celled organisms can reproduce quickly and evolve quickly. Prokaryotes can generate millions of progeny in a short period of time.
As urbanization continues to expand amphibian population are on a global decline. In many rural areas, the only wetland available for aquatic reproduction is artificial ponds. While some species are able to persist in such an environment the majority of amphibians are negatively affected. The introduction of non-native species along with habitat degradation affects the successful reproduction of these native amphibians. Therefore, an understanding of the relationship between these species and their habitat is essential for conservation. This research sets out to determine conservation priorities for pond breeding amphibians in the hopes of preserving their existing populations.
Susan Lindee and Ricardo Santos’ goal was to understand the contexts of genesis and development of biological anthropology around the world from an international standpoint, focusing on engagement with living human populations. Their contributors, scholars in history of science, science studies, and anthropology, were guided by key questions about national histories, collections, and scientific field practice.
Their flesh gradually becomes clear and their white skeleton becomes visible. Moreover, their whole body would be covered by fuzzy microalgae.
