HOW TERMITES DIGEST WOOD First a video of a Western Termite [at about 10x magnification]. Then we cut to the Termite's gut and look inside - first at 200x magnification, then at 1000x magnification. What you see is not a nano-machine, it is a Protozoan symbiont that lives in the Termite's gut. It actually digests the wood the Termite eats. Then it excretes sugars and nutrients that the Termite can use. The details get a little more complicated, because the Protozoan has its own symbiont, a Spirochete bacterium. At this point you may want to GOOGLE the words "Hypermastigote", "Trichonympha", "Termite symbiont", and "Termite spirochete".

WWW.GOODNEWS.WS Rabbit goodnews.ws Rabbits are small mammals in the family Leporidae of the order Lagomorpha, found in several parts of the world. There are seven different genera in the family classified as rabbits, including the European rabbit (Oryctolagus cuniculus), Cottontail rabbit (genus Sylvilagus; 13 species), and the Amami rabbit (Pentalagus furnessi, endangered species on Amami Ōshima, Japan). There are many other species of rabbit, and these, along with pikas and hares, make up the order Lagomorpha. The rabbit lives in many areas around the world. Rabbits live in groups, and the best known species, the European rabbit lives in underground burrows, or rabbit holes. A group of burrows is called a warren. Meadows, woods, forests, thickets, and grasslands are areas in which rabbits live.They also inhabit deserts and wetlands. More than half the world's rabbit population resides in North America. They also live in Europe, India, Sumatra, Japan, and parts of Africa. The European rabbit has been introduced to many places around the world. The rabbit's long ears, which can be more than 10 cm (4 in) long, are probably an adaptation for detecting predators. They have large, powerful hind legs. Each foot has five toes, with one greatly reduced in size. They are digitigrade animals; they move around on the tips of their toes. Wild rabbits do not differ much in their body proportions or stance, with full, egg-shaped bodies. Their size can range anywhere from 20 cm (8 in) in length and 0.4 kg in ...
***roach dissection - Digestive system This video shows a ***roach's dissected digestive system. These are a ***roach's dissected mouthparts. Their mouth organs, the maxilla, mandibles, and labium, are used to taste food and handle food pieces. ***roaches use their mandibles, or jaws, to bite and chew their food. From the mouth organs, the food passes into the foregut, or esophagus. The foregut opens into a crop, where undigested food is temporarily stored. From the crop, the food enters the gizzard. The gizzard is a muscular stomach with sharp teeth-like structures that grinds the food into smaller pieces. The gastric sacks contain bacteria that the ***roach uses to digest its food. The Malpighian tubules are the main organs of the ***roach's excretory system. The Malpighian tubules remove wastes from the hemolymph, in the body cavity surrounding the ***roach's organs and tissues. These organs also regulate the balance of water and salts in the ***roach's body. The contents of the Malpighian tubules are emptied into the midgut, which is also called the ileum. Most of the absorption of the food's nutrients takes place in the midgut, or ileum. In the hindgut, or colon, water, salts, and nutrients are reabsorbed from the feces and urine. The remaining wastes leave the body through the rectum, which is also part of the excretory system.

***roach dissection - Respiratory system This video shows a ***roach's dissected respiratory organs. The respiratory system of insects is made up of many branching tubes. The tubes start at openings, called spiracles, found on the surface of the ***roach. Air enters the ***roach's body through the spiracles. The spiracles are found in each of the ***roach's segments. The larger tubes are called trachea. Trachea are found close to the ***roach's dorsal vessel , or heart. The trachea branch into smaller tubes, called tracheoles. [show with arrow] The tracheoles surround all of the insect's organs and tissues. They supply the hindgut, or colon, with air. Air passes into the trachea and moves on into the tracheoles and finally into the body tissues. The oxygen in the air diffuses, or spreads into, the cells that form the tissues. Carbon dioxide leaves the cells and moves back through the tracheal system consisting of the tracheoles and the trachea and leaves the insect's body through the spiracles. In comparison, in humans oxygen and carbon dioxide is carried from and to the lungs by the blood in the blood vessels of the circulatory system. Humans do not have a tracheal system. This video is one of 89 videos that are part of an interactive multimedia software for grades K-5 entitled Backyard Bugs.
bunnies, chicken and turtle Rabbits are hindgut digesters. This means that most of their digestion takes place in their large intestine and cecum. In rabbits, the cecum is about 10 times bigger than the stomach, and it, along with the large intestine, makes up roughly 40% of the rabbit's digestive tract. Cecotropes, sometimes called "night feces", come from the cecum and are high in minerals, vitamins and proteins that are necessary to the rabbit's health. Rabbits eat these to meet their nutritional requirements. This process allows rabbits to extract the necessary nutrients from their food. Chickens in nature may live for five to eleven years, depending on the breed. In commercial intensive farming, a meat chicken generally lives only six weeks before slaughter. A free range or organic meat chicken will usually be slaughtered at about 14 weeks. Hens of special laying breeds may produce as many as 300 eggs a year. After 12 months, the hen's egg-laying ability starts to decline, and commercial laying hens are then slaughtered and used in baby foods, pet foods, pies and other processed foods. The world's oldest chicken, according to the Guinness Book of World Records, died of heart failure when she was 16 years old. Turtles are broken down into two groups, according to how they evolved a solution to the problem of withdrawing their neck into their shell (something the ancestral Proganochelys could not do): the Cryptodira, which can draw their neck in while contracting it under their spine; and the ...

Let's Play Super Mario 64 Part 17 - ***IN THING SUCKS Rhinoceros (pronounced /raɪˈnɒsərəs/) -- Greek ῥῑνόκερως -- often colloquially abbreviated rhino, is a group of five extant species of odd-toed ungulates in the family rhinocerotidae. Two of these species are native to Africa and three to southern Asia. The rhinoceros family is characterized by its large size (one of the largest remaining megafauna), with all of the species able to reach one ton or more in weight; an herbivorous diet; and a thick protective skin, 1.5--5 cm thick, formed from layers of collagen positioned in a lattice structure; relatively small brains for mammals this size (400--600 g); and a large horn. They generally eat leafy material, although their ability to ferment food in their hindgut allows them to subsist on more fibrous plant matter, if necessary. Unlike other perissodactyls, the African species of rhinoceros lack teeth at the front of their mouths, relying instead on their powerful premolar and molar teeth to grind up plant food. Rhinoceros are killed by humans for their valuable horns, which are made of keratin, the same type of protein that makes up hair and fingernails. Both African species and the Sumatran Rhinoceros have two horns, while the Indian and Javan Rhinoceros have a single horn. Rhinoceros have acute hearing and sense of smell, but poor eyesight. Most live to be about 60 years old or more. The IUCN Red List identifies three of the species as "critically endangered".
Humans - Herbivore, Carnivore or Omnivore? Are humans Herbivore, Carnivore or Omnivores? Insulting comments are not allowed. _________________ Herbivore? Carnivore? Omnivore? 1. Omnivorism (humans) The key category in the discussion of human diet is omnivores, which are defined as generalized feeders, with neither carnivore nor herbivore specializations for acquiring or processing food, and who are capable of consuming and do consume both animal protein and vegetation. They are basically *opportunistic* feeders (survive by eating what is available) with more generalized anatomical and physiological traits, especially the dentition (teeth). All the available evidence indicates that the natural human diet is omnivorous and would include meat. We are not, however, required to consume animal protein. We have a choice. 2. Apes Our closest relatives among the apes are the chimpanzees (ie, anatomically, behaviorally, genetically, and evolutionarily), who frequently kill and eat other mammals (including other primates). Their diet is fruit, leafs, seeds, meat (like: birds, mammals, pigs, antelope, and their faverite food: termites). Conclusion: they are omnivores. 3. Evidence of humans as Omnivores. 3.1 Archeological Record As far back as it can be traced, clearly the archeological record indicates an omnivorous diet for humans that included meat. Our ancestry is among the hunter/gatherers from the beginning. Once domestication of food sources began, it included both animals and plants. 3.2 Cell Types Relative number and ...
The Horse's Hindgut and Common Digestive Problems The horse's hindgut is critical to digesting fiber in a process called hindgut fermentation. However, the hindgut's ability to function is compromised especially when too much starch reaches the large intestine undigested. This kills off the good organisms, and can lead to serious problems like ulcers and colic. Learn more about how the hindgut works and some of the common problems associated with it.

The attack of the Rhinoceros Rhinoceros, often colloquially abbreviated rhino, is a name used to group five extant species of odd-toed ungulates in the family Rhinocerotidae. Two of these species are native to Africa and three to southern Asia. Three of the five species—the Javan, Sumatran and Black Rhinoceros—are critically endangered. The Indian is endangered, with fewer than 2700 individuals remaining in the wild. The White is registered as Vulnerable, with over 9000 remaining in the wild. The white rhino is actually not white at all. The name comes from "wide" referring to the wide square mouth that allows the rhino to eat broads of grass. The rhinoceros family is characterized by its large size (one of the largest remaining megafauna alive today), with all of the species able to reach one ton or more in weight; herbivorous diet; and a thick protective skin, 1.55 cm thick, formed from layers of collagen positioned in a lattice structure; relatively small brains for mammals this size (400600g); and a large horn.

Zebra Zebra are in the genus Equus, and are related to both asses and horses. Equine are one-toed herbivores that arose in the early Pleistocene Epoch about 2 million years ago. All equids forage primarily on fibrous foods, such as grasses and sedges, as well as bark, leaves, buds, fruits, and roots. Equids employ a hindgut fermentation system, utilizing an enlarged appendix in which plant cell walls are only incompletely digested. By ingesting large quantities of food, they achieve extraction rates equal to those of ruminants. Zebras mostly inhabit the grasslands and savannahs of Africa. Like all equid, they are highly social mammals that exist in herds comprising of a senior stallion and his harem of mares. They usually only have one foal a year after undergoing a gestation period of 11.5 months (12.5 months in the Grevy's Zebra). There are a number of theories surrounding the advantage of zebras having a coat of black and white stripes. It is speculated that the stripes confuse predators, such as lions, making it more difficult for them to isolate and cull a single animal from the herd. A park ranger from Africa I know thinks that the stripes provide camouflage out on the hot savannah plains. He had noticed that the heat vapor rising from the ground could completely conceal an entire herd of zebra standing in front of him.

Nurmastini Sufina Bujang UF/IFAS/FLREC (Dr. Nan Yao Su's Group) Research Background Cellulose is the most abundant biopolymer and the ability of termites to digest cellulose as their food source is a characteristic shared by very few other organisms in the food chain. Lower termites digest cellulose using independent dual cellulose-digesting systems consisting of endogenous (termite-derived) and exogenous (protozoan-derived) factors. However, the system(s) within higher termites remains debatable because instead of protozoans, they harbor bacteria in their hindgut and these bacterias role in cellulolysis is still unclear. My current research interest is the phylogenetic diversity of cellulase genes in higher termites and to separate them into termite-derived or bacteria-derived genes. Ultimately, I am interested to compare these genes across nutritionally diverse (xylophagous, fungus-growing and humivorous) higher termites.
