Vertebrates use their backbones to move in a variety of ways. Observes and comments on the movement of fish, moray eels, newts, salmon, cheetahs, dolphins, birds, and babies. Highlights the differences and similarities of their movement. Motorized models reveal precisely how some animals' backbones move.

Features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition, and this helps clarify pronunciation and provides opportunities to transfer words from working to long-term memory. Also concludes with a critical thinking question. For this particular clip, students will focus on vertebrate.
There are millions of different types of animals on Earth, ranging from simple animals, such as sponges and worms, to more complex animals. Students focus on complex animals, specifically the major vertebrate groups: fishes, amphibians, reptiles, birds, and mammals. Specific examples of vertebrates are shown to illustrate the different characteristics of complex animals. Important terminology includes: vertebrae, backbone, gills, ectoderm, fins, metamorphosis, eggs, scales, feathers, and endotherm.
The story of the egg spans millions of years from the first vertebrates that dared to venture onto land to today’s mammals. This episode takes an in-depth look at the biology and history of oviparous and viviparous animals. Part of the "Eons" series.
Paleontologists today look at more than just fossil evidence to learn about organisms that lived millions of years ago. In this episode, host Emily Graslie seeks to answer the question, "How did mammals develop their specialized movements?" Part of "The Brain Scoop" series.
Identifies physical characteristics, adaptations, and survival tactics of various kinds of reptiles. Segment 1, Snakes: Describes how snakes move, eat, and reproduce. Segment 2, Crocodilians: Compares and contrasts alligators and crocodiles. Segment 3, Lizards: Looks at some unique physical adaptations of various lizards, such as basilisk lizard, Komodo dragon, Gila monster, and chameleon. Includes suggested classroom activities after each segment.
In 1898, two African lions began attacking railway workers in Tsavo, Kenya. First reports estimated that 135 people fell victim to these "man-eaters," but further research published in 2009 lessened that number to 35 individuals. Over the years, different theories as to what motivated these attacks have varied, and recently host Emily Graslie got to talk with two experts who are working towards finding an answer. Part of "The Brain Scoop" series.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. The class transforms into lizards in an effort to save Liz, who the class thinks is in trouble after leaving school. They find him at the mysterious "Herp Haven." Will the class be able to save Liz, or is she even in any danger in the first place?
Part of the "Branches on the Tree of Life" series. The phylum Chordata includes tunicates, sea lancelets, hagfish, and all familiar vertebrate animals. Explores how these seemingly diverse animals evolved and how the group is unified by four characteristic structures: a hollow dorsal nerve chord, a supportive notochord, gill slits, and a post-anal tail. Key milestones in vertebrate evolution include improvements in swimming and feeding, the evolution of paired fins and a primitive lung, movement onto the land, and the emergence of the amniotic egg.
Part of the "Life in Aquatic Environments" series. Places many of the organisms into an ecological perspective of hydras, planarians, annelids, aquatic insects, rotifers, protists, and all other organisms that provide food for fish and other vertebrates. Observes adaptations for planktonic life in daphnia and other cladocerans, copepods, rotifers, and planktonic algae. Explores bacterial decomposition, recycling of materials, adaptations for bottom life, and ecological relationships in the bottom community. Takes an underwater look at the highly specialized organisms that live in rapids, under rock communities, and in slower waters. Investigates adaptations for life in temporary wetland environments.
The Mexican free-tailed bat is one of the most abundant mammals in North America. Outside of San Antonio, Texas there is a cave that is home to over 40 million of these bats. Roosting in large numbers in relatively few areas makes them especially vulnerable to human disturbance and habitat destruction. Documented declines at some roosts are cause for concern because there is a delicate balance in the ecosystem that depends on the bats. There is also cause for concern among other bat species that are falling victim to white nose syndrome, which is a condition named for a distinctive fungal growth around the muzzles and on the wings of affected animals.
Think of earthworms and a few things come to mind: they make great bait for fishing, they aerate the soil, and they’re an excellent addition to a compost pile. But, what a lot of people don’t know is many earthworms are actually invasive species. Earthworms may be small but when they take over a forest, the impact is dramatic. They cause the rapid incorporation of organic material into the soil, changing its structure, chemistry and nutrient dynamics. What's known as the duff layer is suddenly removed, and this duff, or decaying organic material on the forest floor, is habitat for several species of insects, spiders, small vertebrates, bacteria and fungi. It is also the primary rooting zone for most plants.
Tongue taste areas The tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication, and is used in the act of swallowing. It is of importance in the digestive system and is the primary organ of taste in the gustatory system. The tongue's upper surface (dorsum) is covered in taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva, and is richly supplied with nerves and blood vessels. The tongue also serves as a natural means of cleaning the teeth. A major function of the tongue is the enabling of speech in humans and vocalization in other animals. The human tongue is divided into two parts, an oral part at the front and a pharyngeal part at the back. The left and right sides are also separated along most of its length by a vertical section of fibrous tissue (the lingual septum) that results in a groove, the median sulcus on the tongue's surface. There are two groups of muscles of the tongue. The four intrinsic muscles alter the shape of the tongue and are not attached to bone. The four paired extrinsic muscles change the position of the tongue and are anchored to bone. Do you have good taste? In this video segment, Dr. Linda Bartoshuk explores the sense of taste in humans - why we have it, and what happens when we lose it. Learn why the sense of smell is also important to our experience of food. Footage from NOVA: "Mystery of the Senses: Taste".
